Siemens Building Technology GCA164.1U Actuator
The Siemens GCA164.1U Actuator is a heavy-duty modulating spring return damper actuator designed for HVAC systems requiring high-torque performance and reliable fail-safe operation. Built with a rugged all-metal housing, this OpenAir GCA Series drive delivers 160 lb-in torque (18 Nm) to manage large dampers in VAV systems, mixed air units, and exhaust applications. It operates on 24VAC/DC power and accepts a 0-10 VDC control signal, providing precise proportional control with built-in position feedback. For complex sequencing, the GCA164.1U features dual auxiliary switches and adjustable start and span (offset/span) to customize the response range. Its brushless DC motor technology ensures stall protection and quiet operation, while the patented self-centering shaft coupling accommodates shafts up to 1 inch, simplifying field installation for service contractors. This direct-coupled actuator is engineered for a 90-second runtime and a rapid 15-second spring return, making it a critical component for building automation and air volume control.
Key Benefits:- High Torque Capacity: Delivers 160 lb-in (18 Nm) of force, suitable for large dampers and high-pressure HVACR environments.
- Fail-Safe Security: Mechanical spring return ensures dampers reach a safe position during power loss in just 15 seconds.
- Precision Control: Modulating 0-10 VDC input with adjustable span and offset allows for fine-tuned air flow management.
- Durability: NEMA 2 / IP54 rated die-cast aluminum housing protects internal components in demanding commercial mechanical rooms.
- Flexible Integration: Integrated dual auxiliary switches (adjustable) provide easy signaling for end-of-travel status or sequence proofing.
What is the maximum shaft size the GCA164.1U can accommodate?
The patented self-centering shaft coupling is designed to grip round or square shafts up to 1 inch (25 mm) in diameter, ensuring a secure, slip-free connection.
Does this model include feedback for a BMS?
Yes, the GCA164.1U provides a 2-10 VDC position feedback signal, allowing your building management system to monitor the exact damper position in real-time.
Can the auxiliary switches be adjusted in the field?
Absolutely. The dual auxiliary switches are independently adjustable, allowing technicians to set specific trigger points for external equipment or status monitoring.
