Applications

  • The 0...5 AAC RMS range makes it possible to accurately measure a typical current transformer.
  • The 0...300 VAC RMS range allows accurate supply voltage monitoring.
  • The 4179 measures standard input ranges, and can be freely configured to customer-defined input range.
  • Converts narrow AC current / voltage inputs to wide bipolar or unipolar outputs, e.g. 0...1 VAMS input = ±10 volt or 4...20 mA output with a minimum span of 0.5 AAC RMS or 0.5 VAC RMS.
  • The detachable 45xx displays provide enhanced diagnostics.
  • Configurable input limits control the output value for increased safety.
  • The 4179 has been designed according to strict safety requirements and is therefore suitable for application in SIL 2 installations.
  • Suitable for the use in systems up to Performance Level “d” according to ISO-13849.
