±12V power supply transmission/receiving loop circuit composed of XTR105 and RCV420

As shown in the figure, the RTD uses a Pt100 thermocouple. When the temperature is 100-600oC, the output current of XTR105 is 4-20mA, and the output voltage of RCV420 is 0-5V. The figure shows a two-wire RTD connection. If used for remote RTD, it is recommended to use a three-wire RTDs connection, RG is 383Ω, and RLIN2 is 8060Ω.
