The Modbus module with 10 digital inputs was developed for decentralized switching tasks. It is suitable for recording potential-free switch states, e.g. electrical limit switches on ventilation flaps or auxiliary contacts on power contactors. The inputs can be operated as contact or voltage inputs. The inputs can be queried via a Modbus master using standard registers. The module is addressed and the bit rate and parity are set using 2 address switches on the front or via software. Suitable for decentralized installation on TH35 mounting rails in accordance with IEC 60715 in electrical distribution boards. Connection with screw terminals
