AFB24-MFT | Belimo | Damper ActuatorAFB24 MFT Damper Actuator, multifunctional control, 24V, spring return (fail safe) For fail safe, modulating control of dampers in HVAC systems. Actuator sizing should be done in accordance with the damper manufacturers specifications. A feedback signal is provided for position indication for master slave applications. Two AFs can be piggybacked for torque loads to max. 360 in lb. Minimum 3 4 diameter shaft. OR Maximum of three AFs can be piggybacked

A actuators provide true spring-return operation for reliable fail-safe application and positive close-off on UL555S dampers

10 V feedback signal is provided for position indication

It features specialized functions for seamless integration with a wide range of building automation systems

A crank arm and several mounting brackets are available for applications where the actuator cannot be direct coupled to the damper shaft
