Belimo EFB24-MFT Actuator
The Belimo EFB24-MFT Actuator is a high-torque, spring return damper actuator designed for fail-safe application in demanding HVAC systems. Engineering for reliability, this 24V damper motor provides 270 in-lb of torque, making it suitable for large-scale air handling units and complex control sequences. Utilizing Multi-Function Technology (MFT), this unit offers unmatched versatility for contractors, supporting 4-20mA (via 500 Ohm resistor), PWM (1500 Ohm), floating point, and On/Off control signals. The brushless DC motor is controlled by a specialized microprocessor that adjusts the runtime independently of the load while providing digital rotation sensing to prevent stall damage. This HVAC actuator ensures consistent performance across 95 degrees of rotation with integrated electronic overload protection. Whether you are performing a Belimo EFB24-MFT replacement or a new field installation, the universal shaft clamp facilitates a direct-coupled connection to shafts ranging from 1/2 to 1.05 inches, ensuring a secure fit on standard and jackshaft configurations.
Key Benefits- High Torque Output: Delivering 270 in-lb [30 Nm] for reliable operation of larger dampers and valves.
- MFT Flexibility: Programmable control signals including 2-10 VDC, 4-20mA, and pulse width modulation for precise building automation integration.
- Fail-Safe Security: True mechanical spring return ensures the damper returns to the safety position during a power loss.
- Efficient Power Usage: Maintenance-free operation with a low 9.5W power consumption during running and 4.5W in the holding position.
- Rugged Housing: NEMA 2 / IP54 rated aluminum die-cast and plastic casing designed for professional mechanical environments.
How do I wire the Belimo EFB24-MFT for 4-20mA control?
To utilize a 4-20mA signal, you must install a 500 Ohm resistor in parallel with the input signal wire (typically wire 3) to convert the current to the required voltage range.
Can two EFB24-MFT actuators be mounted on the same shaft?
Yes, for high-torque requirements up to 540 in-lbs, two EFB actuators can be "piggybacked" on a single shaft provided they are wired in parallel and the shaft diameter is at least 3/4 inch.
What does the MFT designation mean for my installation?
Multi-Function Technology allows the actuator to be customized or reprogrammed for different control signals, running times, and feedback parameters using Belimoās PC Tool or ZTH handheld service tool.
