PLC – PowerServo Isolation

I want to add TVS or Photo couplers to the PowerServoe and looking at the PCB lanes above you can see it is only five lanes crossing from left to right and I have plenty of space. All the caps are leftovers from PWM3 and can be partly removed if needed. This one is easy to make fully isolated. The only problem is that the opto couplers require some space and these boards are small… lets see what we can do.
