1746-OW8 | Allen-Bradley SLC 500 Eight-Channel Relay Output Module

Allen-Bradley · HMIs & Displays

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.     Technical Specifications Condition New/Never Used Surplus Brand Allen-Bradley Category PLCs/Machine Control Part Number 1746-OW8 Subcategory Digital Contact Output Module Manufacturer Rockwell Automation Series SLC 500 Module Type Relay Output Module Outputs 8 normally open relay contacts Operating Voltage 5–265 VAC or 5–125 VDC Number of Groups 2 Points per Group 4 Current per Output (120 VAC) 1.5 A Current per Output (24 VDC) 1.2 A Continuous Current per Group 8 A Continuous Current per Module 16 A Backplane Current (5 VDC) 85 mA Backplane Current (24 VDC) 90 mA Signal Delay 10 ms ON / 10 ms OFF Step Response 60 ms in / 2.5 ms out Heat Dissipation 3.7 W (0.138 W per point) Operating Temperature –25°C to +60°C Storage Temperature –40°C to +85°C Humidity Rating 5–95% non-condensing Vibration Rating 2 G (10–500 Hz) Shock Rating 30 G Enclosure Type Open-style Environmental Rating Pollution Degree 2 Application Industrial relay output switching     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.
