Advantech UHR402 2-Port USB 2.0 Isolator Hub

Add electrical separation to a USB peripheral path while retaining hub connectivity. The Advantech BB-UHR402 combines a USB-to-USB hub with two USB 2.0 ports and a 4 kV isolation barrier. It gives a host system a way to attach USB equipment where the connected side must remain electrically separated from the computer-side USB connection. USB isolation is relevant where equipment connected by cable can sit at a different ground potential or introduce electrical interference into a host connection. Position the isolator hub between the host system and the connected USB equipment to create an isolated USB path while keeping two peripheral connections available through one device. This arrangement suits control-system interfaces, industrial workstations, laboratory equipment connections, and other installations that need isolated USB communication. The UHR402 configuration is defined by its combination of two USB 2.0 ports and 4 kV isolation. That combination distinguishes it from a basic non-isolated USB hub, which expands port count but does not add an isolation barrier between the connected equipment and host side. Select this unit where both two-port hub connectivity and electrical isolation are requirements of the USB path.
