Allen-Bradley 1762-IQ32T 32-Point DC Input Module

Product Overview

The Allen-Bradley 1762-IQ32T is a high-density discrete input module. It adds thirty-two input channels to MicroLogix controllers. This module supports 24V DC sink/source wiring. It works with MicroLogix 1100, 1200, and 1500 systems. The module comes in four isolated groups of eight channels each. This design ensures reliable signal handling in industrial environments.

Application Scenarios

This input module extends I/O capacity for PLC-based automation. Use it in manufacturing lines, packaging machines, and material handling. It suits applications requiring many digital inputs. Examples include push buttons, limit switches, and proximity sensors. The group isolation protects against ground loops. This makes it ideal for noisy industrial settings.

Technical Specifications

The 1762-IQ32T operates at 10 to 30 VDC. Nominal input voltage is 24 VDC. Minimum ON-state voltage is 10 VDC. Maximum OFF-state voltage is 5 VDC. Signal delay is 8 ms for ON and OFF transitions. Backplane current draw is 170 mA at 5 VDC. Heat dissipation ranges from 5.4 to 6.8 watts. The module measures 90 x 40.4 x 87 mm and weighs 200 grams.

Isolation withstands 1200 VAC for 2 seconds. Working voltage is 75 VDC per IEC Class 2. Input channels are grouped: channels 0-7, 8-15, 16-23, and 24-31. Each group provides separate isolation. The module uses a single status LED for power indication.

Installation & Maintenance Guide

Always avoid electrostatic discharge. Remove power before installation. Mount the module on a DIN rail. Use the finger-safe terminal cover for wiring. Connect field devices to the correct group terminals. Configure input channels in your controller software. For troubleshooting, check the power LED. Stand away from equipment during live checks. Ensure safety circuits are wired in series to the master relay.
