Actually, what I have done is a) use 24V across the switch, since then errors are less significant, b) use a current-controlled optocoupler to shift down to 3.3V logic levels and c) use a RC filter just as you described. Maybe you could add that to your answer to make it easier to find that info for others. Anyway, in my opinion this is close enough to what actually solved the problem to mark it as accepted answer. BTW: Seperate calbes are not available since that part of the machine was not designed by me and is a given :( | |
