Siemens Building Technology GCA126.1U Actuator
The Siemens GCA126.1U is a heavy-duty OpenAir spring return actuator engineered for 2-position control in demanding HVAC systems. This 24VAC/DC damper actuator delivers a robust 160 lb-in torque (18 Nm), making it an industry standard for managing return air, exhaust, and face-and-bypass dampers in high-capacity air handling units. Designed for fail-safe reliability, the bi-directional spring return ensures dampers reach a secure position during power loss in under 15 seconds. This model features dual auxiliary switches (SPDT) for position signaling and integration into safety interlocks. The self-centering shaft coupling accommodates various shaft sizes, significantly reducing installation time for field technicians. With a durable NEMA 2 die-cast aluminum housing and brushless DC motor technology, this actuator provides stall protection and quiet operation without the need for limit switches, ensuring long-term performance in commercial and industrial mechanical applications.
Key Benefits:- High Torque Capacity: Rated at 160 lb-in (18 Nm) torque to reliably drive large dampers in high-velocity systems.
- Fail-Safe Protection: Reliable mechanical spring return fail-safe ensures system safety during emergency power outages.
- Integrated Auxiliary Switches: Includes two built-in dual auxiliary switches for seamless end-switch signaling and status feedback.
- Efficient Installation: Features a self-centering shaft coupling and a 3-foot pre-wired cable to streamline field replacement.
- Energy Efficient: Utilizes brushless DC motor technology for low power consumption and stall protection.
- What is the typical runtime for this actuator? The Siemens GCA126.1U features a 90-second motor drive time and a rapid mechanical spring return time of less than 15 seconds.
- Can this actuator be used with 24VDC power? Yes, this 2-position damper actuator is compatible with both 24VAC and 24VDC power supplies.
- How do I adjust the auxiliary switches? The switches are factory-set but can be field-adjusted to signal specific damper positions according to the system's operational requirements.
