Johnson Controls M9203-GGA-2Z Actuator

The Johnson Controls M9203-GGA-2Z is a high-performance spring return direct coupled actuator designed for precise proportional control in HVAC systems. Engineered for damper actuator applications, this unit provides 27 lb-in torque (3 Nm) and is compatible with 24Vac/Vdc power sources. The M9203-GGA-2Z supports multiple input signals, including 0-10Vdc, 2-10Vdc, and 4-20mA (with a 500 Ohm resistor), ensuring seamless integration with diverse building automation systems. This model features a 90-second power-on run time and a reliable mechanical spring return for fail-safe operation during power loss. To streamline installation for contractors, it comes equipped with a 120" plenum cable and 1/2" conduit connectors, meetng rigorous code requirements for air handling spaces. The M9203-GGA-2Z is an essential component for modulating airflow in medium-sized dampers and mechanical equipment.

Key Benefits

• Versatile Control: Supports modulating control via 0-10Vdc or 2-10Vdc signals for high-precision air management.
• Reliable Fail-Safe: Integrated spring return mechanism ensures the damper moves to a safe position during emergency shutdowns.
• Broad Compatibility: The direct coupled design fits standard round and square shafts, reducing the need for specialized linkages.
• Project Ready: Includes a factory-installed 120-inch plenum-rated cable to simplify wiring in restricted or high-clearance areas.
• Robust Build: Designed to withstand the rigors of commercial mechanical rooms while maintaining consistent proportional accuracy.

Common Questions

Can the M9203-GGA-2Z handle 4-20mA signals?
Yes, this actuator can process a 4-20mA control signal when utilized with an external 500 Ohm resistor to convert the signal to 2-10Vdc.

What is the maximum damper size for 27 lb-in torque?
Generally, 27 lb-in is sufficient for dampers up to 6.75 square feet, though actual requirements depend on the damper manufacturer's friction and pressure ratings.

How do I change the direction of the spring return?
The return direction (Normally Open or Normally Closed) is determined by how the actuator is mounted to the damper shaft; simply flip the unit to reverse the fail-safe orientation.
