The Omron CJ1W-OD201 is a 8-point solid-state output module for the CJ Series PLCs. It mounts on DIN rail, terminates with screw terminals, and switches outputs through transistor circuits — no relay wear, so it handles high-frequency or fast-cycle loads better than a mechanical relay pack.
The CJ1W-OD201 carries CE, cULus, Lloyd, and NK approvals — those cover the usual industrial and marine certifications. No RoHS/REACH statement is listed, but for a standard output module in this class, the compliance paperwork is generally available on request.
