MR-DI4-IP65 Modbus RTU, with external display

The Modbus module in a surface mounting housing with 4 digital inputs was developed for decentralized switching tasks. It is suitable for detecting potential-free switch states from electrical limit switches and their external status display such as fire dampers or vent valves. The inputs can be operated by means of potential-free switches or contacts or used as voltage inputs. The inputs can be scanned by means of standard registers via a Modbus master. Module address, bit rate and parity are set with two rotary switches or by software.The device has two externally connectable display modules.
