Description
Johnson Controls M9104-AGA-2S Direct Coupled Actuator Overview
The Johnson Controls M9104-AGA-2S is a 24VAC direct coupled damper actuator engineered for reliable floating control in commercial HVAC applications. Designed without a timeout function, this non-spring return actuator holds its last commanded position on power loss, making it ideal for applications where damper position retention is required. Its direct-coupled design eliminates the need for crank arms and linkages, simplifying installation and reducing maintenance.
Key Features
- 24VAC floating control signal — compatible with standard building automation and HVAC control systems
- 35 lb-in (4 Nm) torque output — suitable for a wide range of damper sizes and types
- 60-second full-stroke travel time for smooth, controlled damper positioning
- Non-spring return operation — retains last position on power loss, no return spring required
- Floating control without timeout — actuator responds precisely to open, close, and stop signals
- 48″ plenum-rated cable — meets plenum installation requirements for air-handling environments
- Direct coupled mounting — attaches directly to damper shaft without additional linkage hardware
