GKs,

   Yet another M15 question.

Please check my math. I'll be really embarrassed if I screwed up ohms law.

My selector magnets are in series and reading a total of about 200 ohms.

This means to get 60mA I need to apply 12V?

I thought loop supply voltage was way higher than that, like up near 100v

Am I confused? Wouldn't be the first time.
