Johnson Controls M9116-GGC-2 Actuator

The Johnson Controls M9116-GGC-2 is a robust non-spring return direct coupled actuator designed for the precise positioning of dampers and valves in larger HVAC systems. Delivering 140 lb-in torque, this unit operates on 24Vac/Vdc power and supports a versatile range of proportional control signals, including 0-10Vdc, 2-10Vdc, and 4-20mA (via the included 500-ohm resistor). Field technicians value this model for its 70-115 second travel time and integrated 2 SPDT auxiliary switches, which provide reliable feedback for end-of-stroke position or auxiliary equipment sequencing. This model serves as the direct replacement for the legacy DM24-140-A, utilizing screw terminals for secure electrical connections. Its synchronous motor ensures constant drive timing independent of load, making it a dependable choice for modulating airflow or water flow in complex building automation sequences.

Key Benefits

• Compatible with multiple control protocols, ensuring seamless integration with existing BMS controllers.
• High torque capacity enables the operation of damper areas up to 35 square feet.
• Dual integrated auxiliary switches reduce installation time for applications requiring position feedback.
• Designed for easy mounting on round shafts up to 3/4 inch or square shafts up to 5/8 inch.
• The manual override button allows for quick mechanical adjustments and simplified commissioning.

Common Questions

How do I wire the Johnson Controls M9116-GGC-2 for 4-20mA control?
To utilize a 4-20mA input signal, you must install the provided 500-ohm resistor across the input terminals to convert the current signal into a proportional voltage signal the actuator can process.

Can this model replace the older DM24-140-A actuator?
Yes, the M9116-GGC-2 is the direct replacement for DM24-140-A, maintaining similar footprint and torque specifications for a drop-in retrofit.

What is the function of the auxiliary switches on this actuator?
The two SPDT auxiliary switches are used to signal when the actuator reaches specific rotation points, allowing for the interlocking of fans, pumps, or other system components.
