Key benefits Provides electrical isolation between the USB host and USB device to protect both sides from noise, ground loops, and interference. Improves reliability in noise sensitive and precision applications such as precision USB data acquisition and HiFi audio systems. Enhances debugging stability for equipment such as JTAG/SWD emulators, ISP/ASP/IAP downloaders across multiple USB interfaces. Safe for use in environments with strong electrical noise or interference, including voltage lines, inverters and motor drives, by isolating the computer side. Reduces crashes and damage risk for common industrial USB devices such as USB mice, keyboards, and USBtoserial adapters; can extend USB cables and act as a USB repeater while isolating ground potential differences. What it does Isolates the USB interface between host computer and connected device, preventing electrical noise and ground differences from affecting operation. Enables longer USB cable runs by functioning as a USB repeater while maintaining isolation for downstream devices. Protects both equipment and operators in harsh environments by keeping the computer isolated from noise or voltage areas. Supports a wide range of USB devices and interfaces common in debugging, data acquisition, audio, and industrial applications.
