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.","metaTitle":"CS1W-MD561 I/O Module, 32DI/32DO, Active","metaDescription":"Active Omron CS1W-MD561 I/O module: 32 digital inputs, 32 solid-state outputs.
