Industrial B873-011 Programmable Logic Controller Input Module, also known as Gould B873-011 AEG Modicon Input Module, is a digital input component for Modicon-compatible PLC systems. It receives external signals from sensors and switches and feeds them into the PLC for processing in industrial automation setups. The B873-011 designation ties this module to Gould/AEG Modicon PLC architectures and identifies its place within the controller’s I/O configuration.
