BMT-TP BACnet MS/TP Mixed I/O Module

The three-point BACnet MS/TP module with 6 digital inputs, 2 two-level relay outputs, and 2 digital outputs has been developed for decentralized switching tasks.
It is suitable for switching, for example, multi-level pumps and fans or ventilation grilles. In case of heavy inductive loads, it is recommended to protect the relay contacts with an RC element.
Inputs and outputs can be switched and scanned using standard objects via a BACnet client. Input terminals 1 to 6 are wired with C2 terminals on two poles to switches or potential-free contacts. The module features manual control for the outputs.
The module address and baud rate are set via two address switches on the front.
Suitable for decentralized mounting on a TH35 DIN rail
according to IEC 60715 in electrical distribution cabinets
