Abstract
A well system with an electrical control and sensing system includes a first conductor and a second conductor. A first switching circuit is coupled between the first conductor and the second conductor. The first switching circuit includes a first electrically powered device and a first diode coupled to the first electrically powered device. A sensor circuit is coupled between the first conductor and the second conductor. The sensor circuit includes a sensor and a sensor diode coupled to the sensor and configured to permit current flow through the sensor circuit from the second conductor to the first conductor.
