  • RS232 <> RS422 interface, 50kV-isolated

Lightning protection for copper wiring


General information:

  • Isolated connection for RS232 and RS422 devices
  • 50kV isolation
  • integrated into the cable
  • No re-configuration of transmission parameters required
  • No separate power supply necessary
  • Protection against damage by lightning

Background information:

There is no protection against damage from lightning that hits your wiring system, due to the extremely high energy of the bolts. However, it is useful to protect your IT installation against damage from lightning that impacts on lines far away from your premises by using electrical isolators. An isolation of only 1kV already reliably protects you against most lightning damage. With an electrical strength of 50kV, the chance for such damage is practically nil. The experience of the last few years shows that customers, who had considerable damage done to their IT devices by lightning reported no such incidents since they had installed isolators.
