Control Design recently took a look at the current state of remote I/O. Contributing Editor Hank Hogan suggests that remote I/O is becoming “smaller, faster, customizable and intelligent” thanks to innovations within the industry.

The article highlights several examples of companies who have saved money and increased the functionality of their processes by utilizing remote I/O. In one example, an electrical contractor uses automated PLC systems to control construction, excavation and mining machines. In many cases, the machines at the 

construction site were a large distance from the main processor – in some cases up to a mile away. This meant using expensive wiring to span the distance and sending a technician on-site if one of the cables failed.

Using remote I/O solves many of these problems. Two locations can be connected via a single twisted wire pair, Ethernet or fiber-optic communication link. Moore Industries offers a wide range of remote I/O solutions including the NCS NET Concentrator System®, which can be used to send just a few – or hundreds – of process signals between the field and a control system whether close by or remote. It’s ideal for creating new monitoring and control networks and also for leaving existing “legacy” sensors, analog instruments and valves in place while taking advantage of digital signal transmission capabilities.

The NCS has several features that make it ideal for plants and remote environments. It offers enhanced RF/EMI protection that eliminates ground loops and protects against the effects of electrical "noise" found in busy plants. It can also be installed in harsh environments with an operating range of -40°C to +85°C (-40°F to +185°F).

For more information about the use of the use of Distributed I/O in plant settings, please download our "Peer-to-Peer Distributed I/O Systems Solve Signal Interface Problems" white paper.

Another option available for connecting field instruments to control systems is to use wireless I/O. This method completely eliminates the need for wiring, makes it easy to expand a network and allows for the transmission of signals across large distances.

The WNM Wireless Network Module from Moore Industries can be used in conjunction with the NCS to communicate with just one – or multiple – WNM modules configured as Remote modules in a Point-to-Point system. In a Point-to-Multipoint architecture, modules can be configured as repeaters to relay signals when a direct line of sight does not exist between a Master and Remote modules, or to significantly extend the transmission distance allowable within a WNM network.

Q: We have been using Moore Industries DCA series switches for some time. Is there a like-for-like digital microprocessor-based replacement available?

A: The SPA2 series is a microprocessor-based design with all of the capabilities of nearly any permutation of the DCA. It does have a different form and fit, so we will need to know the complete model number of your DCA unit in order to recommend a SPA2 model.

The most common type of DCA mounts to a back panel with four screws, such as model DCA/4-20MA/DH1L1/117AC [UB]. We can provide the SPA2 with the same mounting bracket so that it fits the same footprint and hole pattern.

Having a WirelessHART gateway available provides end users with many potential uses. One of them is in moving discrete inputs via the WirelessHART gateway in a simple and affordable manner. This can be easily accomplished using the unique capabilities of Moore Industries’ TCM Temperature Concentrator System and the BULLET WirelessHART Adapter.

Using the BULLET, 16 inputs can be sent from the TCM via WirelessHART to the gateway. Essentially, what this is doing is converting the contact closures to binary 0s and 1s so they can be read by a HART, MODBUS RTU, MODBUS/TCP master or any host connected to the WirelessHART gateway. By using a parallel resistor and implementing some basic configuration, the TCM can sense a discrete contact input status and scale it as a binary 0 or 1 for the host system.

Here are the steps needed to accomplish this:

Inputs

For each discrete input, wire the discrete as though it is a 2-wire resistance input to each TCM channel. Install a nominal 1000Ω resistor in the same input terminals. When the discrete is closed the input will read ~0Ω; when the discrete is open the input will read ~1000Ω.

Configuration

Using the TCM PC Configuration Software, configure the input for 2-wire resistance. Leave the range of at the default setting of 4000Ω.

Scaling

Since discretes are reported as binary 0s and 1s, custom curves can be used for each discrete input to create either a 0 or a 1.
•0/Open Contact = ~1000Ω
•1/Closed Contact = ~0Ω

Once this is done, you can connect the TCM to your WirelessHART network using the BULLET or directly wire the TCM to your HART input card.

This input and configuration scheme is not unique to the TCM: you can measure discrete inputs with any of our modern temperature products with a digital output (such as the THZ³, TIM, TMZ, TPZ and TFZ). This creates a range of multi-channel and single-channel solutions for converting discrete inputs to HART, MODBUS, PROFIBUS PA and FOUNDATION Fieldbus protocols.

Q: I am monitoring up to 13600 Hz from a magnetic pickup on a gas turbine for speed indication and would like to use the FDY Frequency-to-DC Converter. Are either the PRG input or the 10-250V input handle this frequency?

A: Both input options can handle this frequency.

Normally the PRG input is correct for magnetic pickups. Some of them will put out a pulse voltage above the FDY's max of 30VAC, but it can be lowered by moving the pickup farther from the target. Use the FDY/10-250AC if you know for sure that the voltage pulse will be above the FDY/PRG’s upper limit. However, with this model, the pulse must be at least 10VAC.

Please note that the FDY  with the 10-250AC input is not available with I.S. approval.

Q: I have a question about the ECA-DIN Current and Voltage Alarm with the DH1L1 (Dual, High/Low, Failsafe) output option. The literature for the product says that "the failsafe relays are de-energized in an alarm condition or during power loss to the unit." Is this statement also true if there is a loss of input signal such as a broken wire?

A: The Failsafe setting means that the relay coils are de-energized in the alarm state. Naturally, if power is lost they will be de-energized. In case of loss of signal, the ECA will perceive the condition as a low signal and behave accordingly. That is, if you have a low alarm setting, the alarm will be activated. If you have a high alarm set, it will not be activated.
If you need more functionality such as being able to discern between a low signal and a lost signal, we recommend the SPA2. Unlike the ECA, it is a microprocessor-based design. This means that it can be configured for a variety of alarm and input signal conditions.

We know it is easier for many customers to communicate using MODBUS RTU protocol than HART protocol and that makes the HCS HART® Concentrator System a very popular tool.

We also know customers want more diagnostic information so they can access the health of their processes and instrumentation. HART Command 48 is what the industry and the HCS  uses to retrieve diagnostic information from the HART slave device, whether that is a transmitter or a valve positioner. The HCS will not implement Command 48 unless you turn on that feature by checking “Acquire Additional Status” on the HART tab of the configuration software.

Once enabled, if your HCS has firmware version 4 or earlier, the HCS retrieves Status bytes 0 through 5 and populates the diagnostic data into MODBUS registers. With 6 bytes by 8 bits each that is 48 pieces of information. Should you be using one of our newer HCS with firmware version 5 or higher, we pull 25 bytes or 200 bits of diagnostic data and allow it to be read by the MODBUS master.

Of course, the specific diagnostic information is under the control of the manufacturer of the transmitter or positioner, but the HCS makes it easily readable.

Are you or your customers taking advantage of this powerful tool?

The original goal when creating the WORM Flexible Temperature Sensor was to provide a sensor that could be cut in the field to accommodate various size wells and assemblies. Experience has proven this design helps with other obstacles in the field:

•Dirt, mineral deposits, corrosion scaling and other debris accumulates on the inside of the wells over time.

When you start with a 0.25” O.D. sensor and a 0.26” I.D. well, this added debris makes it very difficult to get sensors in and out of the wells. The WORM has an O.D. of 0.237”, which gives it an advantage to get past the debris to achieve an accurate reading.
•Horizontally-installed wells have a tendency to sag with time and temperature. This means removing and reinserting a rigid sensor can present challenges. The flexible design of the WORM makes installing replacement sensors easier.
•The solid sheath portion of the WORM is only about 1.5” long, which is much shorter than traditional solid sheath sensors. This gives the WORM advantages in applications where measurement speed is critical. The WORM is 30 percent faster than traditional solid sheath sensors, where the long solid sheath serves as a heat sink that sucks heat away from the hot tip of the sensor. The thermal differences have to stabilize before the tip of the long solid sheath can achieve an accurate process temperature reading. That same effect is eliminated in the WORM since the sheath is only 1.5” long and always at the tip of the well.
•With the smaller mass of the WORM sensor, you also gain more durability in high vibration applications versus standard sensors.
•Replacing an old, straight sensor is easy and fast with the WORM sensor. The WORM’s design allows the user to install and replace an older straight sensor by going through the enclosure. During installation, the WORM bends around and through the top or face of the enclosure. It slides through the enclosure’s entry port and snaps into place without removal of the enclosure, rigid conduit, connection head or any assembly components.

Q: We are looking to take an RTD or thermocouple signal input and output it to two 4-20mA outputs. We also could take the same temperature input and output the same signal twice. What are our options?

A: Using our HIM HART Interface Monitor along with a HART temperature transmitter such as the THZ3 is the most accurate solution. The HIM polls the THZ3 via HART and offers up to three separate and isolated analog outputs. Other options include::
A loop-powered TRY temperature transmitter and the ECT-DIN signal splitter. The splitter provides the loop power to the temperature transmitter and receives its signal. It then provides two isolated outputs. The ECT-DIN can be powered with 24DC, 117AC or 230AC.

Models:

•TRY/PRG/4-20MA/10-42DC [DIN]
•ECT/4-20MA/2X4-20MA/117AC/-TX [DIN]

A temperature transmitter such as the CPT and a signal isolator such as the ECT-DIN that are both line-powered. The output of the transmitter is to be connected in series to the input of the isolator and to one of your two loads. The output of the isolator goes to your other load.

Models:

•CPT/TPRG/0-20MA/117AC [DIN]
•ECT/4-20MA/4-20MA/117AC [DIN]

Want to see exactly how our SIL 3-capable STA Safety Trip Alarm serves as a logic solver that goes beyond what customers would expect from a standard alarm trip? A video available at our Interface Solution Video Library shows how the STA can initiate emergency shutdown procedures or alert personnel of unsafe process conditions.

The video is hosted by journalist and industry expert Peter Welander and features a demonstration of how the STA serves as a Single Loop Logic Solver in Safety Instrumented Systems (SIS). In the video, the STA monitors a “hot pot” filled with water. When the temperature goes above or below set points, dual alarm outputs on the STA signal a warning that an unsafe state has been reached. The video also shows how a third alarm monitors input or instrument faults such as a failed sensor or input signal.

The STA performs some of the same functions as expensive safety PLCs but is more affordable and easier to program. The process alarm trips and analog outputs are user configurable via front-panel push buttons. Configurations can be downloaded to multiple STA units with a free software utility program. It has been subjected to extensive testing by Exida and is fully compliant to IEC 61508. The STA is approved for single use in Safety Instrumented Systems (SIS) up to SIL 2 and in redundant architectures (1oo2, 2oo3, etc.) up to SIL 3.

The newly-released “Vetting Smart Instruments for the Nuclear Industry” white paper details how Moore Industries has designed and configured key products for nuclear safety-critical applications – particularly in the United Kingdom. Moore Industries’ early experience with the EMPHASIS assessment tool in the UK helped further refine the company’s approach to building products designed for functional safety and use in the global and UK nuclear industry.

Moore Industries worked with the Control and Instrumentation Nuclear Industries Forum (CINIF) in the UK on the conceptual development of the EMPHASIS assessment tool for smart instruments intended for use in nuclear safety-critical applications in the UK. Released in 2005, EMPHASIS provides a common framework for determining the suitability of devices in nuclear industries. Earlier designs for process control and safety systems used “good engineering practices and experience” as guidelines. As functional safety awareness grew and software-based products became more complex, standards such as IEC 61508 evolved to create more comprehensive guidelines for implementing safety.

Moore Industries’ compliance with IEC 61508 significantly contributes toward the EMPHASIS assessment for Production Excellence, one of two “legs” used to substantiate safety to the regulator. The second leg involves Independent Confidence Building Measures – measures and techniques such as Static Analysis or Statistical Testing on a product’s source code to prevent potential systemic failures and also taking into account the application demands of the device to be deployed.

Moore Industries has been assessed against and used the EMPHASIS tool to achieve approval for four smart instruments, with a fifth instrument currently in the approval process. The “Vetting Smart Instruments for the Nuclear Industry” white paper briefly outlines the steps that Moore Industries took to ensure that these products were designed following strict adherence to the IEC 61508 standard and how using the EMPHASIS process allowed the company to improve the design and configure new and existing products for safety in nuclear-related fields.

Controlling electricity costs is a major factor in the management of a manufacturing plant. It’s not uncommon for electrical utilities to charge a premium rate for power used during “peak” periods. If a manufacturing plant knows when these peak hours are, they can schedule major production for other time periods and save a significant amount of money.

Moore Industries helps manufacturing plants monitor peak demand with our PWT Watt Transducer. It can be used to help analyze power usage trends and find out when peak demands occur. Plants can shed non-vital loads during these times and reschedule the work for periods where power costs are lower.

Moore Industries-Belgium recently found success at the M+R 2015 show in Antwerp. The 37th edition of the show had a 12 percent increase in attendees from the previous show and Belgium Sales Manager René Michiels said that representatives from more than 50 companies came by the booth during the show and the leads are already starting to translate to orders.

The Moore Industries-Belgium team always goes out of their way to do big things to attract attention at shows and M+R 2015 was no different. This year they hired a magician to be at the booth and perform sleight-of-hand tricks using special Moore Industries playing cards highlighting our exida certified IEC 61508 Functional Safety instruments. People in the crowd were able to keep the cards after the trick was done. According to René, the illusionist was a big hit and helped to bring some excitement to our booth.

Q: I want to transmit temperature readings from 44 different four-wire RTDs over MODBUS using your TMZ PC-Programmable MODBUS Temperature and Signal Transmitter. Can I use the EMM Ethernet/MODBUS Interface Module of the NCS NET Concentrator System® to concentrate the outputs of the TMZ? I would like to have the EMM configured as a MODBUS RTU Master and the TMZs as MODBUS RTU Slaves and then output from the EMM as a MODBUS/TCP to my control system. Can this all be done?

A: Yes it can be. The EMM can be used as a MODBUS RTU Master and query multiple TMZ Modbus RTU Slaves.

If the RTDs are in clusters of four or more you can use an EMM with one or more TIM modules instead of four or more TMZs for a more economical solution. A separate stand-alone EMM MODBUS Master can still be used to poll EMM and TMZ MODBUS Slaves.

The RS485 port of the EMM is used for either MODBUS RTU Master or MODBUS RTU Slave functions. The Ethernet port is used for MODBUS/TCP (Slave only) communications.

The WORM Flexible Temperature Sensor truly is flexible in a number of ways. Not only does it bend to accommodate awkward mounting positions and locations but it also comes with a myriad of mounting options. The new RTI-4 datasheet highlights some of the most common applications for the WORM:

Standard WORM Sensor; Lead Length with Overall Jacket* and Cord Grip
Model Number Example: SEN / CL1.5 / D25 / S316 / -WSPT14 -LL120 –GRIP [SEN]
Uses: Surface measurements where lead wire protection is not needed. Non-abrasive environment.

*Jacket Material is Teflon or Braided Fiberglass.

Standard WORM Sensor; Lead Length with Overall Jacket and Spring and Cord Grip
Model Number Example: SEN / CL1.5 / D25 / S316 / -WSPT14 –LL120 –SPR24 –GRIP [SEN]
Uses: Anytime you want the compressed spring to keep the sensor in contact with the well or hot surface. When used with the WORM Nose the spring adds weight to keep the sensor in the Nose. Increased protection of the lead wire against abrasion.

Standard WORM Sensor; Lead Length with Overall Jacket and SS Braid and Cord Grip
Model Number Example: SEN / CL2 / D25 / S316 / -WSPT14 –SSB120 –BOOT –GRIP [SEN]
Uses: The SS Braid provides excellent abrasion protection while maintaining flexibility of the lead wire. The braid and wire can easily round bends and should be used any time you need to pull the lead wire in adverse conditions.

Standard WORM Sensor; Lead Length with Overall Jacket and Flex Armor and Cord Grip
Model Number Example: SEN / CL2 / D25 / S316 / -WSPT14 –FLEX84 –BOOT –GRIP –LL36 [SEN]
Uses: The Flex Armor provides mechanical protection for the lead wire. Used most often with surface mount fittings or when conduit or Panduit are not available for the lead wire. Protects against anything striking the lead wire.

Direct Immersion of WORM Sensor with Flex Armor Cable and Cord Grip
Model Number Example: SEN / WSPT14 / D25 / S316 / -CL2 –FLEX24 –SSF11 –BOOT –GRIP [SEN]
Uses: This compression fluid seal fitting allows you to set the depth of the sensor and then lock it in. The same Flex Armor as above is used to protect the wires.

ARC Advisory Group posted highlights of its recent ARC Industry Forum to their website. Several sessions focused on the “ongoing automation challenges facing end users across a variety of industrial sectors.” Many of the challenges faced by plant operators involved managing increasingly complex systems – especially when dealing with multiple generations of automation implemented in different stages of a plant’s expansion or refurbishing. 

The result is an increasingly varied number of automation technologies deployed in plant settings. While automation professionals recognize the value of automation processes, many people outside of an infrastructure’s automation community do not understand the value of automation or take it for granted. According to ARC Advisory Group, the automation community needs to understand how to communicate the benefits of automation to senior decision makers and other stakeholders.

Moore Industries’ products help companies solve challenges in integrating diverse automation solutions – including plant expansions where installing additional wiring is cost-prohibitive or not possible. A prime example is the NCS NET Concentrator System, which provides a real-time signal gateway between the field or factory floor and your control strategy and is the ideal solution when you need to network new and existing “legacy” process sensors, instruments and final control elements with computer-based monitoring and control systems.

Other Recent Industry News:

Automation World has a piece on the rise of the Field Device Tool (FDT) standard to help establish “a common communication method between field devices and control or monitoring systems that are used to configure, operate, maintain and diagnose intelligent field instrumentation in both factory and process automation applications.”  Moore Industries’ THZ³ and TDZ³ Dual Input Smart HART Temperature Transmitters are HART & DTM Programmable with user-oriented basic configuration for fast and accurate setup. They can be programmed or monitored with any FDT compliant host or program, such as PACTware, utilizing our DTM.

Control Engineering explored how using wireless transmitters to take measurements such as flow, pressure, temperature and level in hazardous areas can reduce the time, expense and difficulty associated with installing and maintaining traditional two-wire or fieldbus transmitters.

Moore Industries has released a new video showing how PACTware has been integrated into the range of monitoring and configuration options available with the new THZ³ and TDZ³ Dual Input Smart HART Temperature Transmitters. In the video below, Moore Industries’ Customer Service Director Bob Croughwell walks viewers through the steps needed to setup and monitor transmitters with PACTware

The THZ³ and TDZ³ transmitters are DTM and HART programmable with user-oriented basic configuration for fast and accurate setup. Users can program or monitor the transmitters with any FDT compliant host or program – such as PACTware  – using the THZ³ and TDZ³ DTM. PACTware is gaining acceptance with customers worldwide who want a consistent and universal way to program, monitor and diagnose field devices.

Q: Do you have or do you know of a product that will filter out AC noise on an unshielded pair of wires carrying a 4-20mA signal over a distance of approximately 400 feet?

Top of Form

A: Any of our isolators have a common mode rejection AC filtering capability and can be used for this kind of application. 

One popular and versatile option for this is our ECT line. You can see it for yourself by checking out the datasheet, which contains all three types (input loop powered, output loop powered, and line powered.)

As record droughts continue across the western United States, having a viable and efficient solution for treating water supplies and wastewater created by industrial applications is essential. Effective treatments can save large amounts of water while problems in water and wastewater treatment can lead to increased costs, reduced water treatment, and even hazardous conditions.

Moore Industries has helped many different organizations improve their methods of treating water and wastewater. Whether the water is meant to be potable for public consumption or is being treated for reuse in other industrial applications, our products make operations more efficient and give site administrations more control over the process.

One example is the Onondaga County Water Authority (OCWA) in Central New York, which supplies water from Otisco Lake and Lake Ontario to more than 345,000 retail and wholesale customers. An upgrade allowed operators to upgrade the control room from manual analog control to a fully automated SCADA system utilizing Ethernet and MODBUS network communications.

At the heart of the system was NCS NET Concentrator System^®, a solution that employed isolated I/O modules to eliminate signal loop interference on the Ethernet control network. This stopped ground loops and signal aberrations at any location from affecting other measurements in the facility. In addition, the use of a field concentrator makes it easy to connect both existing and new process control signals and sensors to the control strategy. Such an approach expands control schemes by concentrating I/O remotely and significantly reduces wiring costs.

You can read about this in the “Distributed I/O and Remote I/O Solution Improves Performance and Reliability of Water Treatment Plant” white paper available at our website. You can also read the 555 Controller datasheet, which discusses how this product is specifically designed to assist in controlling the amount of chlorine in water and wastewater.

Q: Could you let me know the specific instances where the Fault Alarm trips on the STA Safety Trip Alarm are used?

A: The Fault Alarm (Alarm #3) is permanently set as a latching fault alarm that will trip if internally diagnosed faults or external faults – such as the loss of sensor or a “bad quality input” – occur. This alarm will trip without affecting the other relays being used to monitor the process. It can be used to warn of a failure without tripping more critical process alarms or shutting down the process.

More information can be found on Page 58 of the STA/TPRG Installation Manual.

Moore Industries’ reps are always hard at work helping customers. Here’s a look at some recent examples of how our reps were able to use Moore Industries’ products to solve their customers’ real-world problems: 

- A customer in Salt Lake City, Utah was in the process of expanding their refinery. As part of the expansion, they needed two cabinets with up to 12 DIN transmitters in each and the transmitters needed to be Intrinsically-Safe (I.S.). In addition, there was a larger pending job for 166 field-mount transmitters with displays. 

Regional Sales Manager Charlie Fetty worked with salesmen Carl Wilmarth and Scott Anderson at LaTech Equipment to come up with a solution: using a single transmitter for all their needs. The TDZ2 Smart HART Temperature Transmitters with DIN clips were used instead of traditional DIN-mount transmitters. This gave the customer his I.S. certification and the added benefit of the display. For the field-mount application, the TDZ2 was simply supplied with the BH housing. The result was a sale of almost $85,000.

- DanCo Systems has sold more than 100 microNCS MODBUS RTU Master and Distributed I/O Systems to a small oil production company near St. Louis. The oil company uses the microNCS as a data collection device for oil tank levels, flows and pressures. They communicate via wireless radios to a central operations building miles away from the field. DanCo builds remote boxes that go onto the well pads using the microNCS, radios and other conditioning instruments.

The giant tanks at Cushing, Okla. – the largest crude oil hub in North America – were only at 25 percent capacity just seven months ago. But Bloomberg Business reports that the same tanks are now nearing record levels, having gone from 18 million barrels in late July to 51 million barrels.

The primary reasons? Oil production has continued at high rates because oil trading companies are stashing crude oil while prices are low. Crude oil is trading at around $50 a barrel after being as high as $100 a barrel last summer. Traders are stockpiling in an attempt to sell their reserves once prices climb from their current levels. However, several factors indicate that prices may not rise soon and in fact could fall even further.

This is not just a financial concern for oil trading companies – it’s also a potential safety risk. Incidents such as the Buncefield fire in 2005 have shown that overfilled oil tanks can have devastating consequences. The current unprecedented levels of tank storage in North America means that the safety measures instituted after Buncefield are being tested more rigorously than ever before.

If tank overfill is a concern for your business, you need to read the “Logic Solver for Tank Overfill Protection” white paper from Moore Industries. It shows some of the logic solver possibilities available to a designer of a Safety Instrumented System (SIS) tank overfill protection system. This includes using a single loop logic solver such as the STA Safety Trip Alarm rather than a safety PLC. This is a simpler and more cost-effective approach that is sufficient in many instances. The “Logic Solver for Tank Overfill Protection” white paper discusses specific benefits of a single loop logic solver. It also provides a general step-by-step procedure to define and evaluate an SIS.

Moore Industries’ SSX and SST Safety Isolators and Splitters have achieved Factory Mutual (cFMus) approval as a Non-Incendive apparatus. This allows the products to be used in Class I, Division 2, Groups A, B, C and D Hazardous “Classified” Areas in both the United States and Canada. The SSX and SST are part of the Moore Industries FS FUNCTIONAL SAFETY SERIES and provide reliable isolation and signal conversion in potentially hazardous environments.

The two-wire (loop powered) SSX and four-wire (line/mains powered) SST have been certified by exida for single use in Safety Instrumented Systems up to SIL 2. With the new cFMus certification, the SSX and SST can now be used in both General (safe) and Hazardous Locations. This means that the SSX and SST can be used in process areas and industries where potentially explosive gases and vapors may be present including:

• Oil and natural gas refineries
• Offshore oil and gas rigs
• Chemical, petrochemical and pharmaceutical plants

The SSX and SST are ideal products for use in settings where safety is critical. They protect safety systems by isolating an SIS from basic process control or monitoring systems so that disconnections or other failures don’t impact the safety system. They also have 1500Vrms of isolating capability to protect safety I/O cards and systems from surges, spikes and transients in the field. Standard 20V/m RFI and EMI protection stops the harmful effects caused by radio frequencies and electromagnetic interference.

A plant upgraded to new Smart HART^® field transmitters but was still using their original field-mounted isolators. This meant that engineers in the control room were unable to access the HART transmitters – mitigating the benefits of performing the upgrade.

Moore Industries solved this problem with an installation of SSX HART Isolators. They offer full isolation and seamless HART communication capabilities with field transmitters including:

• Unlike traditional isolators, the SSX allows the HART signal to "pass" through so that critical HART diagnostic data can be read from the control room.
• HART PV data and status information is available at any termination point on both sides of the isolator..
• Calibration, field configuration or interrogation of the HART field transmitter can be accomplished from the host control system or asset manager..

The two-wire (loop powered) SSX and four-wire (line/mains powered) SST are part of the FS Functional Safety Series from Moore Industries and are exida-approved for use in an SIS up to SIL 3 in monitor mode, where only the input circuit is part of the safety function. For single use mode, the SSX and SST are approved for use in an SIS up to SIL 2.

One of the advantages of the WORM Flexible Temperature Sensors is that they can be mounted in so many different ways.
This is especially true if you need a skin (surface) temperature measurement. Moore Industries offers a variety of ways that you can clamp, bolt, weld or magnetically affix a WORM anywhere that a skin temperature measurement is needed.

Now you can access one datasheet to help you unlock all of the different skin temperature measurement options available with the WORM. The new RTI-4 datasheet has all of the information you need to make the right choice for your application. Items covered in the datasheet include:

• Multiple Mounting Options: As previously covered in the blog, the RTI-4 datasheet includes information on mounting options such as PAD Mounting, Exposed Air Thermowells and Protection Tubes, BAYONET Pipe Mounts, Remote-Mounted Sensors with Terminal Blocks and PIPE and TANK Mounts
• The WORM Nose: Ordering a lengthy assembly to measure temperatures – such as at the bottom of a tank – means expensive shipping costs. This can be avoided by using the WORM Nose option, which secures the sensor snugly at the bottom of an assembly that can be created on-site
• Flex Armor Cable: Adding a Flex Armor cable cover and fittings allow the WORM to easily fit into a standard threaded thermowell, increasing the flexibility and protection of the product.

The RTI-4 datasheet also has extensive ordering information to help you select the right WORM sensor along with a mounting option.

Moore Industries’ operations are dedicated to providing customers with solutions to their process control problems. This often means getting products to the field quickly. Here’s a quick look at the important role our Finished Goods Inventory (FGI) plays in the process:

Oil Surplus Puts Squeeze on Tank Levels

BloombergBusiness reports that falling prices combined with steady production means that crude oil storage capacity is beginning to become squeezed across North America. Prices for crude oil have fallen from $100/barrel to $50/barrel in recent months and trading companies are buying large quantities and storing it with the hope of selling it at a later time after prices rise.

The problem is that domestic oil production has not slowed down despite the low crude oil prices, putting a strain on storage capabilities. BloombergBusiness says that storage tanks in the Midwest are at about 70 percent of capacity while tanks in the East Coast are around 85 percent full. This means that tanks could quickly reach the edge of their capacity or that crude oil could also be stored in lines as well as tanks.

This pressure on crude oil storage could potentially create dangerous tank overfill situations. In these instances, companies need to have effective Functional Safety measures in place in order to prevent potentially catastrophic accidents. You can read more about how a single-loop logic solver such as our STA Safety Trip Alarm can provide protection by downloading our Logic Solver for Tank Overfill Protection white paper.

Other recent industry-related news:

• AutomationWorldExecutive Editor Aaron Hand wrote about the advantages of integrating control and safety functions. The article quotes ARC Advisory Group as pointing out advantages of integrated control and safety including “lower engineering and lifecycle costs, lower training and maintenance expenses, easier time synchronization and improved asset and event management.” However, challenges created by an integrated control and safety approach include “increased risk of common cause failures, the need for careful design to make sure that a BPCS failure does not affect the SIS and greater management challenges.”
• Control Engineering presented highlights from a recent ISA panel on the benefits of High-Performance HMI (HP-HMI). Panelists agreed that an effective HMI makes operators more aware of the situation at the plant or control location and better equipped to make important decisions.
• CONTROL ran a beginner’s guide to differential pressure level transmitters. The article showed how these transmitters work and why they are so important in eliminating overflow issues caused by high levels or pump damage caused by low levels.

The IPX2 Current-to-Pressure (I/P) Transmitter is approved to work with either instrument air or natural gas as a supply medium. When an I/P transmitter is installed on a natural gas line and used for the supply medium, liquid slugs can often enter the supply line and the transmitter itself. Depending on the size and duration of the slug, the I/P transmitter’s electronics may need to be removed for cleaning and draining or completely replaced.  The IPX2 Current-to-Pressure (I/P) Transmitter is approved to work with either instrument air or natural gas as a supply medium.

Depending on the size and duration of the slug, the I/P transmitter’s electronics may need to be removed for cleaning and draining or completely replaced.  

A new video produced by Moore Industries shows how the IPX2reduces production interruptions caused by liquid slugs. Available for viewing at the Interface Solution Video Library, the video shows how a field engineer or technician can quickly remove or replace the electronics module in the IPX2 with some simple tools. Within a few minutes, an electronics module can be removed for maintenance or replaced entirely by a new unit.
The video features Moore Industries engineer Rolando Toledo leading a step-by-step walkthrough of how to remove the electronics module of the IPX2 using a 3mm Allen wrench and a small Phillips head screwdriver. Rolando presents easy-to-follow steps for safely removing the electronics module without damaging any elements.

Along with showing how to remove the electronics module, the video also shows how the IPX2 minimizes the risks of debris entering the unit. It has been designed to be clog-resistant, with a large orifice and an easily replaceable internal filter that protects against clogging caused by debris.

Performing maintenance, repairs and upgrades at modern power plants is often challenging. Many power plants are built on instrumentation from companies that no longer exist or that use technology that has become outdated. Updating plants with new technology that can improve performance and reliability can be challenging and cost-prohibitive.

Moore Industries has a full range of instrumentation that can help power plants manage their transition to modern technology. One product detailed in our Automation and Instrument Solutions for Power Plant Applications line card is the NCS NET Concentrator System^®.

The NCS reduces wiring costs at older power plants by concentrating analog and discrete signals in peer-to-host and peer-to-peer architectures. The NCS can be used to send just a few, or hundreds, of process signals between the field and your control system, making it an ideal solution for creating new monitoring and control networks or for when you want to leave existing “legacy” sensors, analog instruments and valves in place, yet still take advantage of digital signal transmission.

Along with consolidating wiring, the NCS can help with several issues specific to power plants:

• Continuously monitor boiler tube temperatures for efficiency and provide alarms to warn of trouble in the event of overheating.
• Accurately monitor burner tip temperatures with industry-standard S-, R- and K-type thermocouples.
• Keep track of remote cooling pump temperatures even in high or low ambient conditions of -40°C to +85°C (-40°F to +185°F).
• Track oil tank levels in tank farms in oil-fired power plants.
• Monitor pH and conductivity to reduce tube oxidation and calcium deposits that strain flow and cause overheating.

The oil and natural gas industries rely on Moore Industries to provide them with solutions to a wide range of problems. From warning of potential safety threats over great distances to using natural gas as a pneumatic supply for current-to-pressure (I/P) transmitters at a remote site, our products allow engineers to design oil and natural gas systems that are more affordable, efficient and safer.

Want an example? New regulations forced multinational oil and gas company ENI to develop a communications link between the Devil’s Tower oil platform in the Gulf of Mexico and a drill ship more than 100km away to initiate an emergency shutdown in case of a serious event such as a “dropped object” impacting a submerged pipeline. At the same time, ENI needed a system that would not lead to false shutdowns that can cost $100,000 a day in lost production.

To meet its communications challenges, ENI developed a system across its Ethernet network using the NCS NET Concentrator System^® mounted on DIN rails. Using an Ethernet Interface Module in the control rooms of the oil platform and drillships, the drillship operator can use a push button switch to sound a klaxon horn at the oil platform control room to alert them of a potential threat. In addition, if communications are lost between the drillship and the platform and human operators are not available to respond, a shutdown procedure is automatically triggered.

You can read more about ENI’s installation of the NCS by downloading this white paper. 

Another example of how many companies are using Moore Industries’ applications can be seen in the video below. It shows how our HCS HART^® Concentrator System saves money and time by consolidating wiring and reducing power consumption at remote natural gas and oil production sites.

These are just a few of the many examples of Moore Industries’ products that are capable of solving problems specific to the oil and natural gas industries. For a more in-depth look at the full breadth of our solutions, make sure to check out our Oil and Natural Gas Well Head Line Card.

The WORM Flexible Temperature Sensor solves many installation problems associated with rigid temperature sensors. The WORM is simple to install and can be trimmed to fit into almost any application. It also can bend to accommodate awkward mounting positions and locations and it is completely embedded in the thermowell to ensure no outside influences affect the temperature measurements. 

Multiple mounting possibilities are available which also help to make it easier to install the WORM in almost any application where a skin (surface) temperature measurement is required. The new RTI-4 datasheet highlights some of the mounting options that can help to solve real-world installation problems:

PAD Mounting

The PAD completely surrounds the WORM, shielding it from external interference and providing maximum heat transfer to the sensor. This can be done through welding or bolting a PAD (-PAD option), attaching a Clamp PAD (-CLAMP) or affixing it via a magnetic pad (-MPAD).Exposed Air Thermowells and Protection Tubes

Both Exposed Air Thermowells (-EXP) and Protection Tubes (-PTB) are equipped with ½-inch NPT connections for mounting to a transmitter, field-mount enclosure or pipe. The -EXP is ideal for measuring both indoor and outdoor ambient temperatures. The perforated tube allows the sensor to have access to the open air while reducing the unwanted measurement fluctuations caused by air circulation. The -PTB is a sealed tube with a thinner wall for penetration in low-impact processes with low velocities or low pressure when you want faster responses than a thermowell can deliver.

BAYONET Pipe Mounts

The BAYONET (-BAY) option is a clamp-on pipe band mount designed to accommodate heavily insulated applications. The sensor extension allows for installation where the insulation is up to two inches thick.

Remote-Mounted Sensor with Terminal Block

Use a Remote-Mounted Sensor with Terminal Block (-RM) to remove the display from your process. The -RM comes with two housings: a transmitter in the specified connection head and a terminal block enclosed in an additional connection head with your selected sensor and fittings attached. With the -RM you can position your sensor in the heart of your process while keeping your transmitter in an easily accessible area.

PIPE and TANK Mounts

When you need to clamp a sensor to a pipe, you can use the PIPE (-PIPE) mount. Or you can order a TANK (-TANK) mount to weld the WORM into place, securing the spring-loaded sensor tip directly against the surface on which the temperature measurement is needed. With both mounts, the spring-loaded sensor is completely encased and features a flat tip, creating the best environment for maximum heat transfer to the probe.

Senior Applications Engineer J. R. Madden has extensive experience with all things relating to temperature. In this recurring feature, he'll address common customer issues and Moore Industries' solutions.

Q: Do I need to order anything differently if I’m measuring cryogenic temperatures?

A: When measuring temperatures below -10°F, readings are more stable and accurate when a wire-wound RTD element is used. Typical thin-film RTD elements do not perform well at these extreme temperatures.

Q: What about measuring temperatures above 850°F with an RTD? Should I specify a thin-film or wire-wound RTD element?

A: When using RTDs to measure temperatures above 850°F, we recommend using a wire-wound RTD element that is specially built to handle these high temperatures. Many thin-film RTD elements will experience high failure rates at these temperatures.  

If you require an RTD sensor for these temperature extremes, order a wire-wound (-WW option) element to ensure the best sensor performance and longevity.

Moore Industries is now a member of PACTware, a consortium dedicated to developing and maintaining manufacturer and Fieldbus-independent software for operating field instruments.

The company has integrated PACTware into the range of monitoring and configuration options available with the new THZ³ and TDZ³ Dual Input Smart HART Temperature Transmitters.

The THZ³ and TDZ³ transmitters are both HART and DTM (Device Type Manager) programmable. They can be easily programmed and interrogated from anywhere at any time on a 4-20mA loop. This can be done with a standard HART handheld communicator, a HART-compatible host or with any FDT (Field Device Tool)-compliant host or program such as PACTware utilizing Moore Industries’ DTM.

The PACTware software can be downloaded directly from Moore Industries website Download Center - Software and can be used with any manufacturer’s DTM. This utility provides comprehensively advanced programming capability for thorough transmitter configuration.

 The THZ³ and TDZ³ are the first Moore Industries products to use an FDT-complaint host with a DTM, which lays the foundation for utilizing PACTware with all future smart transmitters. Using an FDT host such as PACTware with a DTM is quickly becoming a worldwide standard as customers search for a universal method of programming, monitoring and diagnosing their field instruments. FDT/DTM technologies eliminate problems caused by vendors having different software programming packages or programming for multiple protocols (such as HART, FOUNDATION Fieldbus, and PROFIBUS PA).

The THZ³ and TDZ³ Dual Input Smart HART^® temperature transmitters are full of new features that provide more reliability and a higher degree of measurement accuracy. If you are looking at new temperature transmitters or are thinking about upgrading from your existing temperature transmitters, they are an ideal solution.

Want to know why you should consider the THZ³/TDZ³ temperature transmitters? We’ve come up with a “six-pack” of reasons:

1. Backup and Fail-Over Protection

The dual sensor inputs of the THZ³ and TDZ³ provide backup and fail-over protection. One sensor can be set as a backup for the other in case of a sensor failure. The transmitter automatically switches to the backup sensor so that the customer never loses their critical measurement. You can even use two different sensor types such as an RTD as the primary sensor and a thermocouple as the secondary sensor.

2. Average and Differential Measurement

Average the readings from two sensors, such as in a tank where stratification is a concern. Differential measurement allows you to monitor a temperature differential across a heat exchanger, for example, or for BTU calculations.

3. High-Select and Low-Select

You can use two sensors and select with the higher or lower of the two as a basis for control in processes that cannot tolerate running hot or cold. High-Select and Low-Select enables you to reduce the chances of an over-temperature or under-temperature condition occurring.

4. Device Intelligence

With the Device Intelligence feature set, you have a wide array of options for smarter control and monitoring including:

• Sensor drift and corrosion detection checks and alerts users when the sensor is drifting out of a preset range or when the resistance due to corrosion exceeds set parameters.
• Smart range alarms with four HART alarms – set to any input or calculated input –detect when the variable is within or outside of user preset limits.
• A High Availability option that enables the selection of how the AO behaves when there is an input failure or out-of-range value detected by the transmitter. This prevents nuisance alarms on startups or batch process shutdowns.
• Input simulation capability allows manual input of a direct or calculated value. This essentially simulates a real input, allowing users to test the AO or any HART diagnostic and range alarms.

5. Configuration Using PACTware and DTMs or using the HART DD

The THZ³ and TDZ³ transmitters are DTM and HART programmable with user-oriented basic configuration for the fast and accurate set. You can program or monitor the transmitters with any FDT compliant host or program – such as PACTware (available on our website along with a tutorial video) – using the THZ³/TDZ³ DTM. The FDT/DTM standard is widely used by customers worldwide who want a consistent and universal way to program, monitor and diagnose field devices.

Using the FDT/DTM gives you access to a range of setup and diagnostic features including:

• Programmable span, zero and input type values.
• Adjustable sensor trims offsets to compensate for measurement errors caused when a sensor is not performing to its rated curve specifications.
• Setting a damping time between 0-60 seconds to eliminate imprecise readings caused by noise and other insignificant process fluctuations.
• Viewing of real-time process values.

6. Trimming and Programming Custom Curves

The THZ³ and TDZ³ go beyond other sensor’s trimming capabilities by allowing trimming with two data points within the selected zero and span measurement range. This advantage allows a complete process range to be monitored while placing measurement emphasis on a specific segment of the range most critical to the process.

Beyond trimming, you can create up to four custom curves and apply them to any available device variables in the THZ³/TDZ³. You can program several properties for each curve including the number of active points in the custom curve, units of the inbound data to be processed by the curve (X values) and units of the outbound data that is the result of processing by the curve (Y values).

These are just some of the best new features in the THZ³/TDZ³.

Q: I am installing 24 SPA RTD transducers (Model: SPA/RTD/2PRG/U/-AO [DIN]) and I have a question about how the 4-20mA is powered. They are currently wired as loop-powered and I would like to confirm that this model supports loop-powered field devices.

A: The SPA/TPRG/2PRG/U/-AO [DIN] supports both source and sink mode on its current analog output. The default setting for the AO (analog output) is 4-20mA with the loop voltage sourced from the SPA. Please see Figure 4 in the SPA installation manual for changing the AO (analog output) to Current Source/Sink or a Voltage output.

Q: I need to order an FDY transmitter for monitoring up to 13600 Hz from a magnetic pickup on a gas turbine for speed indication. Do you recommend the PRG or 10-250V input option?

A: Either model is compatible with the frequency you mentioned. The PRG input is normally correct for magnetic pickups. Some will put out a pulse voltage above 30Vac (the maximum for the PRG input), but this can be lowered by moving the pickup farther from the target. Use the 10-250AC input if you are certain that the voltage pulse will be above the PRG’s upper limit. But with this model, the pulse must be at least 10Vac.

Please note that the 10-250Vac input is not available with I.S. approvals.

Model Examples:

FDY/PRG/4-20MA/12-42DC [HP]
FDY/10-250AC/4-20MA/12-42DC [HP]

“A Practical Guide to Temperature Measurement Accuracy,” the latest webinar from Moore Industries, was held on February 5.

Hosted by National Sales Manager Gary Prentice, the webinar focused on tips for getting the most accurate temperature readings possible. Selecting the right sensors, transmitters and 4-wire RTDs not only improves accuracy but also reduces drift, which means less frequent calibrations or verifications and a decrease in operating expenses. Gary also discussed eliminating errors caused by lead wires, environmental influences, and measurement errors. As usual, Gary did a great job taking complex topics and making them easy for everyone to understand. 

If you were not able to attend the webinar or would like to forward the webinar to a colleague or friend, we’ve made it available online.

Moore Industries has published a new white paper on an application using the WORM Flexible Temperature Sensors to measure the temperature of molasses during the production of beet sugar. Using the WORM as a replacement for standard thermowells allow site engineers to get more accurate temperature readings and maximize the amount of sugar recovered from the molasses.

American Crystal Sugar Company struggled with getting accurate temperature readings of molasses created during the process of extracting beet sugar. The molasses ran about 1 1/2-inches thick at the bottom of a pipe. Using a standard straight thermowell and a solid sheathed RTD sensor meant that the thermowell and sensor were only partially submerged. This led to inaccurate temperature measurements.

This was fixed by creating a custom thermowell with from 3/8-in. stainless steel tubing with a gentle bend at the end. A WORM RTD sensor was inserted into the end of the tubing. This allowed the tip of the sensor to be angled so that it was fully submerged in the molasses. The result is that site operators are able to get highly accurate temperature readings, which allows them to adjust their processes to extract more sugar from the molasses.

The Moore Industries Model 555 Controller handles the most sophisticated and demanding chlorination and dechlorination applications including complicated compound loop control. However, compound control is not needed in many instances. In numerous plants, chlorination and dechlorination control can be effectively accomplished using much simpler flow proportioned chemical feed control.

When running flow proportioned control, manually tweaking the chemical feed pump is accomplished by changing the Dose Setting. The Model 555 implements flow pace control and provides manual control of Dose.

Reasons to Use the 555 Controller:

• The 555 can be mounted in the control room and provide manual Dose Control without requiring travel to the pump house.
• If you are now implementing Dose Control by manually adjusting the pump stroke, you can give up that practice. Set the stroke long to improve control and better eliminate air entrainment and use the Model 555 Controller to adjust chemical feed through the pump’s speed control.
• Are you moving to peristaltic pumps for broader chemical feed rangeability, for reduced maintenance or to eliminate off gas binding? Peristaltic pumps don’t give you convenient Dose Control but the Model 555 will.
• The 555 does the trick if you are already using peristaltic pumps and need to manually adjust Dose to compensate for decreased flow from normal tubing wear.

How the 555 Controller Works:

• The flow signal from the plant transmitter is wired into the controller and the controller is configured for the Flow Pace Mode.
• When configured for Flow Pace Control, the 555 Controller’s Output = Flow x Dose
• We recognize that operators do not (or should not) deal with the chlorination controllers regularly. The 555 Controller’s functionality is limited to make user interface as simple as possible and to limit the possibility of adjustment errors. The only active keys are the Display Button and the Up/Down Arrows while all other keys are “locked out”. 
• When the display shows the Dose Setting, the Up/Down arrows will change the Dose multiplier. This then changes the controller output and chemical feed rate.

Moore Industries introduces the new universal SLD PC-Programmable Functional Safety Loop Display. The SLD features a large integral display that shows real-time process status in mA, percent, or any designated 5-character Engineering units (EGU). As part of Moore Industries’ FS Functional Safety Series products, the SLD is certified by exida as a SIL3 capable, non-interfering device for use in a safety loop.

The SPA2IS end-users love this feature. Watch this tutorial to learn how to set it up.

The TMZ PC-Programmable MODBUS Temperature Transmitter and Signal Converter provides Analog-to-MODBUS Conversion for a variety of direct signal inputs from a wide array of sensors and analog devices and saves on wiring and installation costs by collecting and concentrating multiple points onto a single MODBUS RTU communication link. The Dual Input model provides even more savings.

The THZ3 and TDZ3 Dual Input Smart HART transmitters simplify your operations with two sensor inputs and advanced features that give you far more control over your temperature measurements. Each sensor is individually selectable and programmable via HART or DTM.

Q. We are looking for a signal isolator. We need an input of 0-5VDC, output 4-20mA and the unit needs to be output loop powered.  What do you recommend?

A. The ECT is available with an input 0-5VDC, you’ll need to specify when ordering. The ECT DIN-style signal isolator, converter, repeater, booster and splitter feature solid metal housings that stand up to continuous, daily rigors of process control and factory automation applications. The 2-wire, output-loop powered ECT operates on 12-42DC. A 4-wire, line powered model is also available if voltage outputs or large output drive capabilities are required.

SIY DIN-style signal isolators can also perform the same function and they are PC configurable. The highly versatile SIY programs to accept a wide range of current or voltage inputs. It outputs an isolated, proportional, 4-20mA signal. This 2-wire (loop-powered) transmitter programs in seconds to handle a wide range of important signal interface applications. If field installation is required for your signal converter, the SIY is also available in a weatherproof or hazardous area enclosure. A configuration cable is required to utilize the PC programming capability of the SIY. Use either a Serial RS232 cable with 9 pin connector or USB cable made by Moore Industries.

Another DIN-style mount option is the MIX. The model MIX is also a 2-wire (loop powered) 2-channel or 4-channel isolator/converter. The 2-channel MIX provides conveniently-located DIP switches for selecting input types of 4-20mA, 0-5V, 1-5V or 0-10V for each channel.

Q. I need to boost a 4-20mA signal to get a Fisher FIELDVIEW DVC6200 to respond to a control signal. What could I use?

Q. On a 4-20mA gas detector, while we replace the cell, the output reverts to 3mA. This causes the device receiving the 4-20mA signal to go into a critical alarm condition and can shut down a critical process. What device do you have that will keep the output at no less than 4mA?

It would also be convenient to have this instrument provide me with a 'relay alarm contact output' when my input goes to 3mA. It can be 24Vdc or 120Vac. It should be in a DIN housing.

A. Moore Industries CPT PC-Programmable Temperature Transmitter and Signal Isolator/Converter CPT/HLPRG/0-20MA/117AC*/-C [DIN] can be used for this application. A configuration cable is required to utilize the PC programming capability. The selected model will have the functions of the signal repeater with an alarm relay output. You can set the alarm fault relay to trigger at your choice of input signal level below 4mA.

The CPT has a menu selection for upper and lower limits. You can set 3.9mA low limit there.

The SPA² upper and lower limits must be defined by setting up a “custom curve” lookup table which (below), in this case, will be 5 points where in = out. By using the custom curve table, the output will not go below the lowest ordered pair or above the highest ordered pair. In this case it will define the lower output limit.

When you need to interface field processes with computer-based systems, readout equipment, and other instrumentation, our temperature transmitterstransmitters sensors and assemblies, isolators and repeaters, alrm trips, remote I/O, service and experience help you do it efficiently, cost-effectively, and more safely than ever with our growing family of Functional Safety solutionss.

The SIL3 capable SLD features a large integral display that shows real-time process status in mA, percent, or any designated 5-character Engineering units (EGU). The latest addition to the Moore Industries’ FS Functional Safety Series products, it is certified by exida® as a SIL3 capable, non-interfering device for use in a safety loop. The SLD is the perfect solution to accurately and reliably display process status in a safety loop, and features the Loop Maintenance Diode Option which allows it to be removed from the safety loop without affecting the integrity of the safety function.  Find out more here.

The SPA² now offers versatile new alarm options that allow the user to set up more specific alarm functions.

• The Band Alarm combines the High and the Low Trip Alarms into one alarm to warn of a process that has left its normal operating conditions.
• The updated rate-of-change alarm now allows the operator to alarm when PV is rising too rapidly, falling too rapidly or if either process condition occurs. 
• The Stuck Input Alarm monitors the input with respect to time and trips when that input hasn’t changed by a user-selected rate (Delta) over a user selected time period (Delta Time).
• The Fault alarm includes: Input Saturation to identify when the input signal exceeds 110% of calibrated input range, an Out-of-Range alarm, and broken wire alarm.
• A Copy Alarm setting allows the user to duplicate the exact setting of any other alarm.

The SPA² provides users the ability to setup the alarm using on-board controls or the company’s free updated PC Configuration Software. 

Each individual alarm trip relay may still be programmed as a high or low limit process alarm or configured for simple on-off control utilizing a deadband range of 0-00%

 An updated manual combines both the TRPG and HLPRG SPA² input versions into a single manual. The new SPA² has the same reliability and quality expected from Moore Industries with the same great features including the ability to accept input signals from transmitters, temperature sensors, resistance and potentiometer devices, and direct millivolt sources.

Moore Industries has released a Rear Terminal Kit for the TDZ3 and STZ HP temperature transmitters. Sometimes very large gauge thermocouple wire is used and when the application requires dual input, fitting two large gauge leads into the same terminal can be problematic or lead to loose connections.

This terminal kit alleviates that by offering large terminal field-side connections for large gauge wire and pre-installed smaller gauge thermocouple wire for the transmitter connection.

The kit is available for thermocouple types J, K, T, E, and N. The downloadable installation sheet available at the link below also includes ordering information. You will need to order the kit for a specific thermocouple type, so be sure to specify which thermocouple you have. The part number format is 209-845x-00, where x is the thermocouple type.

The STZ, part of Moore Industries’ FS Functional Safety Series, is SIL2/3 capable. The STZ Functional Safety Dual Input Smart HART® Temperature Transmitters is an excellent addition for your SIS (Safety Instrumented System). It configures quickly and easily to accept a single or dual input from a wide array of sensors and analog devices:

• 14 RTD Types
• 9 Thermocouple Types
• Resistance and Potentiometer Devices
• Direct Millivolt Sources

Find out more information on the TDZ3 or the STZ or download the available installation document in PDF format.
