1 General Specifications GS J0U0-0E Model MU Universal Temperature Converter (Free Range Type) General The MU 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. 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 (VJ) or Handy Terminal (JHT00). The operation indicating lamp shows the operation status, abnormalities in a setting etc. adjustment, wiring resistance correction, and ON/OFF of RJC can be made using the switches on the front panel of the MU without a setting tool such as Handy Terminal. For the Fahrenheit display, specify the option /DF.
