TITAN’s USB-ISO-M is a robust, industrial-grade full speed USB isolator that provides high-voltage 3kV isolation to protect the host computer and expensive USB equipment that are connected to it. This industrial USB isolator 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 isolator is very efficient and secured to eliminate ground loop currents and protect against overvoltage.

The data transfer rate of USB-ISO-M can be configured to either USB2.0 full speed 12Mbps or USB1.1 low speed 1.5Mbps. The isolator is bus-powered and provides up to 420mA current to downstream devices. There is no need for any driver or software installation. By plugging the cable from the USB isolator to the host USB port of the PC and connecting your USB device to the downstream port of the isolator, the host PC and USB device are immediately protected by isolation.

The USB isolator helps improve system stability and protect valuable industrial and medical equipment. When the USB host and USB devices are operating at different ground voltages, the USB-ISO-M is an ideal protector to prevent damage.
