I want to choose a RTD input module which can receive 1km distance signal away from RTD. then I found the Schneider company's BMXART0814. In their product datasheet has a term called "max cable resistance, related to 3 wire RTD, this resistance value is 20 ohm. Does it mean I can choose the cable under 20ohm resistance?? If so, I can calculate the length of the cable whether could reach 1km.
