4-Channel Industrial 4–20 mA Interface – USB-C PCB Design

4-Channel Industrial 4–20 mA Interface – USB-C PCB Design Custom-designed four-channel analog interface PCB developed for industrial 4–20 mA signal acquisition and monitoring applications. The design combines industrial analog current-loop inputs with electronic signal conditioning and a USB-C interface for connection to external equipment. Key design features: Four independent 4–20 mA analog input channels Analog signal conditioning circuitry Input signal conversion for electronic measurement USB-C interface Compact PCB layout Component selection with consideration for industrial applications Design considerations for manufacturability Engineering work: Electronic schematic design Analog circuit development Component selection and integration PCB layout and routing Signal conditioning circuit design 3D PCB visualization Manufacturing documentation preparation Design software: KiCad The portfolio images demonstrate the schematic design, PCB layout, and 3D visualization of the interface. This project highlights my experience in industrial measurement electronics, analog signal processing, and custom PCB development for sensor and monitoring applications.
