Johnson Controls M9220-GGA-YK30 Actuator

The Johnson Controls M9220-GGA-YK30 is a high-torque electric spring return actuator engineered for precise proportional control of dampers and valves in commercial HVACR systems. Operating on 24 VAC power, this direct-mount unit delivers a robust 177 lb-in (20 N·m) of running and spring-return torque. Designed for versatile field integration, it supports standard 0(2) to 10 VDC or 0(4) to 20 mA analog signals, providing accurate modulation with approximately 120 steps of control. The brushless DC motor, managed by an integrated microprocessor, ensures a constant 150-second drive time regardless of load, while the mechanical spring return reliably closes or opens the device in under 15 seconds during power loss. Encased in a NEMA 2 (IP54) aluminum housing, the M9220-GGA-YK30 features electronic stall detection and a manual override with auto-release, making it a dependable choice for contractors managing high-demand air handling units and complex hydronic circuits.

• Universal Compatibility: Accepts 0-10 VDC, 2-10 VDC, and 4-20 mA control signals for seamless integration with most HVAC automation systems.
• High Torque Capacity: Provides 177 lb-in of torque, with the ability to mount up to three units in tandem for 531 lb-in applications.
• Fail-Safe Reliability: Mechanical spring return ensures equipment returns to a safe position during emergency shutdowns or power failures.
• Simplified Installation: Features a reversible mounting design and a universal shaft clamp for round or square damper shafts without needing additional linkages.
• Internal Protection: Microprocessor-controlled electronic stall detection protects the motor from burnout if the damper or valve is obstructed.

What control signal does the M9220-GGA-YK30 use?
This model is a proportional actuator that typically utilizes a 0 to 10 VDC signal. It can also be configured for 2 to 10 VDC or 4 to 20 mA signals using the onboard selector switch and a field-furnished resistor if required.

Can this actuator be used on both dampers and valves?
Yes, it is designed for direct-mount applications on dampers and can be adapted for valve control with the appropriate Johnson Controls linkage kits.

Does it include a feedback signal?
Yes, it provides a 0(2) to 10 VDC feedback signal to the controller to confirm the exact position of the actuator hub.
