M9208-BGA-3G Johnson Controls Actuator

Overview

The Johnson Controls M9208-BGA-3G is a reliable, direct-mount electric spring-return actuator designed for control of dampers in HVAC systems. It operates on 24 VAC or 24 VDC power, providing two-position (on/off) control. It mounts directly to the damper shaft without the need for a linkage, and features an automatic mechanical spring return system that ensures a fail-safe position upon loss of power.

Features

• Direct-coupled design mounts directly to the shaft, eliminating the need for a damper linkage
• Reversible mounting design allows for either clockwise or counterclockwise fail-safe operation
• Double-insulated construction eliminates the requirement for an additional electrical ground connection
• Robust design with a life expectancy of at least 60,000 cycles
• Electronic stall detection safeguards the motor against damage throughout its rotational range
