Description

The Expert Opto Bridge 0404 is an overvoltage protection for the serial and USB interface. It provides maximum protection from interference and failures and from damage to the interface by electrically isolated data transmission.

The interface isolator provides overvoltage protection by galvanic isolation of signals and voltages from potential damage to the PC from devices with USB and serial interfaces. In doing so, the electrically isolated data transmission provides maximum protection against interference, failures and damage to the interface, ensuring trouble-free operation of the connected devices.

The Expert Opto Bridge 0404 provides protection against a wide range of environmental disturbances:

  • Overvoltages due to remote lightning strikes
  • Overvoltages due to static discharges
  • Ground shifts caused by various mains circuits
  • Interference voltages on ground lines caused by motors or similar loads
