Hi , I have a challenge , i need to measure voltage of car battery by using plc fx 2n mitsubish , with devices is needed and which ladder logic is use

Your challenge is one analogue I/p ...
which FX do you have mind - assuming you will have 0-10vDC and would measure range 0-15vDC from the battery. What accuracy do you think you can achieve by perhaps a voltage divider.

Apart from scaling this analogue, what you want to do with the measurement ?
