M9203-GGA-2Z Johnson Controls Actuator

Overview

The Johnson Controls M9203-GGA-2Z is a high-performance proportional electric spring-return actuator designed for precise damper control in commercial and industrial HVAC applications. It provides 27 lb-in (3 Nm) of rated torque and features a 90-second constant runtime. A mechanical spring-return system ensures the actuator returns to a fail-safe position upon a loss of power.

Features

• Proportional control for accurate, modulating damper positioning
• Spring return fail-safe mechanism for enhanced operational safety
• Direct-coupled design that mounts directly to the damper shaft without external linkages
• Microprocessor-controlled brushless DC motor with electronic stall detection to protect against overload
• 120-inch plenum-rated cable with 1/2-inch conduit connectors for code-compliant installation

Specifications

• Torque: 27 lb-in (3 N-m) running and spring return
• Supply Voltage: 24 VAC at 50/60 Hz or 24 VDC
• Input Signal: 0 to 10 VDC, 2 to 10 VDC, or 0(4) to 20 mA with a 500 ohm resistor
• Feedback Signal: 0 to 10 VDC or 2 to 10 VDC
• Runtime: 90 seconds constant for power on, 12 to 22 seconds for spring return

Applications

• Variable air volume (VAV) systems
• Air handling units (AHUs)
• Economizer and outside air damper control
• Commercial building automation and digital control (DDC) systems
• Exhaust, return, and supply air dampers
