Allen-Bradley 1746-OW8 SLC 500 Relay Output Module

Allen-Bradley 1746-OW8 is an eight-channel relay output module designed for SLC 500 programmable controllers. It provides eight relay contacts used to switch external loads from the 1746 I/O backplane, with four common terminals organizing the outputs for straightforward wiring of multiple devices.

• Eight relay contact outputs
• Four common terminals
• Load voltage range: 5–265 VAC or 5–125 VDC
• Part of the SLC 500 family for plug-in installation in AB chassis

Typical applications include energizing solenoids, indicator lamps, and other field devices while keeping the PLC circuitry isolated from high-power loads. The OW8 is compatible with standard SLC 500 wiring practices and backplane communication, enabling reliable discrete switching in industrial control systems that require dependable relay contacts and modular expandability without inserting load power into the controller's circuitry.
