Product specification
The BACnet MS/TP module with 4 analog outputs was developed 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. Each output can be set for automatic or manual operation by means of 4 potentiometers at the front. 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.
• Connection with screw type terminal blocks
