Arne/Bob--
Well, I DID look very closely and since the operating voltage is
high-lighted in
YELLOW and only ONE of the ratings is high-lighted in yellow then I would
have to believe that the other columns are NOT voltage and that each
of the two
ROWS correspond to each relay.
I am SURE you are right, but the Specifications Table leaves a lot to be
desired. If, in fact, the three gray columns at the top are actual
voltage ratings
then they ALL should be in yellow!
Reminds me of a poorly designed rental car we had in Alaska last
month. I believe
it was a GM product. There is ONE slide switch for both Trunk UNLOCK
and Door LOCK.
But the nomenclature above the switch is not clear. The Trunk UNLOCK requires
a slide and HOLD for some interval. But if you don't wait the
interval then nothing
happens. So if you then try the other position it looks the doors. Better not
slam the door shut in frustration at that point -- especially if you
have the keys
inside!
I will repeat my comment -- "that the Gigavac relays APPEAR to be
rated for much less
RF current" -- precisely because the entire row is not high-lighted in YELLOW.
Of course it makes SENSE that the three relays have comparable
ratings -- but that
is not the way the table appears with only ONE box in yellow!
So we are all correct! ;-) John W0UN
