Send/receive loop circuit composed of XTR112 and RCV420

As shown in the figure, the RTD uses a Pt100 thermocouple. When the temperature is 100-600oC, the output current of XTR112 is 4-20mA, and the output voltage of RCV420 is 0-5V. The figure shows a two-wire RTD connection. If a remote RTD is required, it is recommended to use a three-wire RTD connection, changing RG to 1180Ω and RLIN2 to 40.2kΩ.
