Johnson Controls M9116-HGC-2 Actuator

The Johnson Controls M9116-HGC-2 Actuator is a heavy-duty, non-spring return direct coupled actuator engineered for precise control in commercial HVACR systems. Delivering a robust 140 lb-in torque, this unit is designed to drive dampers or valves without the need for complex linkages, significantly reducing installation time and mechanical failure points. It supports proportional control with a flexible input range, accepting 0-10 VDC or 0-20 mA signals, and includes a 500-ohm resistor for current loop applications. The "HG" series is specifically valued by technicians for its adjustable start and span, allowing for custom calibration of the control signal to match specific field requirements. Operating on 24VAC/VDC power, the M9116-HGC-2 features electronic stall detection to protect the motor geartrain and includes 2 SPDT auxiliary switches for end-stop signaling or external equipment interlocking. With a travel time of 70-115 seconds and a NEMA 2/IP42 rated enclosure, it provides reliable modulating control for large air handlers and terminal units.

• Enhanced Job-Site Flexibility: Jumper-selectable rotation direction and manual gear release simplify setup and manual positioning during commissioning.
• Precision Signal Calibration: Integrated adjustable zero and span potentiometers allow for precise sequencing and fine-tuning of the actuator's response to the controller.
• Superior Reliability: Built-in electronic stall detection deactivates the motor if an obstruction is met, preventing burnout and extending service life.
• Integrated Feedback: Features two built-in SPDT auxiliary switches that provide clear confirmation of damper position for building automation systems.
• Universal Mounting: Fits round shafts up to 3/4 inch and square shafts up to 5/8 inch for broad compatibility across various damper brands.

Common Questions

Can I use two M9116-HGC-2 actuators in tandem for higher torque?
Yes, these units support master/slave operation. When mounted in tandem using the appropriate linkage kit, two actuators can deliver up to 280 lb-in of torque for larger damper sections.

What is the purpose of the 0-10VDC feedback signal?
The feedback signal allows your building management system to monitor the actual position of the actuator in real-time, ensuring the damper is responding correctly to the control signal.

How do I adjust the rotation range?
The rotation range is mechanically adjustable from 0 to 90 degrees in 5-degree increments. Use the integrated manual gear release to set your limits without needing to power the unit.
