Information About AFB24-MFT
The AFB24-MFT is part of Belimo’s AFB series of multi-functional spring return actuators developed for flexible and intelligent HVAC damper control. It features electronic overload protection across the full rotation range and a double-insulated design to support reliable long-term operation. The actuator uses Belimo’s MFT technology, allowing field configuration of control signals, operating ranges, and response behavior to match specific system requirements. Reversible fail-safe action, adjustable mechanical end stops, and selectable motor direction provide installation flexibility across a wide range of damper applications.
Key Features
- Multi-Functional Technology MFT: Supports configurable control modes including 2…10 V, 4…20 mA, PWM, on/off, and floating point for maximum system compatibility.
- Spring Return Fail-Safe Operation: Integrated spring mechanism ensures rapid return to a predefined safety position during power loss.
- 20 Nm Constant Torque Output: Provides stable 180 in-lb torque suitable for medium and large dampers under varying airflow conditions.
- Configurable Control Range: Adjustable start and end points allow precise matching of actuator response to control system requirements.
- Integrated Position Feedback: Delivers a variable 2…10 V feedback signal for continuous monitoring and closed-loop control.
- Electronic Overload Protection: Protects internal components throughout the full 0…95° rotation range against mechanical overload.
- Manual Override Capability: Supplied hex crank enables manual positioning during commissioning, testing, or maintenance.
The AFB24-MFT delivers the reliability and precision required for advanced modulating airflow control and dependable fail-safe damper operation in HVAC systems.
