Nordyne 626617 Limit Switch
The Johnson Controls M9108-GGA-2 is a robust non-spring return rotary actuator designed for professional-grade HVACR applications. Engineered to deliver 70 lb-in torque (8 Nm), this unit is ideal for positioning damper actuators and valves in VAV boxes or small-to-medium air handling systems. It operates on a standard 24 VAC/VDC power supply and utilizes a proportional control signal (0-10 VDC or 0-20 mA) for precise air volume management. Featuring a brushless DC motor, the M9108-GGA-2 ensures consistent performance with electronic stall detection, which protects the gear train by deactivating the motor if an obstruction is encountered. The integrated magnetic clutch and manual gear release button allow for fast field adjustments and manual positioning without power. The enclosure includes an anti-rotation bracket and a universal U-bolt clamp, compatible with round shafts up to 3/4 inch or square shafts up to 5/8 inch, streamlining the replacement process for contractors in the field.
Key Benefits:
- Precise Proportional Control: Accepts 0(2)-10 VDC or 0(4)-20 mA signals for exact damper positioning and high-resolution control.
- Simplified Installation: The direct-mount design with a universal coupler eliminates the need for complex linkages.
- Enhanced Reliability: Electronic stall detection and a rugged brushless DC motor extend the operational life cycle under demanding conditions.
- Versatile Compatibility: Mounts to various shaft sizes and shapes, making it a "truck stock" essential for HVAC automation repairs.
- Manual Override: A dedicated gear release button enables quick manual overrides for commissioning or emergency troubleshooting.
Common Questions:
- Can this actuator be used for both 0-10V and 4-20mA signals? Yes, the M9108-GGA-2 is designed to handle both voltage and current proportional inputs, typically selected via internal jumpers or wiring configurations.
- What is the typical rotation time for this model? This actuator has a nominal rotation time of 25 to 50 seconds for a full 90-degree stroke, depending on the specific load and frequency.
- Is this unit suitable for outdoor dampers? This model is rated for indoor use; for outdoor air dampers in cold climates, we recommend evaluating a spring-return alternative to ensure fail-safe closure.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
