Metz Connect BMT-TO4
The Metz Connect BMT-TO4 BACnet MS/TP IO module with 4 digital triac outputs was developed for decentralized switching tasks.
It is suitable for switching electrical components, such as relays, contactors, HLK valves, etc. The outputs can be switched by means of standard objects via a BACnet client. In addition, the outputs can be overridden manually by means of switches on the device.
Protocols: BACnet MSTP
Product Description
The module is addressed and the baud rate is set by means of two address switches on the front. Suitable for decentralized mounting on DIN TH35 rail according to IEC 60715 in electrical distribution cabinets.
