It incorporates Belimo MFT multi-functional technology, allowing field configuration of control signals, operating ranges, and actuator response characteristics. The actuator is equipped with electronic overload protection throughout the full rotation range and a double-insulated design to support safe and reliable operation. Reversible fail-safe action, adjustable mechanical end stops, and selectable motor direction provide flexibility during installation and commissioning. Key Features Spring Return Fail-Safe Operation: Integrated spring mechanism ensures automatic return to a predefined safety position during power loss for system protection. High Torque Output: Delivers a constant 270 in-lb (30 Nm) torque suitable for large or high-pressure air damper applications. MFT Programmable Control Technology: Supports multiple control modes including 2…10 V, 4…20 mA, PWM, on/off, and floating point for broad system compatibility. Configurable Control Range: Adjustable start and end points allow precise alignment of actuator response with control system requirements. Integrated Position Feedback: Provides a variable 2…10 V feedback signal for continuous position monitoring and closed-loop control. Electronic Overload Protection: Protects internal components throughout the full 0…95° rotation range against mechanical overload or obstruction. Manual Override Capability: Supplied hex crank allows manual damper positioning during commissioning, testing, or maintenance. The EFB24-MFT delivers the reliability and precision required for programmable modulating airflow control and dependable fail-safe damper operation in HVAC systems.
