BACring DPM-M2A2
Description
The BACring DPM-M2A2 is primarily used when analog signals are required, for example for percentage-based position control of dampers or for power-dependent control of smoke extraction fans.
It combines the digital open/close logic for two motorized dampers with additional 0–10 V analog inputs and outputs for closed-loop control functions (measuring, controlling, regulating).
Communication is carried out via the BACring bus protocol.
