Schneider Electric XPSMCMC10804 Modicon MCM Safety Controller 8 Inputs 4 Outputs 24 V DC Safety PLC

The Schneider Electric XPSMCMC10804 is a Modicon MCM safety controller CPU with 8 safety digital inputs and 4 OSSD safety outputs, supplied at 24 V DC through captive screw terminals. It monitors machine safety functions such as emergency stop, guard interlocking, light curtains and two-hand control, and expands over its backplane bus to up to 14 I/O modules for larger safety architectures.

Selection Notes

Choose the XPSMCMC10804 over the 2-output controller variant when a machine needs 4 independent OSSD output pairs from one CPU - for example separate zones each with their own contactor or drive enable - rather than relying only on expansion modules for extra outputs. Both controllers share the same 8-input count and reach Category 4 / PL e per ISO 13849-1 with SILCL 3 per IEC 62061, so the choice comes down to how many safety outputs the base CPU must drive directly. Configuration runs through EcoStruxure Machine Expert software over the Mini USB port, and the system scales to up to 14 backplane-connected expansion modules - input, output or non-safe diagnostic modules - when the machine's safety-function count outgrows the CPU's own 8/4 I/O.

Applications

The XPSMCMC10804 fits machines with several independent safety-output zones - multi-station guarding, light-curtain-protected cells with separate drive enables, or two-hand control stations - where each zone needs its own OSSD pair rather than sharing outputs across the cell.
