Siemens Building Technology GCA126.1P Actuator
The Siemens GCA126.1P is a high-torque spring return rotary electronic actuator designed specifically for the rigorous demands of HVAC systems and air handling units. Operating on a 24V AC/DC supply, this 142 lb-in damer actuator provides reliable two-position control (On/Off) for dampers up to 34 sq. ft. Built with a rugged die-cast aluminum housing, it ensures durability in mechanical rooms and plenum environments. This model features integrated dual auxiliary switches for precise position signaling and comes equipped with a plenum-rated cable for direct installation. The mechanical spring return system ensures a fail-safe position upon power loss, a critical requirement for smoke and isolation damper applications. Engineers often specify the Siemens OpenAir GCA series for its self-centering shaft adapter, which simplifies mounting on round or square shafts and minimizes installation time for field contractors.
- High Torque Output: Delivers 142 lb-in (16 Nm) of torque for effective control of large dampers or high-pressure systems.
- Fail-Safe Reliability: Robust mechanical spring return ensures the damper reaches its defined safety position during power interruptions.
- Integrated Signaling: Two built-in auxiliary switches allow for seamless integration with BMS feedback loops and safety interlocks.
- Plenum Rated: Includes 3-foot pre-terminated plenum cable, meeting fire code requirements for installation in environmental air spaces.
- Direct Mount Design: Features a self-centering shaft coupling that accommodates shaft diameters from 3/8-inch to 1-inch, reducing the need for additional linkage kits.
Common Questions
What is the typical stroke time for the GCA126.1P?
Under normal powered operation, the motor has a 90-second run time. In a power-loss scenario, the spring return mechanism typically closes the damper in less than 15 seconds.
Can this actuator be used in bypass damper applications?
Yes, it is suitable for bypass and zone control applications, provided the damper dimensions and air velocity do not exceed the 142 lb-in torque rating of the motor.
Is the GCA126.1P compatible with both AC and DC power systems?
Precisely. This actuator is designed to operate on a 24V AC or 24V DC nominal power supply, providing flexibility for various control transformer configurations.
