Johnson Controls M9220-HGA-3 Spring Return Direct Coupled Actuator, 177 lb-in

Description

The Johnson Controls M9220-HGA-3 is a high-performance spring return direct coupled actuator engineered for precise, reliable damper control in commercial HVAC and building automation systems. Featuring a robust 177 lb-in torque output and a 150-second power-on run time, this actuator delivers the muscle needed for demanding applications while ensuring safe spring-return failsafe positioning on power loss.

Versatile Input Signal Compatibility

The M9220-HGA-3 accepts a wide range of control signals, making it compatible with virtually any building automation or DDC controller:

• 24 Vac / 24 Vdc power supply
• 0–10 Vdc proportional control
• 2–10 Vdc proportional control
• 0–20 mA and 4–20 mA with integrated 500 Ohm resistor

Proportional Control with Adjustable Zero and Span

The actuator’s proportional operation with adjustable zero and span allows field technicians to fine-tune the control range to match exact system requirements — eliminating the need for additional signal conditioning hardware and reducing commissioning time.

Spring Return Failsafe Operation

Built-in spring return technology automatically drives the actuator to its failsafe position whenever power is interrupted. This critical safety feature helps protect building occupants and equipment during power outages or system faults.
