5vdc source
« on: August 24, 2009, 10:32:21 AM »
I know this has probably been brought up before, but do I use a 5 vdc source from my PC power supply to activate things like relays, pulse +/-, enable +/- , dir +/- , limit switches, etc, or do I need to use a separate power supply for this? I have 1 on order just in case. Will there be a conflict with the + or ground with the PC ? I'm ready to wire, but I don't want to burn anything up. :-[.

Any help with this would be greatly appreciated as the deadline on this project is drawing nearer.

Best to use a separate supply, and just tie the grounds together.

I normally use the 5 and 12 V from the PC power supply. If you take all needed care it should not be any problems, and sometimes it is very handy.
But separated power is always better.
