Metz Connect BMT-DI10
The Metz Connect BMT-DI10 is a BACnet MS/TP IO module with 10 digital inputs was developed for decentralised switching tasks.
It is suitable for detecting potential-free switch states, for example electrical limit switches on vent valves or auxiliary contacts of power contactors. The inputs can be used as contact or voltage inputs.
Protocols: BACnet MSTP
Product Description
The BACnet MS/TP module with 10 digital inputs was developed for decentralised switching tasks. It is suitable for detecting potential-free switch states, for example electrical limit switches on vent valves or auxiliary contacts of power contactors. The inputs can be used as contact or voltage inputs. The inputs can be scanned by means of standard objects via a BACnet client. The module is addressed and the baud rate is set by means of two address switches on the front Suitable for decentralised mounting in serial sub-distributor.
