Product Description

Allen-Bradley 1771-OW16-B PLC-5 Relay Output Module for AC/DC Loads

The Allen-Bradley 1771-OW16-B is a 16-point electromechanical relay contact output module designed for the 1771 PLC-5 I/O platform. It provides isolated switching of AC and DC loads using mechanical relay contacts powered directly from the 1771 chassis backplane.

Relay-Based Output Architecture

  • Sixteen total relay outputs arranged in two isolated groups of eight
  • Eight normally open contacts and eight selectable NO or NC contacts
  • Supports 24–250 VAC and 24–150 VDC switching
  • Individual commons per output for channel isolation

Industrial Electrical Performance

Each output is independently isolated from logic circuitry, allowing safe control of mixed-voltage loads. The module supports resistive, capacitive, and inductive loads when external surge suppression is applied, preserving relay life and system stability.

PLC-5 System Applications

  • Motor starters and contactor control
  • Solenoid and actuator switching
  • Industrial pilot device control
