8 relay outputs on the CS-series backplane
The Omron CS1W-OC201 is an output module that provides 8 relay outputs for the CS Series PLCs, mounted directly on the backplane and terminated via screw terminals. Relay outputs are the right call when you need isolation between the PLC and field loads — solenoids, contactors, small motors in a cement plant or conveyor line — and don't need the switching speed of a transistor output.
Approvals and deployment context
Carries CE, cULus, Lloyd, and NK approvals — so it's accepted in European, North American, and marine (Lloyd's, Nippon Kaiji Kyokai) installations without extra certification paperwork. Backplane mount means it slots into the CS-series rack alongside CPU, power supply, and I/O modules — no DIN rail or panel wiring for the module itself, just the field wiring to the screw terminals.
