Honeywell MN7220A2205 Non-Spring Return Proportional Damper Actuator W/2-Auxiliary Switches 2-10 VDC 4-20mA 24V

The Honeywell MN7220A2205 is a 24V proportional control actuator with two stages that is intended to precisely regulate the flow of gas or air in HVAC systems. It has a direct coupled motor with non-spring return (NSR) for quiet operation and 175 lb-in of torque for tough applications. The two-stage operation includes an on/off stage for system activation and deactivation with a proportional stage that uses a 2-10Vdc or 4-20mA signal for fine-tuned adjustments based on temperature or pressure changes. Two integrated auxiliary switches provide more control options. This adaptable actuator blends in perfectly with the current HVAC systems and works with a variety of Honeywell products, including the MN7000 series dampers. Gains include quieter operation, more accurate airflow control, and increased energy efficiency, which improve comfort and save money.
