Allen-Bradley 1769-OW8 CompactLogix AC/DC Relay Output Module

Product Overview

The 1769-OW8 is a versatile digital relay output module for Allen-Bradley CompactLogix and MicroLogix 1500 systems. Featuring eight normally open (N.O.) relay contacts, it provides a robust interface for switching AC and DC loads, including motor starters, solenoid valves, and indicator lights. Mechanical contacts offer high voltage flexibility and low on-state resistance, suitable for diverse industrial control environments.

Technical Specifications

Functional Design and Reliability

• Two separate common terminals allow switching of different voltages or phases.

• Each group of four outputs is isolated for added safety.

• Relay contacts rated for high-cycle industrial use; RC snubber (AC) or diode (DC) recommended for inductive loads.

• Compatible with 1769-PA2, 1769-PB2, 1769-PA4, and 1769-PB4 power modules.

• Integrates with CompactLogix 5370 controllers or 1769-AENTR Distributed I/O adapters.

Common Technical Questions

Can I mix AC and DC loads on the same module?
Yes, if separated by isolated groups. For example, Group 1 (outputs 0–3) can switch 120V AC, and Group 2 (outputs 4–7) can switch 24V DC.

What does the Power Supply Distance Rating of 8 mean?
The module must be within 8 slots of the system power supply to ensure adequate voltage and current for reliable relay operation.
