I was looking at pictures of someone else’s enclosure (a camera company).  They 
have a router powered through a NO solid state relay and they’re keeping the 
coil circuit energized continuously.  The specs on the relay say the control 
voltage is 10-30VDC, but these folks have a 48V power supply.

I’m not sure how long it’s been in service (finding out today), but I’m 
wondering if this is a time bomb.  Is that relay going to fail?  What’s the 
likely mode of failure?  One article I saw while googling suggested the relay 
might get stuck on….not the worst thing, but it would defeat the purpose if 
that’s what happens.
