IO Modules


The Metz Connect BMT-AOP4 BACnet MS/TP IO module with 4 analog outputs was developed for decentralised switching tasks.

It is suitable as encoder for control variables, for example for electrical vent and mixing valves, valve positions, etc. The outputs can be output by means of standard objects via a BACnet client.
