Information About BF24-SR
The BF24-SR is a spring-return damper actuator from Belimo’s safety-focused actuator range, engineered for applications requiring controlled positioning and automatic movement to a defined safety position during power loss. It combines a robust motor drive with a mechanical spring-return mechanism, ensuring dependable operation under both normal and emergency conditions. The BF24-SR supports modulating control via a 2…10 V input signal and provides a 2…10 V position feedback output for system integration and diagnostics. Dual auxiliary switches, halogen-free cabling, and selectable mounting orientation allow flexible installation in commercial and industrial HVAC damper assemblies.
Key Features
- Spring-Return Fail-Safe Function: Automatically drives the damper to the safety position in the event of power loss using a high-reliability spring mechanism.
- Modulating Control Signal: Accepts a 2…10 V control input for precise proportional damper positioning.
- High Torque Performance: Provides 18 Nm motor torque and 12 Nm fail-safe torque to handle demanding damper loads.
- Integrated Position Feedback: Supplies a 2…10 V feedback signal to indicate actual damper position with ±5% accuracy.
- Dual Auxiliary Switches: Includes 2x SPDT switches for position indication, interlocking, or system monitoring functions.
- Manual Override Capability: Features a manual override with position stop for commissioning and maintenance procedures.
- Wide Environmental Tolerance: Designed for stable operation across broad temperature and humidity ranges in HVAC environments.
The BF24-SR delivers the reliability and precision required for modulating damper control with fail-safe protection in HVAC systems.
