Description

Allen-Bradley 1771-IDC 120V Isolated AC/DC Input Module PLC-2 PLC-3 1771

This is a 16-input isolated AC/DC input module designed for Allen-Bradley PLC-2 and PLC-3 programmable logic controllers. The module accepts 120V AC or DC signals and provides electrical isolation for each input channel.

Specifications & What's Included

  • Model: 1771-IDC
  • 16 isolated inputs at 120V AC/DC
  • Compatible with Allen-Bradley PLC-2, PLC-3, and 1771 I/O chassis
  • Card/module form factor for 1771 series slot mounting
  • UL Listed (when used with listed system)
  • Module only; no accessories included

Applications

The 1771-IDC series was commonly used in industrial automation and process control systems from the 1980s through early 2000s. It functions as the input interface between field devices and the PLC processor, converting real-world AC/DC signals into digital data. This module is typical for monitoring discrete signals such as limit switches, pushbuttons, and sensor outputs in manufacturing and facility automation environments.

Condition: Used
This Allen-Bradley 1771-IDC 120V Isolated AC/DC Input Module has been inspected and appears to be in good condition. It was pulled from a working environment where it was previously in service. The module housing shows normal wear consistent with industrial use, and the PCB and connectors appear intact. The terminal block and wiring label are present.
