MU5 Free Range Universal Temperature Converter
Brand: Yokogawa Electric Corporation
The MU5 is a plug-in type universal temperature converter that converts input signal (thermocouple, RTD or mV signal) into isolated DC current or DC voltage signals.
Features- Selection of input type(thermocouple, RTD or mV signal), I/O range setting, burnout setting, output adjustment, I/O monitoring, and loop back test can be made using the optional Parameter Setting Tool (VJ77) or Handy Terminal (JHT200).
- The operation indicating lamp shows the operation status, abnormalities in a setting etc.
- Output adjustment, wiring resistance correction, and ON/OFF of RJC can be made using the switches on the front panel of the MU5 without a setting tool such as Handy Terminal.
- For the Fahrenheit display, specify the option “/DF”.
