BMT-DIO4/2 BACnet MS/TP

The BACnet MS/TP module with 4 digital inputs and 2 relay outputs with manual control has been developed for managing 2 relay outputs with manual control for decentralized switching tasks.
It is suitable for accommodating, for example, light switches and window contacts in a room, switching two light strips, or for controlling louvers. It can also be used to control 2 motorized fire dampers.
In case of heavy inductive loads, it is recommended to protect the relay contacts with an RC element. The inputs can be used as contact or voltage inputs. The inputs and outputs can be switched and scanned via
standard objects via a BACnet client. The module's address and baud rate are set using two address switches on the front.
Suitable for decentralized mounting on DIN rail TH35 according to IEC 60715 in electrical distribution cabinets
