I am familiar with designing and creating AC controls. But when it comes to DC, it is something I have not been involved with very much.
Let's suppose I have a control circuit that uses 120vac for power and consists of a directional control valve that operates a hydraulic cylinder and has limit switches and/or proximity switches and time delay relays. Now suppose I want to take it and set up something similar in a 12vdc circuit. Other than making sure all my coils are 12vdc coils and my swithc ratings are correct, are there any fundamentals that need to be observed and followed with a DC circuit that is different from an AC circuit?
The reason behind my question is because I want to set up a control on a portable, engine driven cart using it's 12vdc electrical system for my power source. It will need to operate some control valves to control hydraulic cylinders etc. I want to make sure I get things started off on the right foot.
Thanks in advance for your response?\!
