Allen-Bradley 1762-OW16 MicroLogix Relay Output Module

Product Overview

The Allen-Bradley 1762-OW16 is a MicroLogix relay output expansion module that provides sixteen normally open relay contacts. This **1762-OW16** module operates on both AC and DC voltages, covering a range of 5-265VAC and 5-125VDC. Each output point handles a continuous current of up to 2.5A. The module features two isolated groups, each with eight channels, allowing flexible connection to different voltage levels. It enhances the output capacity of MicroLogix 1100, 1200, and 1400 PLCs. The module dissipates 6.1 W of heat and has an IP20 enclosure rating.

Application Scenarios

This relay output module is ideal for industrial automation applications that require switching of inductive or resistive loads. Typical uses include controlling motors, solenoids, valves, and lighting systems. The isolated groups enable simultaneous control of loads with different voltage ratings. Factories, packaging lines, material handling systems, and process control facilities rely on the **1762-OW16** for reliable output expansion. The module is often deployed in assembly lines, conveyor systems, and machine tool control.

Technical Specifications

The 1762-OW16 has sixteen relay outputs arranged in two groups of eight. The relay contacts are rated for 24-125 VDC and 120-240 VAC continuous current per point of 2.5 A at AC and 1-2 A at DC (2 A for 125 VDC, 1 A for 24 VDC). The continuous current per common is 8 A, and per module is 16 A. Maximum controlled load is 1440 VA. Signal delay is 10 ms both on-off and off-on. The module draws 140 mA at 5 VDC and 180 mA at 24 VDC from the backplane. Minimum on-state current is 10 mA. Dimensions are 90 x 40.4 x 87 mm (including tabs 110 mm height). Weight is 0.63 lb. Mounting is DIN rail or panel. The module is compatible with MicroLogix 1100 (up to 4 modules), 1200 (up to 6 modules), and 1400 (up to 7 modules) controllers.

Installation & Maintenance Guide

Install the module on a DIN rail or panel using the provided mounting tabs. Connect it to the MicroLogix base controller via the expansion bus connector. Ensure proper isolation between Group 0 (outputs 0-7) and Group 1 (outputs 8-15). For inductive loads, install surge suppressors across the load to protect relay contacts. Follow wiring guidelines in the user manual. Avoid electrostatic discharge during handling. Maintain airflow around the module to prevent overheating. Periodically check connections and replace the module if contacts wear.
