The SeaISO™ ISO-1 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 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 is USB bus powered, eliminating the need for external power. 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 requires no separate drivers and is easy to install. Simply plug the isolator into an available USB port with the included cable, and it is automatically recognized as a generic USB hub device. The ISO-1 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 ISO-1 is housed in a rugged plastic enclosure with mounting ears that simplify mounting to walls, under counters, or inside panels. Standard operating temperature range is -20C to +60C and extended temperature ranges are optional. The USB isolator is shipped with a 1 meter USB A to B device cable and 1.3 meter USB extension cable. If you need a ruggedized USB isolator cable, see the ISO-1R. If you need an OEM USB isolator to integrate into your application, see the ISO-1-OEM.
