Q&A
- Q: Can this module mix RTD and Thermocouple inputs?
- A: Yes, each channel is independently programmable for different sensor types.
- Q: Does the 146031-01 include the internal barriers?
- A: This part number refers to the main processor module; internal barriers are part of specific I/O modules.
- Q: What happens if a sensor wire breaks?
- A: The module features “Not OK” status logic that detects open circuits and prevents false trips.
