Introduction
The SeaISO USB Isolator is a device that provides galvanic separation between USB devices and host
control systems. It is powered from the host system and allows energy transfer over the isolation barrier
to the slave device. The Isolator is a USB 2.0 compatible device connecting with the host over a high-speed
link and featuring full speed (12 Mbit/s) connection to the isolated slave device.
Model ISO-1 is a standard version enclosed in an ABS plastic case dedicated mainly for industrial use.
Model ISO-1R is a custom ruggedized version featuring cable “bump” design and sealed TPE overmold for
environmental protection in medical applications.
