Siemens Building Technology GMA131.1U Actuator
The Siemens Building Technology GMA131.1U is a specialized OpenAir electronic damper actuator engineered for commercial HVAC applications. This 24V spring return actuator provides 62 lb-in torque (7 Nm), making it an ideal choice for managing return air, mixed air, and exhaust dampers in both constant and variable air volume (VAV) systems. Designed with three-position control (floating), it allows for precise positioning while ensuring a reliable fail-safe return to the "0" position during power loss. The brushless DC motor technology prevents burnout by providing internal stall protection throughout the 90-degree rotation. For the field technician, the self-centering shaft coupling and 90-second runtime streamline the commissioning process, while the NEMA 1 (IP54) die-cast aluminum housing ensures durability in demanding mechanical rooms. This unit is built for direct-coupled rotary damper mounting, offering a robust solution for contractors focused on long-term performance and system integrity.
Key Benefits:- Fail-Safe Protection: Reliable bi-directional spring return ensures dampers reach a safe state during power interruptions.
- Stall Protection: Integrated brushless DC motor technology eliminates the need for limit switches by protecting against mechanical blockages.
- Precise Control: Supports 3-position floating control for versatile airflow management in HVACR systems.
- Contractor-Friendly Install: Features a self-centering shaft coupling and a 3-foot pre-wired cable to reduce labor time on the job site.
- What is the torque rating of the GMA131.1U? This actuator delivers a rated torque of 62 lb-in, suitable for dampers up to approximately 15 square feet.
- Does this model include auxiliary switches? The standard GMA131.1U does not include auxiliary switches; if your sequence of operations requires position feedback, verify the specific sub-model suffix.
- Can it be used with 24V DC? Yes, this unit is compatible with both 24 VAC and 24 VDC power supplies, providing flexibility for various controller types.
