Frequently Asked Questions

Question: How do I change a channel from 2-wire to 4-wire transmitter configuration?

Answer: You must configure the physical setting pins located on the side of the module for each independent channel.

Question: What happens to the input resistance when the system loses power?

Answer: The input resistance shifts to 500 kΩ or larger to protect the field loop instrumentation.

Question: Can this module supply power directly to a field transmitter?

Answer: Yes, the built-in transmitter power supply provides 19.0 V or higher for 2-wire current loops.

Question: Does this module require specialized software configuration for basic operation?

Answer: You configure the module parameters within the standard Yokogawa system engineering environment tool.
