RLY relay modules were frequently added to the UNT controller's binary outputs. You can reuse RLY relay modules when you replace the UNT with an FEC or CGM. You must wire each RLY relay module to one FEC or CGM binary, or to one configurable output (configured for binary output mode). If both relays on one RLY relay module are used, you must configure the FEC or CGM controller outputs identically. Alternatively, you can replace RLY relay modules with IOM models with onboard relay outputs.

Note: Refer to M4-CG Series General Purpose Application Controller Installation Guide (Part No. 24-10143-01698) for information on the CGM controller input and output locations.
