Allen-Bradley 1756-IA16 16Pt AC Input Module 1756IA16

Description:

The Allen-Bradley 1756-IA16 is a 16-point AC digital input module designed for ControlLogix automation systems to monitor 120V AC discrete input signals from field devices. It interfaces pushbuttons, selector switches, limit switches, and relay contacts to Logix-based controllers through the ControlLogix backplane. Commonly installed in industrial control panels, motor control centers, packaging equipment, and automated production lines, this module expands AC input capacity within high-performance control architectures. Maintenance teams and system integrators use this module for system expansion, replacement of failed input cards, retrofit projects, and maintaining ControlLogix-based automation systems.

Applications:

The 1756-IA16 AC input module is used to receive 120V AC signals from field devices in manufacturing facilities, conveyor systems, processing equipment, and material handling installations. It is widely applied where dependable AC discrete input monitoring is required for machine interlocks, operator controls, and system status feedback within industrial automation environments.
