Information About AFRB24-S
The AFRB24-S is part of Belimo’s fail-safe actuator range for HVAC air damper applications. Its galvanized steel and plastic housing provides a durable enclosure suited to mechanical building-system installations. The actuator supports selectable motor direction through clockwise or counterclockwise mounting and reversible fail-safe operation. Two SPDT auxiliary switches provide position-related switching functions for connected control or monitoring equipment.
Key Features:
- 24 V AC/DC Supply: Operates from a nominal 24 V AC or DC power source.
- On/Off Control: Provides two-position actuator control for damper applications.
- Fail-Safe Operation: Returns to the required safety position in less than 20 seconds.
- 90° Rotation: Provides the angular travel required for standard damper positioning.
- Motor Running Time: Completes 90° motorized rotation in 75 seconds.
- Auxiliary Switches: Includes two SPDT switches rated for switching and position indication functions.
- Manual Override: Includes a supplied 5 mm hex crank for manual adjustment during servicing.
- NEMA 2 Enclosure: Provides a protected housing for indoor HVAC installation environments.
The AFRB24-S delivers the reliability and precision required for fail-safe HVAC damper control and air-handling applications.
