Description
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.
