DT5 Free Range Type Thermocouple Converter
Brand: Yokogawa Electric Corporation
The DT5 is DCS correspondence nest stored type signal conditioner that is connected to an IEC/JIS-standard thermocouple (TC), such as a Type K, T, E, J, R, S, B or N thermocouples to convert temperature signals into isolated DC current or DC voltage signals.
Features- Selection of input type, input range setting, burnout setting, output adjustment, I/O monitoring, and loop back test can be made using the communication I/F card (DSC2) and 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-600).
