Look at the damn pictures of the relays, you can see the ratings and the
model number used.

And no, the relais themselves being specced for 220V doesn't mean shite when
the board its on has its low- and high-voltage tracks too close together.

The high-voltage tracks are MUCH fatter than the low voltage tracks on
the PCB, as you can clearly see in the photo of the underside of the
board, and high and low voltage sections of the board are well separated.
My main concern would be the high voltage tracks heating up and
deliminating when the current gets really high, but I think they are OK
for 10A.  Looks pretty good to me.
