Allen-Bradley 1769-IQ32T CompactLogix 32-Point 24V DC Sink/Source Input Module

Product Description

The 1769-IQ32T (1769-IQ32T) is a high-density discrete input module engineered for Allen-Bradley CompactLogix and MicroLogix 1500 controller systems. It provides 32 digital input points, allowing engineers to interface with a large volume of 24V DC field devices—such as proximity sensors, limit switches, and push buttons—while occupying minimal rack space.

Designed with a bipolar architecture, the 1769-IQ32T (1769-IQ32T) supports both sink (NPN) and source (PNP) wiring configurations, providing maximum flexibility for diverse sensor types. To ensure system reliability, the module features integrated optical isolation, which safeguards the controller backplane from electrical transients and industrial noise. This high-density module is specifically optimized for I/O-intensive applications where panel space is at a premium and cost-per-point efficiency is a priority.
