Solenoid Controller
Solenoid Controller

This product was developed for a gas and oil drilling company. The circuit controls a latching solenoid which bleeds off accumulated water when the water float switch reaches a predetermined height. The solenoid open-to-close duration is adjustable between 1 and 20 seconds using a potentiometer.


This circuit contains a DC/DC converter, H-Bridge, and microprocessor. The circuitry was designed to have extremely low power consumption and will last for more than three years when powered from a standard 6V alkaline lantern battery.
