Siemens Building Technology GCA163.1U Actuator
The Siemens Building Technology GCA163.1U Actuator is a heavy-duty OpenAir spring return electronic damper actuator engineered for precise control in high-torque HVAC applications. Delivering 160 lb-in (18 Nm) torque, this unit is built for modulating control of return air, mixed air, and exhaust dampers in both constant and variable air volume (VAV) systems. Operating on 24VAC/DC, the GCA163.1U utilizes brushless DC motor technology to ensure stall protection and long-term reliability without the maintenance overhead of brushed alternatives. A critical feature for technicians is the adjustable start and span (offset 0 to 5 VDC, span 2 to 30 VDC), allowing you to fine-tune the 0-10VDC control signal to match specific field requirements. The self-centering shaft coupling accommodates various shaft sizes, significantly reducing installation time on the job site. Built for durability, the die-cast aluminum housing is NEMA 2 rated, providing robust protection for internal gear trains and electronic components.
- High Torque Output: Provides 160 lb-in (18 Nm) of torque, sufficient for large dampers and high-pressure airflow systems.
- Fail-Safe Operation: Mechanical spring return ensures the damper reaches a secure position during power loss.
- Signal Customization: Integrated adjustable start and span allows for precise 0-10VDC or 2-10VDC field calibration.
- Ease of Installation: Features a patented self-centering shaft adapter and 3-foot pre-cabled 18 AWG leads.
- Quiet Performance: Operates at less than 45 dBA, making it ideal for noise-sensitive commercial environments.
Can the GCA163.1U be mounted outdoors?
Standard installation is rated for NEMA 2/IP54. For outdoor or NEMA 3R applications, the actuator must be installed vertically using an ASK75.1U weather shield.
How do I adjust the fail-safe direction?
The direction of the spring return fail-safe (clockwise or counter-clockwise) is determined by which side of the actuator faces the damper shaft during mounting.
What is the purpose of the 5-degree preload?
The unit is factory-shipped with a 5-degree preload to ensure tight damper closure and seal compression even as gaskets age.
