Allen-Bradley 1762-OB32T Solid State Output Module

Product Overview

The Allen-Bradley 1762-OB32T is a high-density solid-state output module designed for use with MicroLogix controllers. This module provides 32 output channels arranged in two isolated groups of 16 channels each. It delivers a nominal output voltage of 24VDC with an operating range of 10.2 to 26.4VDC. Each channel can handle up to 0.5A continuous current at 60°C, with a group maximum of 2.0A and a module maximum of 4.0A. The <a href="https://www.petroautotech.com/allen-bradley-1762-OB32T-32-point-output-module/" title="Allen-Bradley 1762-OB32T 32-Point Output Module" rel="noopener">1762-OB32T features a robust isolation rating of 1200V AC for 2 seconds, ensuring reliable operation in industrial environments. Its solid-state design offers fast switching with 0.5ms turn-on and 4.0ms turn-off delay for resistive loads. This module supports source wiring and is ideal for energizing indicating lights, solenoid actuators, small DC motors, and other low-power loads.

Application Scenarios

The 1762-OB32T is commonly used in industrial automation systems where multiple DC loads need to be controlled from a MicroLogix PLC. Typical applications include conveyor control, packaging machinery, material handling, and assembly line stations. The module is suitable for switching indicator lights, alarms, solenoid valves, and small DC motors. Due to its high channel count and isolated groups, it is ideal for applications requiring separation of different load types or voltages. It is designed for Pollution Degree 2 environments and can operate at altitudes up to 6562 feet without derating. The module must be installed in a flame-retardant enclosure with a tool-accessible interior.

Technical Specifications

Installation & Maintenance Guide

Before installing the 1762-OB32T, ensure the controller power is off. Mount the module securely in the MicroLogix chassis. Connect wiring according to the source wiring configuration, respecting the channel groups and isolation. Use 22 to 26 AWG wire and tighten terminals to the specified torque. Ensure the enclosure meets flame retardancy standards (5VA, V2, V1, V0). Keep the interior tool-accessible only. During maintenance, inspect for loose connections, signs of overheating, and verify output currents do not exceed ratings. Clean with a dry cloth. No periodic calibration is required. Refer to the user manual for detailed troubleshooting.
