Johnson Controls M9208-BGA-3 Actuator

The Johnson Controls M9208-BGA-3 is a rugged Spring Return Direct Coupled Actuator engineered for precision control of dampers and valves in demanding HVAC environments. Providing 70 lb-in torque, this 8 Nm actuator operates on a 24Vac/Vdc power supply, delivering reliable two-position (on/off) functionality. Designed for longevity, it features a 55-71 second power-on run time and a mechanical spring return that ensures a fail-safe position during power loss in under 25 seconds. The unit comes equipped with a 48-inch appliance cable and an integral 3/8" FMC connector, simplifying field wiring for contractors. Its compact housing allows for mounting in tight mechanical spaces while maintaining high-torque performance for commercial HVAC damper control. This JCI M9208 series actuator is a direct replacement for various legacy units, offering the durability required for high-cycle applications without compromising on timing accuracy or fail-safe actuator reliability.

• Fail-Safe Reliability: Integral mechanical spring return ensures the damper or valve returns to a known position during power interruptions.
• High Torque Output: 70 lb-in (8 Nm) rating provides sufficient force for medium-sized dampers and zone control applications.
• Simplified Installation: The 48-inch cable with a 1/2-inch (3/8" FMC) conduit connector reduces setup time for field-mounted actuators.
• Versatile Powering: Compatible with both 24 VAC and 24 VDC circuits, providing flexibility for diverse control panels.
• NEMA 2 Protection: Constructed to withstand standard indoor mechanical room conditions and moderate moisture.

Common Questions

Can this actuator be used for modulating control?
No, the M9208-BGA-3 is specifically a two-position (on/off) model. For 0-10 VDC or 4-20 mA modulating requirements, you should specify the AGx or GGx series.

Is the rotation direction reversible?
Yes, the actuator is designed for easy reversal. By flipping the unit over, you change the spring return direction (Clockwise or Counterclockwise) to meet the specific requirements of the damper or valve assembly.

Does this unit include auxiliary switches?
This specific model (BGA) does not include internal auxiliary switches. If end-of-travel feedback is required for your sequence of operations, an auxiliary switch kit or a model with the "C" suffix should be utilized.
