Allen-Bradley 1746-OW16 Relay Output Module SLC 500 1746OW16

Description:

The Allen‑Bradley 1746‑OW16 relay output module is used in industrial automation systems to provide discrete relay outputs for controlling field devices. It is commonly installed in SLC 500 PLC racks and control panels to interface programmable logic controller outputs with actuators, lamps, and control devices. Maintenance teams and system integrators use this module for I/O expansion, machine control upgrades, and replacement of failed or aging output modules.

Applications:

The Allen‑Bradley 1746‑OW16 relay output module is widely used in factory and process automation environments requiring reliable discrete output switching. It is commonly found in conveyor systems, packaging machinery, assembly lines, material handling systems, motor control circuits, and building automation where PLC logic switches relays, solenoids, pilot lights, and contactor coils as part of automated control.
