Siemens Building Technology GCA156.1U Actuator
The Siemens GCA156.1U is a heavy-duty OpenAir spring return electronic damper actuator engineered for precise modulating control in demanding commercial HVAC systems. This 24V AC/DC unit delivers a robust 142 lb-in torque (160 lb-in nominal) to effectively manage large dampers in VAV terminals, air handlers, and mixed-air applications. Built with brushless DC motor technology, it features integrated stall protection to prevent motor burnout, ensuring long-term operational reliability without the need for limit switches. This model supports 0/2-10 VDC modulating signals and includes dual auxiliary switches for convenient position signaling and interlocking with peripheral equipment. Designed for technicians who prioritize efficiency, the patented self-centering shaft coupling accommodates various shaft sizes up to 1 inch, dramatically reducing installation time and eliminating common alignment issues. The rugged NEMA 2 die-cast aluminum housing provides professional-grade durability for mechanical rooms and plenums.
Key Benefits- Fail-Safe Performance: Mechanical spring return fail-safe ensures dampers return to a predetermined position during power loss for critical safety.
- Precise Modulation: Provides smooth 0-10V or 2-10V control for accurate airflow regulation and optimized building automation efficiency.
- Integrated Signaling: Features two auxiliary switches (S1, S2) that are field-adjustable for custom feedback and automation sequences.
- Broad Compatibility: The direct-coupled mounting design fits round shafts up to 1" or square shafts up to 3/4", offering maximum versatility on the job site.
- Manual Override: Allows for manual positioning during commissioning or maintenance cycles without requiring electrical power.
Is the GCA156.1U compatible with 4-20mA signals?
Yes, while it primarily accepts 0-10 VDC, it can be configured for 4-20mA control using a 500-ohm resistor across the input leads.
What is the typical runtime for this actuator?
Under normal operating conditions at 60Hz, the drive time is approximately 90 seconds, with a spring return closing time of less than 15 seconds.
Can I mount this in any orientation?
The NEMA 2 rating permits mounting in several orientations; however, vertical mounting is recommended for maximum environmental protection against moisture.
