Siemens GCA163.1P OpenAir 24V 0-10VDC Spring Return Damper Actuator 160 lb-in
NC012a
Siemens GCA163.1P OpenAir spring-return electronic damper actuator delivers 160 lb-in (18 Nm) of torque with 24 VAC/DC power and 0–10 VDC modulating control for commercial HVAC and building-automation applications. This adjustable span/offset model combines fail-safe spring return, direct-coupled mounting, manual override and position feedback in Siemens' rugged OpenAir actuator platform.
Designed for constant- or variable-air-volume HVAC installations including return-air, mixed-air, exhaust-air, and face-and-bypass damper applications. The spring-return mechanism is designed to move the damper to a fail-safe position upon loss of power. Siemens literature describes the GCA series as using a brushless DC motor, self-centering shaft coupling and all-metal housing.

Manufacturer Background
Siemens traces its history to 1847, when Werner von Siemens and Johann Georg Halske established Siemens & Halske in Berlin. It developed from an early electrical-engineering enterprise into a major international technology company with extensive operations in electrification, industrial automation and smart-building technology. The OpenAir line is part of Siemens' long-running HVAC/building-controls product portfolio.
Country of manufacture of this actuator: USA, confirmed by both the actuator and factory-box labels.
Age / Release Information
Your box carries the date code 20171204, which I interpret as December 4, 2017. Therefore, this particular unit is about 8 years 9 months old.
The GCA product family itself predates your unit by several years; Siemens technical literature documents the GCA163.1P before 2017.
