This document provides a diagram and description of the wiring for an OleumTech base unit application. The diagram shows a solar panel, battery, pressure transducer, arrival sensor, interposing relay coil, 250mA fuse, and valve solenoid coil connected to a base unit that converts a 0-50 VDC signal from the pressure transducer to a 1-5 VDC signal. The base unit provides power regulation and signal conversion for the application.
