Johnson Controls M9220-GGC-3 Actuator

The Johnson Controls M9220-GGC-3 Actuator is a heavy-duty, spring return direct coupled actuator providing 177 lb-in (20 Nm) of torque for managing large dampers and valves. Engineered for precision in HVACR applications, this proportional damper actuator supports a versatile control range including 0-10Vdc, 2-10Vdc, and 4-20mA signals with the integrated 500 Ohm resistor. The microprocessor-controlled brushless DC motor ensures a constant 150-second power-on run time regardless of the load, while the mechanical spring return provides a reliable 20-second fail-safe stroke upon power loss. For enhanced system integration, the M9220-GGC-3 features two built-in SPDT auxiliary switches that allow for end-stop position signaling or auxiliary equipment interlocking. The 48-inch appliance cable simplifies 24Vac/Vdc field wiring, while the NEMA 2 rated aluminum enclosure and reversible mounting design make it a robust choice for contractors requiring high-torque HVAC actuator performance in demanding environments.

Key Benefits:

• Universal Control Compatibility: Seamlessly integrates with 0-10Vdc and 4-20mA controllers for high-accuracy proportional modulation.
• Dual Auxiliary Switches: Features two SPDT switches for reliable end-position feedback and safety interlocking without extra components.
• Direct Mount Installation: Fits 1/2" to 3/4" round shafts or 3/8" to 1/2" square shafts without the need for complex damper linkages.
• Fail-Safe Reliability: The spring return actuator mechanism ensures the damper moves to a predefined safety position during power outages.
• Brushless DC Motor: Delivers consistent timing and extended service life through advanced electronic stall detection.

Common Questions:

How do I wire the M9220-GGC-3 for a 4-20mA signal?
Connect the 4-20mA control signal across the black (common) and orange (input) wires while utilizing the factory-included 500 Ohm resistor to convert the current to a voltage signal for the internal processor.

Can this actuator be mounted for both CW and CCW spring return?
Yes. The reversible mounting design allows the Johnson Controls M9220-GGC-3 to be flipped, enabling you to select the fail-safe direction (clockwise or counterclockwise) based on the application requirements.

What is the purpose of the manual override crank?
The included manual crank allows technicians to position the actuator hub without power for easier installation and commissioning. The hub automatically unlocks once 24V power is applied.
