Hi...
I'm building an electronic project that has to control 4 relays.
I've one input sensor that could be 0-5V, 0-10V or 4-20mA selected with jumpers. My input microcontroller only accept 5V. What i have to do to the others inputs to have accurate results? If i use a voltage divider to the input 0-10V i´ll have unprecision results due to error associated to resistances. In my input 4-20mA how i turn in an accurate signal 0-5V?
There are any IC that does that?
Regards
