MR-DI10 Modbus RTU module with 10 digital inputs

The Modbus module with 10 digital inputs has been developed for decentralized switching tasks. It is suitable for detecting potential-free switching states, for example, electrical limit switches on exhaust valves or auxiliary contacts of power contactors. The inputs can be used as contact or voltage inputs. The inputs can be scanned by means of standard registers via a Modbus master. The module address, bit rate, and parity are set with 2 rotary switches on the front or via software. Suitable for decentralized mounting on DIN rail TH35 according to IEC 60715 in electrical distribution cabinets.
