Belimo TF24-SR Damper Actuator

Spring-return ventilation damper actuator with modulating position control.

Model / SKU: TF24-SR
Category: Heating & Ventilation
Product type: Damper actuator
Role: Actuator / load

Control & power

Control type: 0–10 / 2–10 V control · Open / close control
Power supply: 24 V AC/DC

Use the standard 2–10 V modulating control input with a separate 24 V supply. Spring return moves the damper to its configured fail-safe direction when supply is lost.

A suitable smart controller can expose supported functions to Matter. The control type alone does not confirm electrical compatibility or actual position feedback.
