# Digital Input Module
Digital Input Module is used to monitor the status of discrete signals such as contactors, relays and others. ENP-DI7 Module can work in wet or dry contact modes (set by the jumper inside the module). The Digital Input Module sends the collected data to the Enapter Gateway and Cloud via secure wireless connection.
