The MR-DI4 IP65 Modbus RTU with external display is suitable for detecting potential-free switch states, for example electrical limit switches on vent valves or auxiliary contacts of power contactors. The inputs can be operated by means of potential-free switches or contacts or used as voltage inputs. The device has two externally connectable display modules.
