TITAN’s HUB-400i-ISO is a robust, industrial-grade 4-port full speed isolated USB2.0 hub. HUB-400i-ISO expands one USB port into four optically isolated USB ports with high-voltage 3kV isolation both upstream and downstream to protect the host computer and expensive USB equipment that are connected to it. This industrial USB isolated hub is designed to build protective isolation barriers to the power and USB signals between a host computer and any connected USB devices. Both the computer and the connected USB device are protected from harmful voltage, power surges, transient voltage spikes, ESD shock, EMI/RFI interferences and noise that may cause damage and inaccurate measurements. The isolated hub is very efficient and secured to eliminate ground loop currents and protect against overvoltage.
