USB ports for stationary computers have, unfortunately, the fundamental disadvantage to have no electrical isolation of signal lines.
In many applications in the consumer world, this restriction is not relevant because the PC connected to the USB devices are generally supplied through the bus and not through additional connections related to a second mass or to the protective earth have.
In the areas of data acquisition, control engineering or medical technology is such a galvanic decoupling of the connected devices, however, essential to prevent mutual interference from transients using the USB cable.
To this end, W & T to a family of USB isolators, which differ in the mechanical design as well as power supply and level of isolation voltage.
- Galvanically isolated connection between two devices with USB ports
- Isolation voltage min. 4000 volts DC
- Power supply insulator and terminal via the USB
- Optional external power supply on the upstream side
This option allows the connection of power-hungry USB devices
with a load current up to 1A without affecting the insulation voltage
- Supports Low Speed and Full Speed USB devices
- No installation of additional software drivers required
- Housing suitable for mounting on DIN rails
- Conforms to standardsboth in office and industrial environments:
- Increased noise immunity for industrial areas
- Stricter noise emission for residential and commercial areas

Send messages - when limits are violated or timer-based - for informational purposes directly to the responsible technical as an e-mail or as a reroute via SMS.
After the device has been configured for and connected to your network, the following steps are still necessary.
|Open the profile for configuring e-mail alarm messages.|
|Enter the desired parameters.|
|When the limit you have set is exceeded, the device sends an e-mail which can also be transmitted as an SMS message using special functions available from cellular phone service providers.|
