PLC Backbone Bus

If I use a 10cm wide backbone I have room for a 2×30 (or 3×30) by 2.54 pitch “bus” that could contain the following Inventory:

Summarised this gives me:

  • 4 pin 5V PSU (5-10A)
  • 4 pin 12V PSU (5-10A)
  • 4 pin 24V PSU (5-10A)
  • 4 pin 48V PSU (5-10A)
  • 4 pin GND 5V
  • 4 pin GND 12,24,48
  • 8 pin data bus
  • 12 address bus
  • 10 function/extra address pins
  • 8 pin for 4 RS-X lines (RS485)
  • 2 clock pins

This is just a working draft…
