M9104-IGA-3S Johnson Controls Damper Actuator

Overview

The Johnson Controls M9104-IGA-3S is a reliable, non-spring return direct-coupled electric actuator designed for precise damper and valve control in commercial HVAC systems. Operating on a 24 VAC power supply, this synchronous motor-driven unit features floating or two-position control with an automatic shut-off (timeout) function that prevents motor burnout by cutting the drive signal after a period of inactivity. Its compact design allows for easy direct-mount installation in tight spaces without the need for external linkages.

Features

• Floating or two-position control with built-in automatic shut-off timeout logic to eliminate the need for external end-switches
• Synchronous drive technology provides constant rotation time independent of the load
• M3 screw terminal block connections for secure and fast field installation
• Direct-mount installation with a single-screw coupler fits round or square shafts
• Manual gear release and magnetic clutch provide over-torque protection
• Whisper-quiet operation with a low 35 dBA nominal noise rating
• Long operational life rated for over 100,000 full-stroke cycles
