For applications that require embedded USB isolation, the SeaISO™ ISO-1-OEM is the ideal solution. The OEM single-port, inline USB isolator offers a simple method of protecting host and field equipment from damaging transients and surges commonly found in commercial, industrial and medical environments. The ISO-1-OEM is UL Recognized, in accordance with EN60601-1 3rd Edition, and protects both the data and power lines with 4 kV of medical-grade isolation between the host control system and connected USB equipment.

The ISO-1-OEM is USB bus powered and the efficient DC/DC design allows energy transfer over the isolation barrier. The isolator provides up to 300 mA to a downstream USB device when connected to a standard 500 mA USB port. Additionally, the isolator can provide a full 500 mA to a downstream device when connected to a USB port capable of sourcing 1 A, or greater. Convenient high-retention USB connectors prevent accidental cable disconnections.

Supported in Microsoft Windows, Linux, and other USB aware operating systems, the ISO-1-OEM requires no separate drivers. The isolator is easy to install and is automatically recognized as a generic USB hub device. The ISO-1-OEM is a USB 2.0 compatible device connecting to the host over a high-speed link and features full-speed (12 Mbps) data rates between the downstream USB device.

The printed circuit board includes M2 x 4mm threaded standoffs to simplify mounting in your application. Standard operating temperature range is -20C to +60C and extended temperature ranges are optional. A variety of USB cables are available as accessories. If you need a USB isolator with removable cables, see the ISO-1. If you need a ruggedized USB isolator cable, see the ISO-1R.
