The Johnson Controls M9208-GGA-3 actuator Rotary PROPORTIONAL; 70LB-IN (8NM) Spring RETURN AC/DC 24V; 24Vac, 24Vdc, 0-10Vdc, 2-10Vdc, (0)4-20mA with 500 Ohm Resistor, Proportional, 70 lb-in Torque, 150 second Power On run time, 48″ Appliance Cable with Integral 3/8″ FMC Connector Spring Return Direct Coupled Actuator
The M9208-xxx-x Series Electric Spring Return Actuators provide control of dampers in Heating, Ventilating, and Air Conditioning (HVAC) systems. All actuators in this series provide 70 lb·in (8 N·m) rated torque. A mechanical spring return system provides rated torque with and without power applied to the actuator. The series includes the following control options:
- On/Off, 24 V, 120 VAC, 230 VAC power
- On/Off and Floating Point, 24 V power
- Proportional, 24 V power, for 0(2) to 10 VDC or 0(4) to 20 mA Control Signal
These actuators are configured for direct mounting and do not require a damper linkage. Actuators can be mounted directly to a damper shaft from 5/16 to 5/8 in. (8 to 16 mm) diameter with a universal clamp. For shafts up to 3/4 in. (19 mm) diameter use the accessory Large Shaft Coupler Kit M9208-600. An accessory crankarm and remote mounting kit are available for applications where the actuator cannot be direct-coupled to the damper shaft. Optional line voltage auxiliary switches indicate an end-stop position or perform switching functions within the selected rotation range.
