Belimo TFLB24 Actuator
The Belimo TFLB24 is a spring return damper actuator designed for reliable fail-safe operation in HVAC systems. Operating on 24V AC/DC, this actuator provides 22 in-lb torque, making it an ideal choice for smaller dampers and air handling units requiring dependable shut-off during power loss. The brushless DC motor utilizes microprocessor control to ensure precise timing and consistent performance without the maintenance associated with traditional brushed motors. Its compact design allows for easy installation in tight mechanical spaces, while the mechanical position indicator provides clear visual feedback for field technicians during system balancing.
Engineered for high-cycle applications, the TFLB24 features a rugged housing that withstands demanding environments. The on/off control logic simplifies wiring for standard automation sequences, and the integrated universal spindle clamp accepts a variety of shaft sizes, reducing the need for additional adapters on the job site. For service pros, the manual override functionality allows for manual positioning during commissioning or emergency troubleshooting, ensuring the system remains operational under all conditions.
- Spring Return Fail-Safe: Ensures dampers move to a safety position during power interruptions.
- High Torque Output: Delivers a consistent 22 inch-pounds of torque for low-leakage performance.
- Direct Mounting: Mounts directly to damper shafts with a robust universal clamp.
- Electronic Stall Protection: Protects the motor from burnout when the damper reaches its end-of-travel.
- Wide Temperature Range: Rated for operation in ambient temperatures from -22°F to +122°F.
Common Questions
How do I reverse the fail-safe direction on the TFLB24?
The fail-safe direction (normally open or normally closed) is determined by the orientation of the actuator on the damper shaft. Flipping the unit over reverses the spring return action.
Can this actuator be used with modulated signals?
No, the TFLB24 is designed specifically for on/off control applications. For proportional control, a model from the TFX series would be required.
What is the typical run time for this actuator?
The motor drive time is approximately 75 seconds, while the spring return provides a fail-safe closure in under 25 seconds.
