Product details

The Omron CS1W-MD561 packs 32 digital inputs and 32 solid-state outputs into one backplane-mounted module for the CS Series PLC rack. Rated for CE, cULus, Lloyd, and NK approvals, it shares the same physical footprint and rectangular connector termination as the CS1W-MD262 sibling.

Bolts onto the CS Series backplane. Rectangular connector for I/O wiring — spring-cage or screw? Not detailed, but field wiring typically follows the earlier MD262 pinout. Verify with the existing install to avoid re-termination.

Frequently asked questions

What is the closest functional second-source to CS1W-MD561?

The CS1W-MD262 is functionally identical with the same 32 digital inputs and 32 solid-state outputs, same backplane mount and rectangular connector. The key difference is approval marks: MD561 has cULus, MD262 has CSA and UL.

What is CS1W-MD561's listed type?

Input, Output (I/O) Module.

What series does CS1W-MD561 belong to?

CS1W series.

Will CS1W-MD561 drop into a panel that was specified around CS1W-MD262 without rewiring?

Yes, direct fit. Same backplane mount, same connector, same I/O count. Approval difference (cULus vs CSA/UL) is the only variant — verify which mark your panel requires.
