Belimo AFRX24-MFT-S Actuator
The Belimo AFRX24-MFT-S is a high-torque spring return actuator engineered for precise modulation in demanding HVACR applications. Operating on 24VAC/DC, this 180 in-lb motor is powered by Multi-Function Technology (MFT), allowing for field-programmable control over a wide range of inputs including 4-20mA (via 500 Ohm resistor), PWM (1500 Ohm), floating point, and on/off signals. Standardized with two integral SPDT auxiliary switches, it provides reliable end-position indication and interlock control for fan startups or safety circuits. The brushless DC motor ensures constant running time, independent of load, while the fail-safe spring return mechanism drives the damper or valve to a secure position in under 20 seconds during power loss. This NEMA 4X or NEMA 2 rated unit (depending on specific enclosure selection) is designed for direct-coupled mounting on shafts up to 1.05 inches, providing a robust solution for large air handling units and RetroFIT+ projects requiring 2-10VDC position feedback.
Key Benefits for HVACR Contractors:- Universal Compatibility: Programmable MFT logic supports diverse controller signals, reducing the need to stock multiple specialized actuators.
- Enhanced Torque Performance: Delivers 180 in-lb (20 Nm) of torque, capable of driving large dampers or flanged ball valves like the B6 series.
- Precision Control: Features Digital Rotation Sensing (DRS) and a microprocessor-controlled brushless motor for exact positioning and overload protection throughout the 95° stroke.
- Integrated Signaling: Dual auxiliary switches (one fixed at 10°, one adjustable) allow for seamless integration with building automation systems.
- Field Flexibility: Includes a manual override hex crank and selectable direction of rotation for rapid installation and troubleshooting.
Can the AFRX24-MFT-S be used for 4-20mA control without extra hardware?
It requires a 500 Ohm resistor (such as the ZG-R01) to convert the 4-20mA current signal into the 2-10VDC operating range compatible with the actuator’s input impedance.
Is this actuator suitable for outdoor or washdown environments?
The "X" in the part number often denotes an upgraded enclosure; check specific model markings to confirm NEMA 4X / IP66 rating for high-moisture or corrosive environments versus standard NEMA 2/IP54 units.
How do I adjust the fail-safe direction?
The fail-safe direction is determined by the physical mounting orientation (CW/CCW) of the actuator on the damper or valve shaft; it is not a software-selectable setting.
