Hello All,
What I'm trying to do:
Monitor (data log) a 0-24 volts control signal from a piece of industrial equipment.
Problem: my data logger only reads 0-2.5 volts
Solution?- Build a voltage divider circuit to step down the 0-24 volts to 0-2.5 volts. I read the sections on DC voltmeters and effects on the circuits being monitored.
Question: How do I make sure my voltage divider circuit dose not effect the control circuit I'm monitoring?
Just use resistors in the Mega-ohm range? Is there a way to know how big the voltage divider resistors should be?
Thanks,
