Allen-Bradley 871CDM1NP7E2 Digital Input Module delivers discrete-input sensing for compatible Allen-Bradley PLC systems. As a digital input module, it reads on/off signals from field devices such as switches and proximity sensors and translates them into the controller’s input image. In typical automation setups, it supports multiple input channels and provides the interface needed for real-time state changes to drive logic. This module is used within broader Allen-Bradley control architectures to expand a PLC’s capability to observe process conditions and safety interlocks.
