Johnson Controls M9310-HGA-2 Electric Actuator

If you are looking for a reliable, non-spring return solution for damper or valve control, the Johnson Controls M9310-HGA-2 is the current standard for high-efficiency HVAC actuator replacement. This unit is the direct, drop-in successor for legacy models including the M9109-GGA-2, M9106-IGA-2, M9106-AGA-2, and M9109-AGA-4. Built with a brushless DC motor managed by an onboard microprocessor, it delivers a consistent 90-second runtime regardless of load or torque fluctuations up to its 90 lb-in rating. This 24V damper actuator features universal input compatibility, handling on/off, floating, or proportional 0(2)-10 VDC signals with ease. The integrated 120-inch plenum cable (CMP rated) ensures simplified field wiring in environmental air spaces without additional conduit in many jurisdictions. For precise control, the M9310-HGA-2 includes automatic signal input detection and electronic stall detection, which prevents motor burnout by stopping rotation if an obstruction is encountered, eliminating the need for fragile mechanical limit switches.

• Direct Replacement: Streamlines retrofits for older Johnson Controls M9100 series actuators without needing complex linkage kits.
• Universal Control Input: Operates on 24 VAC/VDC and supports proportional control, floating, and on/off signals in a single SKU.
• Self-Calibrating Logic: Features adjustable span and offset for the 0-10V signal, ensuring the actuator stroke perfectly matches the damper’s physical limits.
• Durable Construction: Rated for 100,000 full stroke cycles and 2.5 million repositions, with a NEMA 5/IP54 enclosure for protection against dust and moisture.
• Efficient Footprint: Compact design allows for installation in tight mechanical headers or VAV boxes where space is a premium.

How do I configure the M9310-HGA-2 for 4-20 mA control?
While the unit is out-of-the-box ready for 0-10 VDC, you can easily adapt it for 4-20 mA proportional control by adding a field-furnished 500-ohm resistor across the input terminals.

What happens if the damper jams during operation?
The integrated electronic stall detection monitors motor rotation. If the actuator detects a stall anywhere in the rotation range, it cuts power to the motor to prevent gear damage and thermal overload.

Can I use this actuator to replace a valve motor?
Yes. The M9310-HGA-2 is designed for versatility and can be converted to a valve actuator when used with the appropriate M9310-500 valve linkage kit.
