Safety Instructions 2. Safety Instructions Intended Use The USB isolators manufactured by Wiesemann & Theis galvanically isolate low-speed and full-speed USB connections with different isolation voltages. The insulators prevent compensating currents from flowing over the USB line due to potential differences between the connected devices, which can lead to data transmission disturbances or to the destruction of the interfaces. -
Page 7: Emc
Safety Instructions Only shielded cables may be used for connecting the Isolators. In this case the Isolators meet the noise immunity limits for industrial applications and the stricter emissions limits for households and small businesses. Therefore there are no EMC- related limitations with respect to the usability of the devices in such environments. -
Page 8: Introduction
Introduction 3. Introduction USB interfaces in stationary computers unfortunately have the basic drawback of having no galvanic isolation for the signal lines. In many applications in the consumer world this limitation is irre- levant, since the USB devices connected to the PC are generally supplied through the bus and do not have any reference to a second ground or to the ground conductor. -

#33001 4. USB Isolator, 1kV, #33001 Function The Wiesemann & Theis USB-Isolator #33001 provides galvanic isolation for low-speed and full-speed USB connections with an isolation voltage of at least 1000V DC. The Isolator eliminates ground loops and prevents current from flowing between the connected devices and the supply lines of the USB caused by potential differences. -
Page 10: Display Elements
Power Out LED indicates the voltage of the downstream side. Speed switching The USB-Isolator #33001 supports USB devices operating in full- speed mode at 12 MBit/s or low-speed mode at 1,5 MBit/s. Two small switches on the side of the Isolator labeled „Low Speed“ and „Full Speed“... -
Page 11: Wiring Example
#33001 Note A speed conversion is not possible by the Isolator, so that both switches must always be in the same position. A different setting for both ports will prevent data transmission. The factory default setting for the Isolator is Full Speed mode. -

#33204 5. USB Isolator Industry, 4kV, #33204 Function The Wiesemann & Theis USB-Isolator Industry #33204 galvanically isolates low-speed and full-speed USB connections with an isolation voltage of at least 4000V DC. The Isolator thereby prevents unwanted current which could otherwise flow between the connected devices over the data and supply lines of the USB. -
Page 14: Isolator Output Voltage
#33204 Isolator output voltage The output voltage VBus from the W&T USB-Isolator 33204 is brought to the galvanically isolated side of the module through a multi-stage L-C filter. These additional components significantly reduce the noise generated by the integrated DC-DC converter on the supply voltage of the secondary-side USB. -
Page 15: Speed Configuration
#33204 Speed configuration The USB-Isolator #33204 supports USB devices that operate in full speed mode at 12 MBit/s or low speed at 1.5 MBit/s. Switching between both speed is accomplished by means of two plug-in jumpers located inside the Isolator. One jumper each configures the upstream and downstream side of the Isolator. -
Page 16: Wiring Example
#33204 Since low speed devices are uncommon, the USB Isolator model 33204 is factory set to full speed mode. NOTE A speed conversion is not possible by the Isolator, so that both jumpers must always be in the same position. A different setting for both ports will prevent data transmission. -
