I have a need to be able to connect a lead on a circuit to 1 of 5 different other leads. I think it’s obvious how I can accomplish this with jumpers or DIP switches or encoders.
The wrinkle here is that the voltage is somewhat high ~ 30V.
My question is: is there a electrically controlled way to accomplish this? I’ve looked at multiplexers and some other options but once you get into the 30V range these components seem to get too expensive to justify the cost.
What options are available in this situation?
To summarize, a good solution would:
- Allow electronic control
- Handle ~ 30V @ .5A
- Be low cost — If one component handles mapping 1 to 5 lines, I’d need 5 of them on the board; each of 5 lines gets mapped to one of 5 lines.
