The MR-F-DI4 is a Modbus RTU module that is suitable for decentralised switching tasks in building and automation technology. It has four digital inputs that can be used to detect potential-free switching states, such as limit switches or auxiliary contacts. The inputs can be operated as both contact and voltage inputs. The inputs are requested via standard registers using a Modbus master (e.g. a COMTRAXX device). Addressing and setting the bit rate and parity can be carried out using front switches.
