Description

The Allen-Bradley 1762-OW8 is a specialized relay output expansion module designed for the MicroLogix 1100, 1200, and 1400 controller families. This module provides eight isolated relay output points, allowing for the control of various field devices such as motor starters, contactors, and solenoid valves. It is engineered to provide flexible switching capabilities for both AC and DC load applications within industrial control systems.

Features

• Eight (8) independent AC/DC relay output channels.
• Organized into two (2) isolated groups of four (4) channels each.
• Compatible with MicroLogix 1100, 1200, and 1400 programmable logic controllers.
• Supports a wide operating voltage range for versatile field device integration.
• Compact design suitable for space-constrained control cabinets.
• DIN-rail or panel mounting options for flexible installation.

Technical Specifications

Installation Guidelines

• Ensure the controller power is disconnected before installing or removing the module to prevent electrical shock or damage to the backplane.
• The module should be mounted in a clean, dry environment within the specified operating temperature range.
• Use shielded cables for output wiring to minimize electromagnetic interference (EMI) in high-noise industrial environments.
• Ensure proper grounding of the DIN rail or panel to maintain system integrity.
• Verify that the load current does not exceed the 2.5 A per-point rating to prevent relay contact degradation.
• Maintain adequate clearance around the module to allow for proper heat dissipation and airflow.

FAQ

What controllers are compatible with the 1762-OW8?

The 1762-OW8 is designed specifically for use with the Allen-Bradley MicroLogix 1100, 1200, and 1400 series controllers.

Can this module handle both AC and DC loads?

Yes, the 1762-OW8 features relay outputs capable of switching both AC (5-265V) and DC (5-125V) loads, making it highly versatile for mixed-voltage applications.

How are the outputs grouped on this module?

The eight outputs are divided into two isolated groups, with four channels in each group, allowing for separate power source configurations if required by the application.
