Information About LMX24-MFT
The LMX24-MFT is part of Belimo’s LM series of compact damper actuators designed for accurate airflow control in commercial HVAC systems. It incorporates Belimo MFT technology, allowing field configuration of control signals, operating modes, and response behavior to match specific system requirements. The actuator features electronic overload protection throughout the full rotation range to protect internal components and ensure consistent torque output. Its lightweight construction, plenum-rated cabling, and selectable direction of motion support flexible installation and long-term reliable operation.
Key Features
- Non Fail-Safe Operation: Provides powered damper positioning without spring return for applications where fail-safe action is not required.
- 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.
- 5 Nm Constant Torque Output: Delivers stable 45 in-lb torque suitable for small to medium damper applications requiring precise modulation.
- Configurable Control Range: Adjustable start and end points allow fine tuning of actuator response to meet control system requirements.
- Integrated Position Feedback: Supplies a variable 2…10 V feedback signal for continuous damper position monitoring and closed-loop control.
- Electronic Overload Protection: Protects the actuator throughout the full 0…95° rotation range against obstruction or excessive load.
- Manual Override Push Button: Enables local damper positioning during commissioning, testing, or maintenance without tools.
The LMX24-MFT delivers the reliability and precision required for programmable modulating airflow control in non fail-safe HVAC damper applications.
