PLC – Power Key

I decided to go with a Power Key, meaning the motherboard will provide 24V, 12V and 6-8V on 3 separate pins. The module then decide what power it need by pin usage as illustrated below. The top image is my Power Servo Controller, while the lower one is PWM3. If a module need to select between 12 and 24V it can provide it’s own jumpers. The objective here is plug & play with minimal options to making errors.
