The MB-DIO4/2-IP 230 V module in an IP65 housing with 4 digital inputs and 2 relay outputs has been developed for decentralized switching tasks. It is suitable, for example, for housing light switches and window contacts in a room, for switching light strips or for blind control. Motorized actuators (e.g., ventilation or fire dampers) can be controlled. Depending on the operating mode, the module can be switched or queried with standard Modbus registers or with BACnet objects. For manual control, the relay outputs are equipped with switches. The settings for operating mode, baud rate, and parity are made via two rotary switches. Operating mode, bit rate, and parity can also be adjusted via software.

Technical Features

• for controlling up to two actuators, e.g., fire dampers
• Connection options for actuators with open connection lines using plug-in push-in technology.
• The supply voltage is also a switching voltage
• Relay output suitable for inrush current 65 A < 20 ms (NO), continuous current 6 A, total current 10 A
• generous installation space - no additional distribution box required
