6) Temperature conversion characteristics
The RTD input module, as shown below, linearlizes the non-linear characteristic resistance input of the RTD
7) Digital conversion value
The RTD input module, as shown below, outputs digital converted value of detected temperature value.(Range 0 ~ 4000)
Digital Conversion value = (Detected Temp. value+2000)/2
Example) Assume that Detected temperature value(D4980) is 2345, then real temperature = 234.5, and Digital
conversion value(D4770) is (2345+2000)/2 = 2172.
