Johnson Controls M9116-HGA-2 Actuator

The Johnson Controls M9116-HGA-2 is a high-torque non-spring return direct coupled actuator engineered for precise positioning of air dampers and valves in commercial HVACR systems. Delivering a robust 140 lb-in torque, this proportional control actuator is compatible with 24 VAC/VDC power supplies and accepts a wide range of input signals, including 0-10 VDC and 0-20 mA (with the integrated 500-ohm resistor). Designed for versatility, it features adjustable start and span (zero and span) settings, allowing technicians to calibrate the 70-115 second travel time and rotation range to specific application requirements. The unit’s direct-mount design eliminates the need for complex damper linkages, while the screw terminals ensure secure electrical connections for 22 to 14 AWG wiring. With electronic stall detection and a manual gear release, this actuator provides reliable performance and simplified commissioning for modulating damper control and valve automation.

• Flexible Control: Supports multiple analog input signals (0-10V, 0-20mA) with field-adjustable start/span for custom sequencing.
• High Torque Output: Provides 140 lb-in (16 Nm) of running torque, capable of 280 lb-in when used in tandem applications.
• Simplified Installation: Features a self-centering shaft coupler that fits round shafts up to 3/4" and square shafts up to 5/8".
• Durability: Equipped with a NEMA 2 (IP42) rated enclosure and stall detection to protect the motor from damage during obstructions.
• Precise Feedback: Includes a 0-10 VDC feedback signal for accurate position monitoring in closed-loop systems.

What is the difference between the M9116-HGA-2 and the GGA models?
The HG models, like the M9116-HGA-2, include adjustable start and span potentiometers, whereas the GG models are fixed. This allows the HGA-2 to be calibrated for specific signal ranges (e.g., 2-10V) or sequenced with other actuators.

Can this actuator be used on outdoor dampers?
While it features a NEMA 2 enclosure, it is a non-spring return actuator. For outdoor air dampers in cold climates, a spring-return model is typically recommended to ensure the damper closes during a power loss to prevent coil freezing.

Does it require a separate linkage kit for damper mounting?
No, this is a direct coupled actuator. It mounts directly onto the damper shaft using a U-bolt clamp, significantly reducing installation time by eliminating external linkages.
