RS 485/422 Isolator / Repeater

  • The RS 485/422 Isolator / Repeater – ISO 485/422 is primarily intended to provide complete Isolation between communication devices, so that they are protected against any inadvertent damage due to electrical disturbances. The ISO 485/422 also provides necessary immunity to a System against Electrical Noise Interferences and differential ground.
  • The Product can also be used for extending the operational distance by acting as a Serial Repeater / Amplifier.
  • ISO 485/422 is available as a compact unit enclosed in a plastic casing, which takes power from the supplied Power adaptor.
  • The Converter is populated with Surface Mount components for good reliability and to reduce the size. At the same time, it is equipped with good and reliable Isolation to Data signals.
