BMT-DIO4/2 IP65 BACnet MS/TP

The BACnet MS/TP module with IP65 housing, featuring 4 digital inputs and 2 relay outputs with manual control, was developed 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 damper control. 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 by a BACnet client. The module address and baud rate are set using two address switches.
