Belimo AFX24-SR-N4 Actuator

Belimo AFX24-SR-N4 Actuator

The Belimo AFX24-SR-N4 is a heavy-duty spring return actuator designed for fail-safe applications requiring 180 in-lb torque. Operating on a 24V AC/DC power supply, this unit utilizes a 2-10 VDC proportional control signal for precise modulation of dampers or valves in demanding environments. Featuring a rugged NEMA 4 housing (IP66), it provides superior protection against moisture, dust, and outdoor exposure, making it ideal for rooftop units and harsh mechanical rooms. The brushless DC motor is controlled by an Application Specific Integrated Circuit (ASIC) to ensure constant torque and prevent motor burnout at end-of-stroke. This HVAC actuator maintains a consistent 95-degree rotation and provides reliable fail-safe positioning upon loss of power. For contractors, the universal clamp allows for easy installation on damper shafts ranging from 1/2 inch to 1.05 inches, ensuring compatibility with most standard mechanical interfaces in industrial HVAC control systems.

  • NEMA 4/IP66 Rated Enclosure: Engineered for outdoor or wash-down environments where environmental protection is mandatory.
  • 180 in-lb Torque Output: High-torque capacity suitable for large air dampers and high-pressure valve assemblies.
  • Proportional 2-10 VDC Control: Delivers precise modulating control for accurate airflow or fluid regulation.
  • Mechanical Spring Return: Ensures a reliable fail-safe position (Normally Open or Normally Closed) during power interruptions.
  • Electronic Stall Protection: Internal circuitry protects the motor from overloading without the need for limit switches.

Common Questions about the Belimo AFX24-SR-N4

What is the difference between the AFX24-SR and the AFX24-SR-N4?
The "N4" designation indicates a NEMA 4/4X rated housing, which is specifically designed for outdoor use or areas requiring a water-tight seal, whereas the standard AFX model is typically NEMA 2 rated.

Can this actuator be used for both clockwise and counter-clockwise fail-safe?
Yes, the direction of the spring return is determined by the orientation of the actuator during mounting (Side A or Side B), allowing for flexible fail-safe configuration.

What size damper shaft will this actuator accommodate?
The standard universal clamp on the AFX series fits round shafts from 1/2" to 1.05" and square shafts from 13/32" to 3/4".
