Siemens Building Technology GQD151.1P Actuator

The Siemens GQD151.1P Actuator is a direct-coupled, spring return electronic actuator designed specifically for modulating control of HVAC dampers in constant or variable air volume systems. Engineered with a compact footprint, this 24V damper actuator delivers 20 lb-in (2 Nm) of torque, making it a reliable solution for economizers, residential zone dampers, and small air handling units. It operates via a 2-10 VDC modulating signal and features integrated position feedback, allowing for precise tracking of damper orientation. As a specialized HVAC actuator replacement, the GQD151.1P serves as the recommended upgrade and direct replacement for M9203-GGB-2 components, ensuring seamless integration into existing control loops.

Constructed for demanding environments, the Siemens OpenAir series includes a plenum-rated housing and 3-foot pre-cabled leads to accelerate field installation. The bi-directional fail-safe spring return mechanism ensures dampers move to a "0" position during power loss, protecting system integrity. With a 30-second drive time and signal inversion capabilities, this modulating damper motor provides the technical flexibility required for balancing mixed air, return air, and exhaust air applications.

• Precise Control: Provides linear 2-10 VDC modulation for high-accuracy air flow regulation.
• Fail-Safe Security: Integrated mechanical spring return ensures a reliable default position upon loss of power.
• Broad Compatibility: Acts as an efficient M9203-GGB-2 replacement with a small frame for tight spaces.
• Plenum Rated: UL listed and rugged construction suitable for installation within HVAC ductwork and plenums.
• Feedback Monitoring: Built-in 2-10 VDC output signal allows for real-time remote position verification.

Is the GQD151.1P compatible with 24 VAC and 24 VDC power supplies?
Yes, this unit is designed to operate on a 24 VAC/DC nominal power supply, making it versatile for various HVAC control board configurations.

Can I use this to replace a Johnson Controls M9203-GGB-2?
The GQD151.1P is the direct technical successor and replacement for the M9203-GGB-2 actuator, offering comparable torque and control signals.

Does this actuator support signal inversion?
Yes, the GQD151.1P supports signal inversion (2-10 VDC or 10-2 VDC) to match the specific logic of your controller.
