Hi, I have connected pressure sensor of range 0-10 bar giving output of 4-20mA to the AI of the PLC of range 0-10V. With the help of 560 ohms i have converted the 4-20mA value into voltage. Now, to show the pressure in bar how should I configure the FC105 block. ------------------------------------------------------------------------------------------ |

I doubt the sensor works like that. 0-4ma is "wire break" not vacuum. 4-20ma is listed range of sensor. 1-10bar you said; but with 560 ohm resistor that is 1 - 8.9 bar. BTW: I use a precision resistor when doing this. https://www.mouser.com/ProductDetail/IRC-TT-Electronics/RC55-D-500R-B-B?qs=sGAEpiMZZMu61qfTUdNhGwOxGApD8HSVCo3sjC90JGI%3D |

Hi in some PLCs built-in AIs are voltage only so he needed a resistor to convert 4..20mA to 0..10V |
