Hello everyone,

I would like to hear some comments on PCB relay (24 V) failure modes: i.e.
is it more likely that the contacts at some stage burn (when opening under
load), or does it happen more often that the coil gets it?

My gut feel was that the contacts should tend to go more often, but speaking
to the techies who normally service the units we manufacture once they're in
the field (I'm redesigning) it sounds like the coils might burn more often,
although no proper (quantitative) data is available on failures - many were
possibly misdiagnosed anyway...

Thanks
 Roland
