BMT-DIO4/2 IP 230 BACnet MS/TP

The BACnet MS/TP module in an IP65 enclosure with 4 digital inputs and 2 relay outputs with manual operation level was developed for decentralized switching tasks. It is suitable, for example, for light switches and window contacts in a room and for switching two light strips or for controlling a blind or venetian blinds. It can also control 2 motorized fire dampers.
In this case, the relay contacts must be protected with appropriate measures depending on the load. The inputs must be wired with potential-free contacts. Via a BACnet client, the inputs and outputs can be switched and queried using standard objects. The module address and transmission speed are set via two rotary switches.
