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