Is there a correct schematic?

Any PNP transistor will do as long as you don't exceed its max rating. I
run 30v through the 3906 without problems.

Ok, I marked my schematic. Gee, why didn't I notice that ?
I did not see a voltage input range.
Likely 12 to 48 or maybe even up to 75 VDC ?
I plan to make of the these as
go low if conductivity is high.

Ken,
Would you send me a schematic of your current control circuit?

### Might be a good idea to differentiate between regulating and
limiting. They're not quite the same thing.

Is that a short across the input..?
