Product Details
Specifications provided for reference. Verify critical details against official manufacturer documentation before installation.
Product Overview
The Allen-Bradley 1771-IAN is a Digital AC Input Module in the PLC-5 1771 series. It accepts 85-138 V AC at 50/60 Hz and provides 32 discrete input channels (4 groups of 8) to the PLC control system. It installs in a 1771 I/O chassis, reporting input states via optoelectrical isolation and LED indicators. Typical applications include discrete AC interface for sensors, pushbuttons, limit switches, and pilot lights in manufacturing and process control environments.
