Damper actuator with spring return for control of dampers during power failures. For 0...10 V control signal.

  • RDAB20S-24A - Damper actuator, 20 NmTorque 20 Nm
  • For dampers up to 4 m2 in size
  • 24 V AC/DC
  • 0...10 V DC continuous control signal

RDAB20S-24A is a spring return actuator for operating air control dampers power failures.

Operation
When the supply voltage is connected, the actuator moves to a working position corresponding to the strength of the control signal (0...10 V DC.) The measuring voltage U permits the damper position (0...100%) to be set electrically and simultaneously serves as a control signal for additional actuators.
