Belimo EFB24-S Actuator
The Belimo EFB24-S Actuator is a heavy-duty spring return actuator designed for high-torque applications requiring reliable fail-safe operation. Engineered for On/Off control, this unit delivers 270 in-lb of torque, making it suitable for large dampers and control valves in demanding HVAC automation systems. It operates on a universal 24VAC/DC power supply and features an integrated SPDT auxiliary switch for position feedback or triggering peripheral equipment. The mechanical spring return mechanism ensures a positive seal or fully open state during power loss, providing critical protection for air handling units and sequence of operations. Built with a rugged NEMA 2 housing, it withstands harsh mechanical room environments while maintaining precision timing. Contractors choose this model for its simplified installation, direct-coupled mounting, and high-cycle life in commercial air damper control.
Key Benefits:- High Torque Output: Provides 270 in-lb (30 Nm) to drive large dampers without binding.
- Fail-Safe Reliability: Mechanical spring return ensures the system reverts to a safe state during power failure.
- Auxiliary Feedback: Integrated adjustable auxiliary switch allows for remote monitoring of actuator position.
- Universal Power: Compatible with both 24VAC and 24VDC circuits for versatile field application.
- Robust Construction: Designed for long-term performance in high-demand building automation systems.
What is the typical run time for the EFB24-S?
The motor drive time is approximately 75 seconds, while the spring return fail-safe closes the damper in less than 20 seconds, ensuring rapid response in emergency scenarios.
Can this actuator be mounted in any orientation?
Yes, it offers multi-position mounting with a universal clamp, though it is standard practice to avoid mounting with the shaft pointing down in high-moisture environments.
How do I wire the auxiliary switch for status verification?
The internal SPDT switch can be field-adjusted to trigger at specific angles, allowing you to confirm if a damper is fully closed or open via your controller’s binary input.
