Allen-Bradley 1746-OW8 PLC Module

Allen-Bradley 1746-OW8 is an eight-channel relay output module designed for the SLC 500 family of programmable logic controllers. It provides eight discrete relay contacts that switch field loads, suitable for AC or DC operation. The outputs are rated for 5–265 V AC or 5–125 V DC, enabling direct control of devices such as motors, solenoids, pumps, indicators, and other I/O from a compatible 1746 processor. The module plugs into the SLC backplane to expand the controller’s discrete output capability in legacy Rockwell Automation installations, and is cataloged as SLC50x 8DO, Series A, working with standard 1746-series CPUs for common automation tasks requiring reliable relay switching. With eight outputs on a single module, it offers a compact solution for isolating and controlling multiple field devices from a single SLC 500 chassis.
