Siemens GMA151.1P Spring Return Damper Actuator 2-10V 62 lb-in Plenum Rated

The Siemens GMA151.1P is a spring return damper actuator designed for HVAC control applications requiring plenum-rated components. This actuator provides 62 lb-in of torque and operates on 24V AC/DC power with 2-10V DC modulating control signal input.

Key Features:

• Spring return operation for fail-safe positioning when power is lost
• 62 lb-in (7 Nm) nominal torque output for medium to large damper applications
• 2-10V DC modulating control signal for precise damper positioning
• 24V AC/DC universal power supply compatibility
• Plenum-rated construction approved for installation in air handling spaces
• Direct-coupled mounting for NEMA dampers and valve applications
• Position indication for visual verification of actuator status
• 90-degree rotation for standard damper control

This actuator is ideal for commercial HVAC systems, building automation applications, and air handling units where reliable, modulating damper control is required. The spring return mechanism ensures the damper returns to a safe position during power failure, making it suitable for life safety and smoke control applications.
