Product Description

Allen-Bradley 1771-IAD 16-Channel AC/DC Input Module for PLC-5 Systems

The Allen-Bradley 1771-IAD is a digital AC/DC input module engineered for PLC-5 control systems using the 1771 I/O platform. It provides reliable monitoring of discrete field signals in industrial automation environments.

16-Channel Discrete Input Capability

  • Sixteen individual digital input channels
  • 120V AC/DC voltage category
  • Accepts AC or DC input signals within the specified operating range
  • Front-panel status indicators for each input channel

Industrial Module Architecture

The 1771-IAD installs directly into compatible 1771 I/O chassis and draws power from the backplane. Selectable input signal delay filtering supports stable signal processing in electrically noisy environments while maintaining accurate state detection.

Typical Applications

  • Monitoring pushbuttons, limit switches, and selector switches
  • Interfacing relay and contactor auxiliary contacts
  • Discrete input acquisition in PLC-5 automation systems
