EASYF-VDC CONNECTIONS
General:
The EasyF-VDC module is used for connecting and controlling
two independent steadily regulating
DC drives, for example VAV (Variable Air Volume) or valves.
The two independent analogue 0-10 V inputs can receive the
signal, for example of a CO
2
sensor, a temperature sensor,
etc., and be used, for example, for monitoring the air quality
or the like.
Cons. No.
