Belimo GMX24-MFT-X1 Actuator

The Belimo GMX24-MFT-X1 is a high-torque rotary actuator engineered for commercial HVAC applications requiring precise damper automation and valve control. Operating on a 24VAC/DC power supply, this Multi-Function Technology (MFT) motor delivers a robust 360 in-lb output, making it ideal for large-scale air handlers and heavy-duty dampers. The non-spring return design supports a versatile range of control signals, including 2-10VDC, 4-20mA (via 500 Ohm resistor), and PWM control (via 1500 Ohm resistor), alongside standard floating point and On/Off configurations. This flexible control actuator allows for field-adjustable parameters such as running time and torque limits, ensuring compatibility with diverse Building Automation Systems (BAS). Built for longevity in rigorous environments, the GMX24-MFT-X1 features manual override capabilities and a standardized U-bolt clamp that fits shafts up to 1.05 inches, streamlining the installation process for mechanical contractors and service technicians in the field.

Key Technical Benefits

• Field Programmable: Utilizes MFT technology to adjust control signals and feedback, reducing the need for multiple SKUs.
• High Torque Output: Provides 360 in-lb torque to reliably drive large dampers or high-pressure valves.
• Universal Compatibility: Works with 24V control logic and integrates seamlessly into varied BAS architectures.
• Direct Mount Design: Simplifies replacement and retrofitting with a versatile shaft clamp and anti-rotation strap.
• Efficient Power Consumption: Optimized for low holding power to minimize energy draw across large networks.

Common Installation Questions

How do I configure the 4-20mA signal?
The GMX24-MFT-X1 requires an external 500 Ohm resistor to convert a 4-20mA signal into the standard 2-10VDC control range used by the onboard processor.

Can this actuator be used in failsafe applications?
No, this unit is a non-spring return actuator. For applications requiring a safety return position upon power loss, a spring-return model must be specified.

What size damper can this motor handle?
With 360 in-lb of torque, this motor typically handles dampers up to 90 square feet, though actual sizing depends on damper construction and air velocity.
