EHELP: Is There a Solution to Pass Hart Data Through an Isolator to My DCS?

EHELP: Is There a Solution to Pass Hart Data Through an Isolator to My DCS?
Q. I want to share a critical pressure signal with my DCS that is now part of our safety instrumented system (SIS) and have a two part question. First, do your isolators pass the HART diagnostic data that comes from my SIS smart pressure transmitter? Second, if there is a total failure of the pressure transmitter, where will the output of the isolator go to that is feeding my DCS?

EHELP: Can the ECT-DIN, be configured for a 4-20mA input and 4-12mA split range output?

EHELP: Can the ECT-DIN, be configured for a 4-20mA input and 4-12mA split range output?

Q. Can the ECT-DIN, configured for 4-20mA input and 4-20mA output, be calibrated to give 4-12mA output when the input is 4-20mA so that the output is 1/2 the input? We have a radio I/O signal that is scaled to 4-20mA for 0-65, 535raw units. When sent to the PLC over Modbus, it can't be read properly since the maximum register value size for the PLC is limited to 32767.

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.
