Belimo SF24A-MOD Damper Actuator 180 in-lb Spring Return 24V Modbus RTU

The Belimo SF24A-MOD is a spring return damper actuator designed for reliable HVAC control applications. This actuator provides 180 in-lb of torque with 24VAC/DC power and features Modbus RTU communication protocol for seamless integration into building automation systems.

Key Features:

• 180 in-lb (20 Nm) nominal torque for medium-sized damper control
• Spring return mechanism for fail-safe operation - returns to home position on power loss
• 24VAC/DC universal voltage operation
• Modbus RTU serial communication for BAS integration
• Compact, weather-resistant housing suitable for field or duct mounting
• Rotary electronic actuator with 95° nominal rotation angle
• Position indication via auxiliary switch or feedback signal
• Quick mounting with universal bracket system

Ideal for applications requiring damper control in air handling units, VAV boxes, and commercial HVAC systems where digital communication and spring return safety are required. The Modbus RTU interface enables precise positioning control and real-time status monitoring through compatible building automation systems.
