Description
The Belimo TR24-SR-T is a non-spring return, proportional (modulating) damper actuator designed for precise, reliable control in commercial and industrial HVAC applications. Powered by 24Vac or 24Vdc, this actuator accepts a proportional control signal to deliver accurate, variable positioning of damper blades — making it an ideal choice for air handling units, VAV systems, and building automation applications that demand modulating control.
The terminal strip wiring connection simplifies field installation and integration, reducing wiring time and the risk of connection errors. As a non-spring return design, the actuator holds its last commanded position upon power loss, making it well-suited for applications where fail-in-place operation is preferred.
Belimo is a globally recognized leader in actuator and valve technology, known for robust construction, long service life, and consistent performance across demanding HVAC environments.
