Allen Bradley 1769-IA16 CompactLogix AC Digital Input Module

Product Introduction

The Allen Bradley 1769-IA16 CompactLogix AC Digital Input Module is a high-performance input module designed for the CompactLogix 1769 I/O platform. It provides 16 channels of AC digital input, allowing CompactLogix controllers to monitor multiple AC field devices simultaneously.

The module supports a wide voltage range of 79–132 VAC and standard AC frequencies (47–63 Hz), making it compatible with most industrial control systems. It is engineered to convert incoming AC signals from sensors, switches, and other field devices into digital signals that can be processed by the PLC.

With low current draw and efficient internal circuitry, the 1769-IA16 ensures minimal impact on system power while providing reliable signal detection. The module integrates seamlessly into CompactLogix backplanes and communicates via the internal bus to provide real-time input monitoring. It is ideal for use in industrial automation, machine control, and process monitoring applications where accurate and rapid detection of AC input signals is required.
