Belimo LMB24-MFT Actuator
The Belimo LMB24-MFT Actuator is a non-spring return motor designed for precise damper control in commercial HVAC systems. Delivering a steady 45 in-lb torque, this direct-coupled actuator supports a wide variety of control signals through Multi-Function Technology (MFT). It is factory-set for 2-10VDC modulation but is field-programmable to handle floating point, on/off, and PWM control. For 4-20mA logic, a 500 Ohm resistor (model ZG-R01) is required to convert the signal. Operating on 24VAC/DC, the unit features a brushless DC motor with electronic overload protection throughout its 0 to 95-degree rotation, eliminating the need for mechanical limit switches. The NEMA 2 rated housing includes a manual override button and a universal clamp compatible with 1/4 inch to 5/8 inch round shafts, ensuring seamless BAS integration for modulating dampers up to 11 square feet.
Key Benefits for Contractors- Universal Compatibility: The MFT programmable logic allows one damper actuator to replace multiple fixed-signal models, reducing truck stock.
- Reliable Performance: Brushless DC motor technology prevents stalling and ensures constant torque delivery regardless of load.
- Faster Installation: The direct-coupled design requires no crank arms or linkages, mounting directly to the drive shaft.
- High Efficiency: Extremely low power consumption (1.2W in holding mode) reduces transformer sizing requirements for building automation.
- Flexible Field Setup: Includes a reversing switch and manual disengagement button for easy damper setup and testing.
How do I wire the Belimo LMB24-MFT for a 4-20mA signal?
To accept a 4-20mA input, you must install a 500 Ohm resistor across the input signal (Wire 3) and common (Wire 1). This converts the current to a 2-10VDC signal that the MFT actuator recognizes.
Can I use this actuator for fire and smoke dampers?
No, the LMB24-MFT is a non-spring return actuator. It will remain in its last position upon loss of power. For safety applications requiring a fail-safe position, a spring-return model must be used.
What is the maximum damper size this motor can handle?
With 45 in-lb torque, it is generally rated to drive dampers up to 11 sq. ft., though you should always verify the manufacturer's torque requirements for your specific HVAC damper.
