Analog Output Module
BMT-AO4
1108851302
1. Description
The BACnet MS/TP module with 4 analog outputs was develo-
ped for decentralized 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. The module is addressed and the baud rate is set by
means of two address switches on the front.
Suitable for decentralized mounting in serial sub-distributor.
