The Universal Serial Bus (USB) increasingly finds use in industrial applications, where it can support software upload and configuration, assist with diagnostics and maintenance, and connect peripheral devices. However, USB was defined as a consumer-electronics interface, and it doesn’t inherently tolerate the noise disturbances, ground bounce, and ground potential differences found in industrial environments.
To overcome such limitations and meet the needs of a broad spectrum of factory-automation, medical-equipment, and power-delivery applications, you can implement a galvanically isolated USB interface. However, you will need to ensure that your interface complies with EMI standards and minimizes inter-symbol interference (ISI).
