Johnson Controls M9116-GGA-2 Actuator

The Johnson Controls M9116-GGA-2 Actuator is a professional-grade, non-spring return direct coupled actuator engineered for precise control in commercial HVACR systems. Delivering a robust 140 lb-in torque (16 Nm), this unit is designed to drive dampers or valves without the need for complex linkages. It operates on a versatile 24Vac/Vdc power supply and supports multiple proportional control signals, including 0-10Vdc, 2-10Vdc, and 4-20mA (via the included 500-ohm resistor). With a travel time of 70 to 115 seconds for a 90-degree rotation, it ensures stable modulation and eliminates hunting. Built-in electronic stall detection protects the motor by deactivating it when an obstruction is sensed, while the manual gear release allows for quick field adjustments. The screw terminals simplify field wiring, and the dual-scale cover allows for easy visual verification of the stroke position in any orientation.

• High Torque Output: Provides 140 lb-in of torque, sufficient for large damper areas and high-pressure valve applications.
• Universal Compatibility: Mounts directly to round shafts up to 3/4 inch or square shafts up to 5/8 inch, reducing installation labor.
• Advanced Signal Handling: Jumper-selectable 0-10Vdc or 4-20mA inputs provide flexibility for building automation system (BAS) integration.
• Enhanced Reliability: Features a brushless DC motor and stall detection to prevent motor burnout during mechanical workspace failures.
• Feedback Precision: Includes a 0(2)-10Vdc feedback signal for accurate closed-loop position monitoring at the controller.

Common Questions

Can the M9116-GGA-2 be used in tandem?
Yes, two of these modulating damper actuators can be mounted in tandem to double the effective torque output to 280 lb-in on a single shaft.

How do I change the direction of rotation?
The rotation direction (clockwise or counter-clockwise) is easily adjusted via an internal jumper, allowing you to match the fail-safe or primary orientation of the damper blades.

What type of wiring is required for the 4-20mA signal?
When using a current signal, the included 500-ohm resistor must be installed across the input terminals to convert the signal to the required voltage range for the logic board.
