Belimo TR24-SR-T Actuator

The Belimo TR24-SR-T is a high-performance non-spring return actuator designed specifically for the proportional control of small zone valves and terminal units. Operating on a 24VAC/DC power supply, this compact damper actuator utilizes a 2 to 10 VDC control signal to provide a linear torque output of 18 in-lb (2 Nm). The integration of a terminal strip connection simplifies field wiring, making it a preferred choice for contractors managing complex HVAC control systems. Engineered for proportional control, the TR24-SR-T delivers precise positioning with a 90-second run time, ensuring optimal thermal comfort and energy efficiency. Its brushless DC motor technology eliminates the need for limit switches, providing internal electronic protection against overloading throughout its 0 to 95° rotation. This unit is built to interface seamlessly with automated building systems, ensuring reliable performance in demanding commercial environments.

• Precision Modulation: Delivers accurate 2-10 VDC modulating control for fine-tuned flow regulation.
• Simplified Installation: Features a terminal strip for rapid, secure electrical termination in tight spaces.
• Maintenance-Free Design: Brushless DC motor prevents stall-related failures and extends the operational lifecycle.
• Compact Footprint: Low-profile housing allows for installation in constrained plenums and terminal boxes.
• Universal Compatibility: Works efficiently with standard 24V HVAC actuators and controller logic.

How does the TR24-SR-T handle manual overrides?
The unit features a manual override button on the housing, allowing technicians to manually position the valve or damper during commissioning or power loss.

What is the power consumption for this proportional actuator?
The Belimo TR24-SR-T is highly efficient, typically consuming only 0.5W during operation and 0.2W in the held position, minimizing the transformer load.

Can this actuator be mounted in any orientation?
Yes, the NEMA 1 rated housing supports various mounting positions, though vertical orientation is recommended to prevent moisture ingress into the wiring terminals.
