Modbus RTU Module MR-DI4, 4 digital inputs, 20–28 V AC/DC

The Modbus module with 4 digital inputs was developed for decentralized switching tasks. It is suitable for detecting potential-free switch states, such as electrical limit switches on ventilation dampers or auxiliary contacts on power contactors. The inputs can be configured using potential-free switches or contacts, as well as voltage inputs. The inputs can be queried via standard registers using a Modbus master. The module is addressed, and the baud rate and parity are set, using two address switches on the front panel or via software. Suitable for decentralized mounting on a TH35 mounting rail according to IEC 60715 in electrical distribution panels. Connection via screw terminals. Also available with spring terminals.
