Basic AC/DC Din Rail Question

[tooki]

P.S. Here's a small rack-mount control cabinet I finished recently,

Hi Tooki
Not to criticize just to advance the professionality of your work.
Add cable ducts, they are not that expensive, place them horizontally above and under each Din rail and vertically on the sides.
Try to avoid combining mains and low voltage next to eachother butbyou know the EMC guidelines.
Cover it up and it looks way better. You do have the room for it.

I have actually already purchased ducts for my next project. I didn't have the little ones needed for this one. (The connectors and switches on the panels are too low to use the larger ducts I had around, and it would have been tight otherwise.) All AC and DC wires are in separate bundles here, with the only place where they run in parallel (but separated by about 2cm) is the 24V DC output of the power supply, making its way to the right as the yellow-black pair.

Actually, come to think of it, AC/DC separation is where I left off on the planning of the next project’s cabinet layout. I don’t want to combine them in the same ducts, and when I paused that project to finish up the one in the photo, I was trying to figure out an elegant way to run separate ducts, including how to manage crossovers.

Thank you - all good advice.

I’m opting for the Wagos in a din rail carrier. Seems neat and simple.

I have had second thoughts about the power source, not liking the idea of live AC having a remote chance of being an issue, so going with a AC to DC brick, cut the connector off, then it’s DC everywhere.  I will tin the leads.

I do have it in an enclosure but @Kjelt got me thinking if someone was to poke around when I’m not here……not worth thinking about.

Such a helpful community and I’m definitely going to stick around.

Oh yeah, I meant to mention: all the big DIN rail terminal block companies have web-based CAD tools for configuring entire DIN rails. You drop terminal blocks (and other devices) onto rails, add jumpers, end caps, and other accessories, and in the end you have a BOM of all the stuff you need, and it's guaranteed to fit together. (Some of them even let you order the rail preassembled -- they take your project and build it for you, including labeling.) Anyhow, these configurators are another way to dip your toes into DIN rails without actually needing to buy any hardware. The only downside is that you don't see the wires you're actually going to be connecting to them!

That’s really cool. I will take a look.

There’s even a “baby” tool like that just for configuring the PTFIX blocks!
