Belimo TF24 CA Actuator

The Belimo TF24 CA Actuator is a compact, fail-safe rotary damper actuator delivering 2.5 Nm of torque for reliable open/close control in HVAC systems. It accepts 24 V power from either AC or DC sources (50/60 Hz) and draws about 2 W of running power with a 5 VA input rating, making it suitable for standard building control circuits. In the event of a power loss, the integrated fail‑safe mechanism returns the damper to its designated position, and it completes a full stroke in roughly 75 seconds. The unit is rated IP42 for indoor use and operates with a motor sound power level up to 50 dB(A) under typical running conditions, providing quiet performance in occupied spaces. Designed for dampers in commercial environments, the TF24 CA is well suited for air handling units, VAV terminal units, and other ventilation applications where dependable fail-safe actuation, compact footprint, and straightforward integration with common 24 V controls are essential.
