DELTA DVP PLC Analog Read 4-20mA and
Display Pt00 Sensor Temperature from 4-20 mA ISPSoft
-----------------------
4-20mA Analog input Calibration
-------------------------------
All are Proportional Data
Step1= 4-20, 0-100c
Step2= 0-100 = 4-20mA
0C = 4mA
100 = 20mA
Step3= Current Span 20-4 = 16mA
Step4= 20mA = Digital RAW data = 1000max
Step5= 20 ma = 1000max
1 ma = 1000/20
4 ma = 1000x4/20 = 200
1000-200 = 800
200 = 0C = 4mA
1000 = 100C = 20mA
Step6= Digital RAW Data Span = 1000-200 = 800
Tempera per Digital RAW Val = 100/800 = 0.13, unit temperature
Digital RAW Val per Temperature = 800/100 = 8, Digital Unit
Step7= Calculation1 =Actual Temperature= Digital RAW input or Source Val x 0.13
Calculation2 = Actual Temperature = Digital RAW input or Source Val/8
