Johnson Controls M9116-AGA-2 Actuator

The Johnson Controls M9116-AGA-2 is a professional-grade non-spring return direct coupled actuator designed for the precise positioning of air dampers and valves in commercial HVACR systems. Delivering a robust 140 lb-in torque, this electric motor actuator is engineered for high-reliability applications, featuring electronic stall detection that protects the motor by deactivating power when a blockage is sensed. Whether you are managing return air dampers, exhaust systems, or variable volume fans, the M9116-AGA-2 offers versatile floating control or two-position logic to meet exacting site requirements.

Built for the technician, this 24Vac/Vdc damper actuator utilizes a direct mount design that eliminates the need for complex damper linkages, significantly reducing commissioning time. Electrical connections are handled via integrated screw terminals, accommodating 22 to 14 AWG wiring. With a travel time of 70 to 115 seconds and a jumper-selectable rotation direction, this unit provides the flexibility needed for field adjustments. Its NEMA 2 (IP42) rated housing and wide operating temperature range ensure stable performance in demanding mechanical room environments.

• High Torque Output: Provides 140 lb-in (16 N·m) of running torque to handle large dampers and heavy valve assemblies.
• Simplified Installation: Direct coupled universal mounting supports round shafts up to 3/4 inch and square shafts up to 5/8 inch without external linkages.
• Motor Protection: Integrated electronic stall detection increases component longevity by preventing motor burnout during mechanical failure or obstruction.
• Manual Override: Features a spring-loaded gear release button for easy manual positioning and rapid system setup.
• Dual Power Compatibility: Flexible 24Vac or 24Vdc operation allows for integration into various control loops.

Can the M9116-AGA-2 be used in tandem?
Yes, these actuators can be stacked for tandem applications to double the torque output, provided the master/slave configuration is properly wired for synchronized control.

What happens if the motor stalls?
The internal stall detection circuitry will automatically cut power to the motor if it detects an obstruction, protecting the gears and electronics from damage without requiring external switches.

Does this unit have auxiliary switches?
The AGA-2 model does not include auxiliary switches or feedback potentiometers. If your application requires end-stop signals or position feedback, look to the AGC or AGD models in the M9116 series.
