Johnson Controls M9102-IGA-3S Direct Coupled Actuator Overview
The Johnson Controls M9102-IGA-3S is a reliable, non-spring return direct coupled actuator engineered for precise damper and valve control in commercial HVAC systems. Operating on 24Vac power, this actuator supports both floating control and two-position control modes with a built-in timeout feature, offering versatile integration into a wide range of building automation and HVAC control applications. Its direct-coupled design eliminates the need for crank arms or linkages, simplifying installation and reducing maintenance requirements.
Key Features
- 24Vac operating voltage for compatibility with standard HVAC control systems
- Floating control or two-position control operation with timeout functionality
- 18 lb-in torque output for dependable damper and valve actuation
- 30-second travel time for smooth, responsive positioning
- Non-spring return design — maintains last position on power loss
- Direct coupled mounting — no linkage hardware required
- Screw terminal wiring connections for fast, secure field wiring
- Compact, robust construction suited for commercial HVAC environments
Control Modes
The M9102-IGA-3S supports two industry-standard control modes, giving installers and system designers flexibility:
- Floating Control: Allows incremental positioning via open/close signals, ideal for modulating applications
