Your caps lock is stuck ;) |

But to answer your question many possibilities, I use mainly: 1) voltage divider (two resistors) https://en.wikipedia.org/wiki/Voltage_divider 2) opto coupler The first one I use with local (on pcb) voltages that are referenced to the same ground. The second I use mainly with off pcb voltages from different devices. |

thank you for the valuable reply. Please suggest optocoupler circuit. |
