Information About NMX24-MFT
The NMX24-MFT is part of Belimo’s NM series of compact damper actuators designed for reliable and flexible airflow control in commercial HVAC systems. It incorporates Belimo MFT multi-functional technology, allowing field configuration of control signals, operating ranges, and actuator response to meet specific application requirements. The actuator features electronic overload protection throughout the full 0–95° rotation range to protect internal components and ensure consistent torque output. Its lightweight construction, plenum-rated cabling, and selectable direction of motion simplify installation and support long-term dependable operation.
Key Features
- Non Spring Return Operation: Provides powered damper positioning without fail-safe spring action for applications where return on power loss 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.
- 10 Nm Constant Torque Output: Delivers stable 90 in-lb torque suitable for small to medium air dampers requiring accurate modulation.
- Configurable Control Range: Adjustable start and end points allow precise alignment of actuator response with building automation 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 NMX24-MFT delivers the reliability and precision required for programmable modulating airflow control in non fail-safe HVAC damper applications.
