The PLC Backbone allows up to x PLC modules to assembled with PSU and communication in the backbone bus. This prototype allows 8 boards – thought 4 boards are more realistic due to space needed.
The boards can easily be interconnected using the dual 10Mbps RS-X links to scale up to a larger or distributed solution.
The bus have separate 5V,12V24V and 5V MCU Power. Jumpers at right are RS-485 Bias and Terminator. The design speed of RS-X is 10Mbps which should work on short distances like this.
