This module provides 32 digital input points, which can be used to monitor the status of discrete devices such as switches, sensors, and push buttons. Each input point can handle both AC and DC voltage signals. The 1769-IQ32 module offers flexibility in wiring as it supports 2-wire and 3-wire devices.

The module requires a compatible PLC system chassis to function, such as the Allen-Bradley 1769 CompactLogix or MicroLogix 1500 chassis. It connects to the chassis via a removable terminal block, making it easy to install and replace.
