Application

  • 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.

Technical characteristic

  • The latest analog and digital techniques are used to obtain maximum accuracy and immunity to interference.
  • Possibility of output safety feedback by selecting S4...20 mA output.
  • The current output can drive up to 800 Ohms, with an adjustable response time of 0.0…60.0 seconds.
  • Exceptional mA output load stability of <0.001% of span / 100 Ohm.
  • Meets the NAMUR NE21 recommendations, ensuring high accuracy in harsh EMC environments.
  • Meets the NAMUR NE43 recommendations, allowing the control system to easily detect an input error.
  • Tested to a high 2.3 kVAC, 3-port galvanic isolation level.
  • Excellent signal to noise ratio of > 60 dB.

Mounting / installation / programming

  • Very low power consumption means units can be mounted side by side without an air gap – even at 60°C ambient temperature.
  • Configuration, monitoring, 2-point process calibration and more are accomplished using PR's 45xx detachable displays.
