The 1769-OW8 (Part Number: 1769-OW8) is a versatile digital relay output module designed for use with Allen-Bradley CompactLogix and MicroLogix 1500 controllers. This module provides eight normally open (N.O.) mechanical contacts, making it a reliable interface for switching both AC and DC loads in industrial environments. The hardware is organized into two isolated groups, with four points per group, allowing for the control of multiple independent power circuits within a single module.
Engineered for flexibility, the 1769-OW8 accommodates a wide range of voltages, from low-level 5V signals up to 265V AC. It features robust dielectric isolation to protect the system backplane from field-side surges and electrical noise. As a standard 1769 module, it occupies a single slot and can be easily mounted on a DIN rail or panel. To ensure proper operation, this module must be placed within eight slots of a compatible 1769-series power supply.
| Specification | Details |
|---|---|
| Channel Grouping | 2 isolated groups (4 points per group) |
| Operating Voltage Range | 5V to 265V AC / 5V to 125V DC |
| Signal Delay | 10 ms maximum for both On and Off states |
| Contact Load Rating | 2.5 Amps per point (maximum) |
| Backplane Current Draw | 125 mA at 5.1V DC / 100 mA at 24V DC |
| Heat Dissipation | 2.83 Watts (maximum) |
| Isolation Voltage | 265V AC working voltage (Reinforced insulation) |
| Dielectric Strength | Tested at 1836V AC for 1 s or 2596V DC for 1 s |

| Physical Dimensions | 118 mm x 35 mm x 87 mm |
The 1769-OW8 is commonly used in applications requiring the control of:
Interposing relays
Solenoid valves
Motor starters
Its ability to handle both AC and DC sources makes it ideal for decentralized control panels where diverse peripheral voltages are present.
What is the difference between the 1769-OW8 and 1769-OW8I?
The standard 1769-OW8 features two groups of four points, whereas the 1769-OW8I provides individual isolation for every single output point. If you need eight different common returns, the "I" (Isolated) version is required.
Can I use this module to switch high-frequency loads?
Due to the mechanical nature of relays and a 10ms switching delay, this module is not suitable for high-speed PWM or high-frequency cycling. For those applications, a solid-state (triac or transistor) output module is recommended.
