Isolated send receive ring circuit diagram XTR105 RCV420

  
As shown in FIG later, RTD temperature collected in the field, which was converted into a voltage by the XTR105 voltage is converted into 4 ~ 20mA current output, and then the
Isolated send receive ring circuit diagram XTR105 RCV420 - schematic

twisted pair transmission, received by RCV420, after isolation amplifier ISO122 isolation amplifier, output 0 ~ 5V voltage. Excellent anti-jamming performance of the circuit can be used for long-distance transmission interference or big occasions. The figure for the three-wire RTD connection, if used for two-wire RTD connection, remove RLIN2.
