BMT-DO4 BACnet MS/TP 4 digital outputs

The BACnet MS/TP module with 4 digital outputs has been developed for decentralized switching tasks. It is suitable for switching electrical components, such as motors, contactors, lamps, blinds, etc. In the presence of strong inductive loads, it is recommended to protect the relay contacts with an RC element. The module is equipped with a manual control for manual switching of the relays. The outputs can be switched using standard objects via a BACnet client. The module is addressed and the baud rate is set using two address switches on the front. Suitable for decentralized mounting on a TH35 DIN rail according to IEC 60715 in electrical distribution cabinets.
