Serial Port Isolator


Serial Port Isolator

  • The RS 232 Serial Port Isolator – ISO 232 M is primarily intended to provide complete Isolation between expensive computer or system from the serial device, so that they are
    protected against any inadvertent damage due to electrical disturbances. The ISO 232 M also provides necessary immunity to a Computer or a System against Electrical Noise and
    differential ground.
  • ISO 232 M 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 and Protection to Serial Port from high voltage (2500 V)
