Description
About the XPSMCM
About the XPSMCM
The Schneider Electric XPSMCMRO0004DA is a Modicon MCM safe relay output expansion module with 4 guided-contact safety relay outputs (4 NO, 6 A) plus 8 solid-state diagnostic status outputs and 4 start/restart interlock inputs. It reaches category 4, PLe per ISO 13849-1 and SIL 3 per IEC 61508, and connects to the XPSMCM controller through the backplane expansion bus.

Selection Notes
Choose the XPSMCMRO0004DA over the XPSMCMER0004 when the control system needs per-channel diagnostic feedback — its 8 solid-state status outputs report individual relay channel states back to the PLC, which the simpler ER0004 does not provide. It connects via the backplane expansion bus rather than hard-wiring to the OSSD, so it must sit in a slot on the same rail segment as the XPSMCM base unit. The 6 A, 4 NO contact set matches the ER0004 electrically, so the choice between the two comes down to whether the application needs that diagnostic visibility.
