Description
Siemens GCA121.1P Spring Return 24VAC ON/OFF Rotary Actuator
The Siemens GCA121.1P is a spring-return rotary actuator engineered for dependable ON/OFF damper control in commercial and light industrial HVAC applications. Powered by a 24VAC supply, this actuator provides fail-safe spring-return operation, automatically returning to its de-energized position upon power loss to protect building systems and maintain occupant safety.
Key Features
- Spring-return (SR) fail-safe operation for reliable shutoff on power loss
- 24VAC operating voltage for compatibility with standard HVAC control systems
- ON/OFF control signal for straightforward two-position damper actuation
- Compact rotary design suitable for a wide range of damper and valve applications
- Built to Siemens Building Technology quality standards for long service life
- Ideal for commercial HVAC air handling, ventilation, and building automation systems
Application
The GCA121.1P is designed for use in building automation and HVAC control systems where two-position (open/close) damper actuation is required. The spring-return mechanism ensures fail-safe positioning, making it well suited for fresh air, exhaust, and mixed-air damper control in air handling units and rooftop equipment.
