Belimo EFB24-MFT-S Actuator
The Belimo EFB24-MFT-S Actuator is a high-torque spring return actuator designed for the fail-safe operation of large dampers and valves in demanding HVACR applications. Delivering 270 in-lb of torque, this unit utilizes Multi-Function Technology (MFT) to provide versatile control options, including proportional control, floating point, and on/off configurations. It supports 24V AC/DC power inputs and features a built-in auxiliary switch for position signaling or secondary equipment interlocking. With an internal impedance of 500 Ohm for 4-20mA and 1500 Ohm for PWM signals, this actuator ensures precise modulation and peak performance in complex building automation systems. Built for durability, the heavy-duty damper actuator maintains reliable operation under high static pressure, offering mechanical fail-safe positioning during power loss to protect sensitive system components from damage.
- 270 in-lb Torque Output: Provides ample power for large-scale air dampers and high-pressure butterfly valve assemblies.
- Multi-Function Technology (MFT): Allows field configuration of input signals and feedback for maximum job site flexibility.
- Fail-Safe Spring Return: Ensures 100% mechanical closure or opening upon loss of power for system safety.
- Integrated Auxiliary Switches: Dual SPDT switches facilitate easy integration with fan starters or status monitoring panels.
- NEMA 2 Protection: Rugged housing design suitable for standard mechanical room environments and air handling units.
Common Questions
How do I configure the signal input on the EFB24-MFT-S?
The MFT parameters can be adjusted using Belimo PC Tool or the ZTH US handheld tool to set the desired 4-20mA, 2-10VDC, or PWM control signal based on the controller output.
Can this actuator be used in tandem for higher torque requirements?
Yes, the EFB series supports master-slave synchronization when mounted on a common shaft, effectively doubling the torque for extremely large dampers.
What is the typical runtime for the spring return function?
The EFB24-MFT-S typically features a motor run time of less than 150 seconds and a mechanical spring return time of less than 20 seconds at ambient temperature.
