Hello to everyone.
I would like to see your vision of following situation.
I have one board on my site which is designed not correctly in my opinion.So step by step:
1 when we feeding this board without another master board which is controlling it, outputs are directly connected to cable through relay, because I2C interface IC got all HIGH after start up (when master board is presented it sent control sentence and disconnecting this board from cables). My opinion is that is totally wrong in base design of this board
2 second mistake is that outputs are connecting to cable without any de coupling (optocouple or trafo) even when it working normally. Could it be that if this board is working in pulse mode we don't need to use deecoupling?
