Hi all.
I'm currently figuring out my electronics setup. I have a pc power supply (separate from my pc) which gives me a 5v 2.5Amps standby,5v @ 14Amps, 12v @ 25Amps and 3.3v @ 14 Amps. My idea is to have the kflop/kanalog board powered by the standby 5v. so I have a mains switch that I manually switch to begin with, which then puts the psu into standby powering the Kflop/kanalog, then the Watchdog FET switches the psu on by grounding the green cable(see link below), the psu then outputs it's full 5v and 12v lines which activate a relay powering on the mains AC to all motor psu's and drives.
Does this sound about right? The green cable I measured to be outputting 3.3v, is that okay to wire diretly to the watchdog FET or do I need a resistor to keep the Amps under 1amp? Im not sure what amps that green "On" cable is outputting.

This is the psu: https://www.ple.com.au/Products/6286...U-Power-Supply
This is the mains relay: https://www.jaycar.com.au/solid-stat...ching/p/SY4084
Also, could anyone confirm that this same relay would be fine running a 1/2 hp coolant pump, though it would be a separate relay to the mains power one.
Thank you.
