The MB-DIO4/2-IP 230 V module in an IP65 housing with 4 digital inputs and 2 relay outputs is designed for decentralized switching tasks. Suitable for e.g. incorporating light switches and window contacts in a room and switching light strips or using them to control blinds. Motor-operated actuators (e.g. ventilation or fire dampers) can be controlled. Depending on the operating mode, the module can be switched or queried with Modbus standard registers or with BACnet objects. The relay outputs are equipped with switches for manual control. The operating mode, bit rate and parity are set using two rotary switches. Operating mode, bit rate and parity can also be set via software. For controlling up to two actuators, e.g. fire dampers, connection options for actuators with open connection cables with pluggable push-in technology, supply voltage is also switching voltage, relay output suitable for inrush current 65 A < 20 ms (NO), continuous current 6A, total current 8 A, generous space for installation - no additional distribution box required
