Description
Overview
The Johnson Controls M9102-AGA-3S is a 24Vac non-spring return direct coupled actuator engineered for reliable damper control in commercial HVAC and building automation applications. Featuring floating control without timeout, this actuator delivers precise, repeatable positioning for air handling units, VAV systems, and other damper-driven equipment.
Key Features
- 24Vac floating control signal — compatible with standard building automation and DDC controllers
- No timeout function — actuator holds its last commanded position without automatic reset
- 18 lb-in (2 Nm) torque output — suitable for small to medium damper applications
- 30-second full-stroke travel time — smooth, controlled damper movement
- Non-spring return design — maintains position on power loss without spring force
- Direct coupled mounting — attaches directly to damper shaft for simplified installation
- Screw terminal wiring connections — secure, tool-friendly field wiring
Application
Ideal for use with zone dampers, mixing boxes, and air handling unit dampers in commercial and light industrial HVAC systems. The non-spring return configuration is well-suited for applications where fail-in-place operation is acceptable or preferred.
