Product Summary

The 1762-OW8 relay output module expands your MicroLogix system with eight reliable switching points. Engineers use this module to control contactors, solenoids, and pilot indicators. Its rackless design simplifies installation and reduces spare parts inventory for your facility.

Why Procurement Teams Choose the 1762-OW8

Procurement managers gain flexibility with this modular output solution. The 1762-OW8 supports both DIN rail and panel mounting for diverse cabinet layouts. Its broad voltage range from 5 to 265 Volts AC handles global power standards.

This unit eliminates the need for a separate backplane or chassis. You connect it directly to your MicroLogix 1100, 1200, or 1400 controller via the supplied ribbon cable. This design reduces overall system cost and complexity.

Each of the eight output points handles a continuous current of 2.5 A. The module supports a maximum current of 16 A per module and 8 A per common. These ratings suit a wide range of industrial loads.

The module features two isolated output groups of four channels each. This isolation protects your controller logic from faults on different load circuits. It also simplifies troubleshooting and maintenance.

The signal delay for ON and OFF transitions is a consistent 10 ms. This predictable response ensures reliable timing for your discrete control sequences. Use it for alarm panels, VFD start commands, and motor starters.

Installation Guide for the 1762-OW8 Module

Mount this expansion module on a standard DIN rail per EN 50022 specifications. Use rails that are 35 x 7.5 mm or 35 x 15 mm for a secure fit. Secure the module with end anchors in high-vibration environments.

For extreme vibration, choose panel mounting instead of DIN rail. This method provides a rigid connection that prevents mechanical stress. Always keep debris away from the module’s interior during installation.

Connect the module to your MicroLogix base controller using the provided ribbon cable. This cable links the expansion bus between adjacent modules. Place this module at least six modules away from the host power supply for stable operation.

Configure the hardware in your programming software before operation. You must introduce the module in the device configuration to enable its channels. This step ensures proper addressing and functionality.

Wire your load devices to the normally-open relay contacts. Each output group has a common terminal for its four channels. Verify the voltage and current ratings of your specific load before connection.

Use this module to drive magnetic contactors, relay coils, and solenoid valves. It also signals RUN or START commands for variable frequency drives and motor starters. Common applications include pilot lamps, sirens, buzzers, and indicator panels.
