Belimo ARX24-MFT95 Actuator Motor

The Belimo ARX24-MFT95 is a robust non-spring return actuator engineered for precise control in high-torque HVAC applications. Delivering 180 in-lb of torque, this motor is designed to automate dampers and valves with steady, reliable positioning. It operates on a universal 24VAC/DC power supply and features Multi-Function Technology (MFT), allowing for wide-ranging field adjustability of control signals and feedback. This specific MFT actuator is pre-configured for 4-20mA control via a 500 Ohm resistor, while also supporting PWM (Pulse Width Modulation) at 1500 Ohm, floating point, and standard On/Off signals. The brushless DC motor utilize microprocessor control to maintain constant torque and provide electronic stall protection across its full 95-degree rotation. Built for professional commercial HVAC automation, the ARX24-MFT95 ensures seamless integration into existing BAS (Building Automation Systems), providing the durability required for heavy-duty air handling units and large-scale zoning applications.

Key Benefits

• High Torque Output: Provides 180 in-lb (20 Nm) for reliable operation of large damper blades and valves.
• MFT Versatility: Field-customizable control input and feedback signals allow for precise proportional control tuning.
• Digital Accuracy: Microprocessor-based sensing eliminates the need for limit switches by detecting end-of-rotation stops.
• Universal Compatibility: Works with 24V actuator circuits and offers multiple signal options including floating point and PWM.
• Extended Service Life: Brushless DC motor technology reduces wear and ensures consistent runtime regardless of load.

Common Questions

Can I field-configure the rotation speed or feedback signal?
Yes, as part of the MFT series, parameters such as running time, control signal, and 2-10VDC feedback can be adjusted using Belimo PC Tool software or a handheld ZTH US tool.

What happens if the actuator encounters an obstruction?
The Belimo ARX24-MFT95 features electronic stall protection; it will stop automatically if it detects an overload, preventing motor burnout without requiring manual reset.

Is this model suitable for fail-safe applications?
No, this is a non-spring return actuator. It will maintain its last position upon loss of power rather than returning to a baseline safety position.
