Johnson Controls M9203-GGA-2Z Spring Return Direct Coupled Actuator Overview
The Johnson Controls M9203-GGA-2Z is a high-performance proportional spring return direct coupled actuator engineered for precise damper control in commercial and industrial HVAC applications. Designed for reliable, fail-safe operation, this actuator returns to its spring-set position upon loss of power, making it ideal for critical air-handling and ventilation systems.
Key Features
- Proportional control for accurate, modulating damper positioning
- Spring return fail-safe design ensures damper returns to default position on power loss
- Direct coupled mounting — no crank arm or linkage required for simplified installation
- 27 lb-in output torque for reliable operation across a wide range of damper sizes
- 90-second power-on run time for smooth, controlled actuation
- 120″ (10 ft) plenum-rated cable with 1/2″ conduit connectors for code-compliant wiring in air plenums
Electrical Specifications
- Supply voltage: 24 Vac / 24 Vdc
- Control signal inputs: 0–10 Vdc, 2–10 Vdc, (0)4–20 mA (with 500 Ohm resistor)
