Now there is no shame in this. One of the controllers mentioned is worth a couple of grand. I do not want you to be responsible for messing things up if you make a mistake. We all do.

The best and safest solution is to get an electrician in, this is not electronics any capable electrician will be able to perform the wiring. Yes it may cost some currency, but is the wisest way to progress. I fear the actual wiring of the relay contacts to the various signal sources may prove to be overwhelming for yourself.

So it’s time to fess up, be honest and get some actual on site help. Sometimes that is just the way it is.

I honestly think this is the wrong project for you to begin on. Others may disagree and you are quite welcome to disregard my advice.

All in all I wish you the best of luck. Last of all if you do this yourself work slowly and check for correct operation as you go. It is easier to deal with one mistake at a time.
This a personal project (it is my fiber laser) and I will do this by myself. I will put some led's with the appropriate resistor (for load) and try the circuit before commit and install everything on the laser. Nothing on the last question...

Thank you for your advices so far.
