DR5 Free Range Type RTD Converter
Brand: Yokogawa Electric Corporation
The DR5 is DCS correspondence nest stored type signal conditioner that is connected to an IEC/JIS standard resistance temperature detector (RTD) to convert temperature signals into isolated DC current or DC voltage signals.
Features- Selection of input type, input range setting, burnout setting, output adjustment, Input/Output monitoring, and loop back test can be made using the optional Parameter Setting Tool (VJ77) or Handy Terminal (JHT200)
- For the Fahrenheit display, specify the option “/DF”
- Available for the combination with Safety barrier (BARD-700)
