EHELP: Application for an Analog Splitter

EHELP: Application for an Analog Splitter

Q. I have an application that requires an analog splitter. The single input signal to the splitter comes from a transducer, and the transducer requires loop power. The two outputs are going to an active analog monitoring card on a PLC, which provides power to the connected 4-20mA signals. Is the ECT what I need?

Announcing the SFY Functional Safety Frequency-to-DC Transmitter with Display and SIL 3 Capability

Announcing the SFY Functional Safety Frequency-to-DC Transmitter with Display and SIL 3 Capability
Moore Industries is proud to announce the new SFY Functional Safety Frequency-to-DC Transmitter with display including SIL 3 capability. The 2-wire (loop-powered) SFY is ideal for use in your Safety Instrumented System (SIS) in a wide range of process and factory automation monitoring applications and as part of the FS Functional Safety Series providing reliable and accurate monitoring of frequency or pulse signals in SIS. The SFY is approved for single use in SIS up to SIL 2 and in a redundant architecture (1oo2, 2oo3, etc.) up to SIL 3.

EHELP: What are the advantages and limitations of HART protocol or an instrument with embedded MODBUS communication?

EHELP: What are the advantages and limitations of HART protocol or an instrument with embedded MODBUS communication?

Q: What are the advantages and limitations of HART protocol or an instrument with embedded MODBUS communication? How many instruments can the HCS interface in the same loop? Are we able to read/write the five instruments at the same time using HART?

EHELP: STA Analog Output Protection

EHELP: STA Analog Output Protection
Q:  In specifying the Moore STA / HLPRG / 3PRG / U / -AO [DIN] our end user has a concern about electrical protection for the analog output. The desire is to use 4-20mA Output Loop Voltage sourced by DCS for the AO; however, this voltage may fault at up to 132 VAC. Should our design add fuse protection in the external voltage circuit upstream of the STA to protect it from these surges? Or does the STA include features that protect it from these faults?
