Schneider Electric's Modicon 140-DDI-353-00 Discrete Input Module is a digital input interface for Modicon PLCs, designed to expand a controller's ability to read binary signals. It accepts discrete on/off signals from field devices such as switches and sensors and converts them into data the PLC uses for logic and control decisions. As part of the Modicon 140-series I/O family, the 140-DDI-353-00 integrates with compatible controllers to support scalable automation configurations.
