Belimo GMX24-MFT Actuator

The Belimo GMX24-MFT Actuator is a high-torque non-spring return actuator designed for the precise control of large dampers and valves in demanding HVACR systems. Delivering 360 in-lb of torque, this Multi-Function Technology (MFT) actuator offers unmatched versatility for contractors, allowing for field-programmable control signals including 2-10VDC, 4-20mA (via 500 Ohm resistor), PWM (via 1500 Ohm resistor), floating point, and on/off configurations. Operating on a 24VAC/DC power supply, it features a brushless DC motor with overload protection, ensuring consistent performance and a long service life without the need for limit switches. Its NEMA 2 (IP54) housing makes it suitable for various indoor environments, providing reliable automation for air handling units and complex terminal equipment. The MFT technology enables custom run times and signal adaptations, making it a critical component for optimizing building automation system (BAS) integration and HVAC energy efficiency.

• 360 in-lb Torque Output: Provides reliable actuation for large-scale dampers and high-pressure valve assemblies.
• Multi-Function Technology (MFT): Allows technical staff to customize control signals and feedback for specific application requirements.
• Brushless DC Motor: Digitally controlled for precise positioning and enhanced durability under constant load.
• Universal Compatibility: Seamlessly integrates with 2-10VDC, 4-20mA, and Pulse Width Modulation signals.
• Manual Override: Features an external push button to allow for manual positioning during commissioning or system testing.

Can the GMX24-MFT be used for 4-20mA control signals?
Yes, by utilizing a 500 Ohm resistor, the Belimo GMX24-MFT can be field-configured to accept 4-20mA inputs for proportional control.

Is this a spring return actuator?
No, this model is a non-spring return actuator. It maintains its last position upon loss of power unless a fail-safe accessory is integrated.

How do I adjust the running time of the actuator?
The run time is programmable via the Belimo MFT software or handheld tools, allowing technicians to synchronize the actuator with specific system cycles.
