Description
Siemens GCA164.1P Spring Return Modulating Damper Actuator
The Siemens GCA164.1P is a spring return damper actuator engineered for reliable, precise modulating control in commercial HVAC and building automation applications. Powered by 24 VAC and accepting a 0–10 VDC modulating control signal, this actuator delivers proportional damper positioning to support energy-efficient air distribution and ventilation management. The integrated auxiliary switch provides feedback or interlock capability, making it a versatile choice for a wide range of building automation system (BAS) configurations.
Key Features
- Spring return (SR) fail-safe operation — returns damper to a defined safe position on power loss
- 24 VAC power supply for compatibility with standard HVAC control systems
- Modulating 0–10 VDC control signal for precise proportional damper positioning
- Integrated auxiliary switch (AUX SW) for end-position feedback or interlock wiring
- Designed for commercial HVAC damper and air handling unit applications
- Siemens Building Technology quality construction for long service life
Application
The GCA164.1P is ideal for use in air handling units (AHUs), variable air volume (VAV) systems, economizers, and other commercial HVAC applications where modulating damper control and fail-safe spring return are required. Its 0–10 VDC input integrates seamlessly with most building automation controllers and direct digital control (DDC) systems.
