PS_on switching a SSR
-
Hallo,
I use two normal Meanwell Power supply. One for 24V and one for 5V.
I made a quick conection plan but i am not sure if it works, could you please check it.
ziemlich groß -> pretty high value
Netzteil -> powersupplyis there a possiblity to switch the SSR direktly?
best regarts

Yes just connect the SSR control terminals between +5V and PS_ON.
-
notice:
you need a varistor over the SSR when its swichting an inductive Load.

What about mechanical relay like this one? https://www.amazon.com/gp/product/B00E0NTPP4/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1

Switching PSUs are not significantly inductive so do not require a varistor.
If you use a mechanical relay instead of an SSR, you must connect a flyback diode in parallel with the relay coil, otherwise you may damage the PS_ON output.

So this looks good to go then?
-
You can connect VCC of that relay module to +5V and IN1 to PS_ON.

Thanks! Thats what I thought. Should I gnd it to Duet WiFi also?

You will need to power the relay board from +5V (or 12V, or whatever voltage it needs) and ground too. I presume that's what J5 is for, although the schematic for that part doesn't make sense.
