1. Input/output circuit including opto-isolator 2. In each module use individual voltage regulator for Vdd. 3. I plan to use the PROTECT output for emergency stop cnc machine 4. One Layer PCB According to the datasheet SLA7078MPR has more functionality and easy connectivity with a minimum of external components.
