Parallel controlled pressure regulation with external regulator

Pressure measurement and regulating damper with external regulator that variably regulate the duct pressure in parallel between minimum and maximum pressure depending on the control signal.

Demand control via analogue control signal (Y). Return of the current pressure via analogue actual value signal (U).

Possibility of Modbus control/communication or Modbus in combination with analogue signals.
