Allen-Bradley 1771-IA2 is a 16-point DC input module in the 1771 I/O family that interfaces external DC signals with a PLC. It provides 16 discrete input channels that feed the associated controller via the 1771 I/O bus. Designed for use in compatible 1771 I/O racks, this module expands digital input capacity in industrial automation systems. Typical applications include wiring sensors, pushbuttons, and other DC signaling devices to monitor and respond to real-time conditions.
