What do you think?

I would mount your mesa boards on DIN rail (7i96, THCAD-10, THCAD-5 shown). Mesa make a bracket but I suspect eusurplus make their own. The THCADs are mounted on a DIN rail mount I fabricated with some standoffs.



Mesa's best kept secret is the little strip of bus bar shown here to the right of the 7i96. 2 banks x 12 common connectors but eusurplus might not stock them. Saves a lot of space. 1 bank for+24v and 1 bank for -24v field power. Failing that a good supply of din rail mount connectors and common strips to tie banks of connectors together similar to whats shown.

Also the RS components 888-6843 relay is a nice compact (6mm wide) din rail opto isolated relay. You have to buy in packs of 5. I use them instead of the panel relays now. I'll let you find the right web site for your country but here is Australia

Pliers, isolating tape, and lots and lots of coffee !
That looks OK so far.
And do try to find the machine schematics, that will save you a lot of time, like a lot. Schematics are in a big book weighing at over 5KG, so if you do find it, do not drop it on your feet, you'll be limping for a week !

Not sure we have that book. I sent an email to esab germany asking for help. Let's see how they teat me.

Nice and clean setup.
I will get the din rail and ask eusurplus about the bus bar.
I'm getting those RS relays too.
I understand I need 4 of them.
Will be adding them to the list

Do the Mesa cards and THCAD come with din rail support brackets?

Or make one:
