CJ1W-OC201 8-Point Relay Output Unit Independent Contacts 2A | Omron

The Original New Omron CJ1W-OC201 is an 8-point relay output unit for the SYSMAC CJ series programmable logic controller (PLC) platform, featuring independent relay contacts for versatile AC/DC load switching. Each of the 8 outputs is electrically isolated from the others, allowing different voltage levels to be switched simultaneously within a single module. Rated at 2 A per point with a maximum switching capacity of 250 V AC / 24 V DC, this unit provides reliable control for solenoids, contactors, motors, and indicator lights. The removable screw terminal block simplifies wiring and maintenance, while the 15 ms max response time ensures dependable performance in industrial automation applications. Part of the CJ-series Basic I/O Unit family, it is fully compatible with CJ1, CJ2, and NJ series CPU units.
