Universal Control panel build

Also, 5 volt deos not need to be an issue, Just use opto couplers or level shifter on one of your boards to add a 24 volt logic side.

Lol yeah I already said that

If I do another version of the BOB I could add some 12v, higher current outputs. Besides that some little 4 channel mosfet or opto board off Amazon could handle it

Ethercat for a control panel?
 

Yes, we did locate complete ethercat control panels. eg. Something like this
panelmategroup.en.made-in-china.com/prod...l-Panel-Codesys.html
 

That's big money. Sounds like you're saying you already have one of these working on your machine?

No, a couple of us working on  ethercat machines found it and wondered about using one. I had already built my HMI by then. Kinda similar to this with a H2+ and circuit board breakout inside but being ethercat, I did not attempt to use the  H2+ I/O.
I went the minimalist HMI route with a an estop and 3 buttons
QT_dragon does the rest.

Going the Ethercat route is not necessarilly cheap regardless of what you do..

Did a new version of the break out board for a Teensy 4.1, just waiting on a friend to add some I2C functionality to the Arduino-Connector code. I added a 8 high current outputs to this one, for something like a "semaphore", light tree... thing, or whatever else

 

Hinge / adjustable keyboard looks great to me. Might not be ideal for a workplace setting as exposed pinch points, but for personal use it's a simple and reliable functional design.

The 4x4 button panels -> are they individual buttons that you've put on a PCB yourself, or are they a ready made matrix?

Can you please share the source for the keyboard?
