Johnson Controls M9220-GGA-3 Actuator

The Johnson Controls M9220-GGA-3 is a high-torque, proportional spring return actuator engineered for precise control of dampers and valves in commercial HVAC systems. Delivering a robust 177 lb-in (20 Nm) torque, this direct-coupled actuator utilizes a brushless DC motor and electronic stall detection to ensure reliable performance without the need for end-of-rotation limit switches. It supports a wide range of control signals, including 0-10 VDC, 2-10 VDC, and 4-20 mA (with the included 500-ohm resistor), making it a versatile solution for complex building automation integrations. The unit features a 150-second power-on run time and a dependable mechanical spring return for fail-safe positioning during power loss. Designed for the field, the M9220-GGA-3 includes a 48-inch 18 AWG appliance cable, a manual override crank for commissioning, and a reversible mounting design to accommodate diverse installation requirements in demanding environments.

• Versatile Control Compatibility: Seamlessly integrates with 24VAC/VDC systems and responds to multiple analog input signals for precise modulation.
• High Torque Capacity: The 177 lb-in rating provides sufficient power for large-scale damper and valve assemblies.
• Simplified Installation: Features a direct-coupled design and pre-wired 48-inch leads to reduce labor time on the job site.
• Fail-Safe Reliability: Integrated spring return mechanism ensures the system defaults to a safe position during emergency shutdowns.
• Long-Term Durability: Rated for 60,000 full-stroke cycles and 1.5 million repositions, minimizing call-backs and maintenance overhead.

What is the fail-safe direction for the M9220-GGA-3?
The spring return direction is determined by the orientation of the actuator on the shaft. By flipping the actuator, you can select either clockwise (CW) or counterclockwise (CCW) fail-safe operation.

Can I use this for 4-20 mA applications?
Yes, the M9220-GGA-3 is compatible with 4-20 mA control signals when utilized with the factory-supplied 500-ohm resistor across the input leads.

Does this unit require a separate linkage for damper mounting?
No, this is a direct-coupled actuator designed to mount directly onto a 3/8-inch to 3/4-inch round shaft or a 3/8-inch to 5/8-inch square shaft using the standard coupler.
