Allen-Bradley 1756-IA16 ControlLogix 16-Point AC Input Module

Product Overview

The Allen-Bradley 1756-IA16 is a digital AC input module for the ControlLogix platform. It provides 16 input points for 120V AC signals. This module operates on a voltage range of 74 to 132V AC. It is ideal for monitoring discrete sensors and switches in industrial environments. The module uses a 20-pin removable terminal block for wiring. It supports a 1756-TBNH or 1756-TBSH housing.

Application Scenarios

This input module works well in factory automation and process control systems. Use it to read signals from push buttons, limit switches, and proximity sensors. It is common in manufacturing lines, packaging machines, and material handling systems. The 1756-IA16 can handle high-voltage AC inputs safely. It fits into any standard ControlLogix chassis.
