I put all the relays that would fit on the board.
So far, that's all that seems to be wrong.
It's our FITS cable fault insertion module, for our P940 modular power system.
Certainly we considered that. Several people make the big black ones and the small white ones and the SSRs. All are industry standards.
Some don't wash well in production, but there are workarounds for that.
The poyfuses and some software protections are there to protect the relay contacts and current shunts and stuff. We specify max voltages and currents, but you never know if a customer will respect that.
We drop the coil voltages from 12 to 8 when we're not transitioning, to keep the relays a bit cooler. There is guaranteed air flow too.
We spell it "relays" here in the developed world.
The Efinix FPGA is cheap, about $10, so we could buy a zillion if it goes EOL.
As one might imagine, the PCB layout was tough on that one.
Is there anything else you think we did wrong?

You mean English-speaking. Jan lives in the Netherlands, which is probably more "developed world" than the US. At least it has got universal health care. Jan isn't a great advertisement for the Dutch universal education system - most speakers of Dutch can spell English better than he can, but you aren't a great advertisement for the US education system either
