PLC I/O Build

I’ll be taking PLC programming classes soon as I complete a degree in Industrial Electronics, so in preparation I decided to set up a PLC for tinkering at home. I chose a Siemens S7-1200 with TIA Portal as the automation software. Everything is mounted on din rails with pegboard brackets that I 3d printed.

Then I just needed to build the Input/Output trainer. I ordered all the parts from China via Aliexpress to save money. Everything went together smoothly, and it gave me an opportunity to use my new Knipex Ferrule Crimpers (they rock). The trainer has 4 Inputs (pushbuttons and switches) and 4 outputs (LEDs and an alarm). I also added a 24v fan to a rail as an additional output.
