MVP 2021 kratmel Posted August 31, 2019 MVP 2021 Report Share Posted August 31, 2019 It is impossible for SM35 J R20. You need to use SM35 J RA22 or SM35 J TA22. Quote Link to comment Share on other sites More sharing options...
MVP 2021 Joe Tauser Posted September 1, 2019 MVP 2021 Report Share Posted September 1, 2019 As kratmel points out, the R20 doesn't have RTD inputs. The easiest thing to do would be to get an RTD / 4-20 mA converter and connect it to one of the R20's analog inputs. Google up "RTD transmitter". Joe T.
