The Allen-Bradley 1746-OW16 Relay Output Module is a chassis-mounted relay output card for SLC 500 PLC systems, delivering 16 relay outputs to switch AC or DC loads. It enables discrete output control of actuators, motors, solenoids, and other external devices in conveyors, packaging machines, assembly lines, and process equipment. The module is compatible with Allen-Bradley SLC 500 PLCs, with AC/DC-compatible relay outputs and a contact rating suitable for industrial loads; common replacements for this part include the 1746-OW8, 1746-OB16, and 1746-OW4.
