Siemens GQD126.1P Spring Return Damper Actuator 20 lb-in 24V AC/DC

The Siemens GQD126.1P is a spring return damper actuator designed for HVAC control applications requiring reliable, fail-safe operation. This compact actuator delivers 20 lb-in of torque and operates on 24V AC or DC power, making it compatible with most building automation systems.

Key Features:

• Spring return operation for fail-safe positioning when power is lost
• 20 lb-in (2.3 Nm) torque output for controlling small to medium dampers
• Universal 24V AC/DC power supply for flexible installation
• Two auxiliary switches for position indication and control feedback
• 2-position control for simple open/close applications
• Durable construction for long service life in commercial HVAC systems
• Direct-mount design for easy installation on damper shafts

This actuator is ideal for controlling zone dampers, fresh air intake dampers, and exhaust dampers in commercial building HVAC systems. The spring return mechanism ensures the damper returns to a safe position during power failures, while the auxiliary switches provide valuable feedback for building management systems.
