Description
The Johnson Controls M9208-BAA-3 is a robust, two-position spring return direct coupled actuator engineered for reliable damper and valve control in commercial HVAC applications. Operating on 120 Vac power, this actuator delivers dependable two-position (open/close) actuation with automatic spring return to the fail-safe position upon power loss — a critical safety feature for air handling, ventilation, and building automation systems.
With a powerful 70 lb-in torque output, the M9208-BAA-3 handles demanding damper loads with ease. Its 55–71 second power-on run time provides smooth, controlled actuation that protects connected equipment. The unit ships complete with a 48-inch appliance cable featuring an integral 3/8″ flexible metal conduit (FMC) connector, simplifying installation and ensuring a secure, code-compliant wiring connection right out of the box.
Designed for direct shaft coupling, this actuator mounts directly to damper shafts without the need for additional linkage hardware, reducing installation time and potential points of failure.
