Information About LMB24-MFT
The LMB24-MFT is part of Belimo’s LMB Series of electric rotary actuators for HVAC dampers. Its brushless DC motor incorporates electronic overload protection and digital rotation sensing to protect the drive during stalled conditions. The universal clamp mounts directly onto compatible round shafts from 1/4 inch to 5/8 inch in diameter, with an accessory clamp available for shafts up to 3/4 inch. Factory settings provide 2–10 VDC operation, while compatible configuration tools allow control parameters to be adjusted for the installation.
Key Features:
- Programmable Control: Supports configurable voltage, PWM, floating-point, and on/off operation through Multi-Function Technology.
- Torque Output: Delivers 45 in-lb for dampers sized according to the damper manufacturer’s requirements.
- Dual Supply Compatibility: Operates from either 24 VAC or 24 VDC power.
- Analog Input: Accepts a factory-default 2–10 VDC positioning signal.
- Current Signal Conversion: Supports 4–20 mA control using an external ZG-R01 500-ohm resistor.
- Position Feedback: Provides a 2–10 VDC output for monitoring actuator position.
- Adjustable Running Time: Allows motor travel time to be configured between 35 and 150 seconds.
- Reversible Rotation: Includes a 0/1 switch for selecting motor direction.
- Manual Override: Uses an external push button to disengage the gears for manual positioning.
- Adjustable Travel: Provides up to 95° rotation with a mechanical travel stop.
- Electronic Protection: Protects the drive against overload throughout its operating rotation.
- Reduced Holding Consumption: Uses 1.2 W while maintaining position.
The LMB24-MFT delivers the reliability and precision required for programmable damper positioning and airflow regulation in commercial HVAC systems.
