Belimo DRCX120-3 NS/R Actuator On/Off/Floating 120V

The Belimo DRCX120-3 is a 120-volt, non-spring return (NSR) rotary actuator designed for precise airflow control in Heating, Ventilation, and Air Conditioning (HVAC) systems. The DRCX120-3 provides versatility in a range of applications by maintaining its previous position in the absence of power, in contrast to spring return actuators that immediately return to a fixed position when unpowered.  When in "on" mode, it fully opens the associated damper or valve to permit unhindered airflow. Airflow is stopped when the damper or valve is fully closed in "off" state. By using a control signal from a thermostat, building automation system, or other compatible device, the actuator in the "floating" mode can modify the position of the damper or valve to maintain the ideal temperature and ventilation throughout the structure.
