Johnson Controls M9220-BGA-3 Actuator

The Johnson Controls M9220-BGA-3 is a high-torque spring return damper actuator designed for the precise positioning of air dampers and valves in commercial HVAC systems. Delivering a robust 177 lb-in (20 Nm) torque, this direct-coupled actuator provides on/off (two-position) control with a versatile power input compatible with both 24 VAC and 24 VDC systems. As the direct replacement for the M9216-BGA-2YK, this unit features a microprocessor-controlled brushless DC motor that ensures a consistent power-on run time of 24-57 seconds, regardless of the load. The spring return mechanism activates upon power loss, returning the damper to its fail-safe position in under 15 seconds. Built with a NEMA 2 (IP54) aluminum enclosure and an electronic stall detection system, this actuator is engineered for longevity in demanding environments, eliminating the need for external end-switches by deactivating the motor when an overload is sensed. Installation is streamlined via the 48-inch 18 AWG appliance cable and a reversible mounting design that allows for fail-safe operation in either rotation direction.

• High Output Torque: Provides 177 lb-in (20 Nm) of force, suitable for large dampers and high-pressure applications.
• Seamless Retrofit: Engineered as the M9216-BGA-2YK replacement, ensuring a perfect fit with existing Johnson Controls damper linkages.
• Intelligent Motor Protection: Features electronic stall detection to prevent motor burnout during mechanical obstructions.
• Fail-Safe Reliability: Mechanical spring return ensures dampers close or open during power failures to maintain building safety.
• Universal Installation: The direct mount design supports round shafts from 1/2" to 3/4" and square shafts from 3/8" to 1/2".

Is the M9220-BGA-3 compatible with my current 24V system?
Yes, this two-position actuator operates on a 24 VAC at 50/60 Hz or 24 VDC power supply, making it compatible with standard HVAC control circuits.

Can I manually adjust the damper position without power?
This model includes an integrated manual override crank, allowing technicians to manually position the damper actuator hub for testing or emergency operation.

Does this unit include auxiliary switches?
The M9220-BGA-3 is the standard model without auxiliary switches. If your application requires end-stop feedback, please verify the specific model suffix required for your project.
