Hello Mates, I do not have the intention to criticize this company work, just want to know your thoughts about this construction pros and cons |
| Gregg:
It is very neat and tidy. Maybe you can post a copy of a block diagram or schematic so we can see why it needs to be so complicated. I have only worked on old school relay logic fire pump controls which were very robust and quite easy to troubleshoot. Then there is trusting lives to an Arduino questions. |

Attached is the schematics, its in portuguese but, google can help https://drive.google.com/drive/folders/1OXi2Jw7xf9LyVUrQ9oulzOOlMF8eJ4fP?usp=sharing |

Well, it might be perfectly legal, but I do not like the practice of mounting naked PCBs in switchgear cabinets like this one. A certain form of build will cause the people to treat it in the same way. Like opening the cabinet and turning around with a extension cord swinging -BOP!- onto the PCB. :-\ |
