Description
The Siemens GCA161.1U is a spring-return (SR) rotary actuator engineered for precise modulating control in commercial HVAC systems. Powered by 24 VAC and accepting a 0–10 VDC control signal, this actuator delivers accurate, proportional positioning for dampers and rotary valves in building automation and air-handling applications.
Key Features
- Spring-return (SR) operation ensures fail-safe positioning on power loss
- 24 VAC supply voltage for compatibility with standard BAS and HVAC control panels
- Modulating 0–10 VDC control signal for precise proportional positioning
- Designed for rotary valve and damper actuator applications
- Compact, robust construction suitable for commercial building automation environments
- Siemens Building Technology quality and reliability
Application
The GCA161.1U is ideal for use in air handling units, VAV systems, and hydronic valve control where modulating, fail-safe actuation is required. Its 0–10 VDC input integrates seamlessly with DDC controllers and building management systems (BMS).
