Product Description P/N: 1746-OW8
Description
The Allen-Bradley 1746-OW8 is an SLC 500 relay output module that provides eight normally open contact outputs for AC or DC load switching. Operating across a wide voltage range of 5–265 VAC or 5–125 VDC, it is divided into two groups of four channels per common for flexible wiring. This module enables reliable control of external devices without interposing relays, making it ideal for mixed-voltage industrial applications.

Information About 1746-OW8
The 1746-OW8 is part of the SLC 500 I/O family and is designed to interface relay-driven loads within automation systems. Its configuration includes eight channels grouped into two commons, allowing separate voltage types or source supplies across channel groups. The module supports industrial temperatures, meets vibration and shock requirements, and mounts in any slot of an SLC 500 chassis or remote I/O rack. Typical applications include contactor control, valve actuation, pilot devices, and equipment requiring mechanical relay isolation.
Key Features
- Eight N.O. relay outputs: Supports AC or DC load switching without external relays.
- Wide operating voltage range: Handles 5–265 VAC or 5–125 VDC loads.
- Two output groups: Four channels per common for flexible wiring configurations.
- Compatible with SLC 5/01–5/05: Works in both local and remote I/O chassis.
- Industrial durability: Withstands 2G vibration and 30G operational shock.
- Class I, Division 2 rated: Suitable for hazardous industrial locations.
- Fast response: 10 ms ON/OFF signal delay at resistive load.
The 1746-OW8 delivers the reliability and precision required for robust relay output control in SLC 500 automation systems.
