Are you talking about scaling ? |

i scaled it like 0V = 0A, and 1V = 30A but i don't know if that will work or if i need to apply ohm law |

Sure, i'm using a s7-1200 DC/DC/DC and here's a print of my function right now. |

0-1V is very low resolution to play with i think. i had attached values for 0-10V |

ok but the sensor gives me values betwhen 0-1V do i need an external circuit to amplify the signal ? |

Hello Bacelo, you can use a signal conditioner to transducer 0..1 V to 0..10 V. e.g. Signal conditioner - MACX MCR-UI-UI-UP-NC - 2811297 from Phoenix Contact. This part can you configure with DIP-switches at the front, it's very easy. The precision of this signal conditioner is better than 0.1 %. Then you have a resolution of 30 A / 27648 = 1 mA regards |
