Allen Bradley 1769-IQ16 CompactLogix Compact Digital DC I/O Module

Product Introduction

The Allen Bradley 1769-IQ16 CompactLogix Compact Digital DC I/O Module is a reliable digital input module designed for industrial automation systems requiring accurate monitoring of DC signals. Developed by Allen Bradley, this module enables CompactLogix controllers to interface with field devices such as proximity sensors, push buttons, limit switches, and other DC signal sources.

The 1769-IQ16 module provides 16 digital input points organized into two groups of eight channels each. It supports both sinking and sourcing configurations, allowing flexible integration with a wide range of field devices and control architectures. The module operates within a DC voltage range of 10–30 VDC, making it compatible with common industrial power systems.

Designed for use with CompactLogix PLC platforms, the module converts incoming DC signals into digital data that can be processed by the controller for monitoring, diagnostics, and automation control. Its compact design allows efficient installation within control panels while maintaining reliable operation in demanding industrial environments.

This module is widely used in manufacturing automation, machine control, process monitoring, and industrial safety systems where stable and accurate digital signal acquisition is required.
