relays

Hi all,

I am putting together my second parallel breakout board and on the
first, I used small half amp relays, but was driving small loads,
solenoids and stuff.

I ran a motor starter so that was an off board device that only
needed a signal, so the 1/2 amp worked fine. Seems spindle starters
will always need a full line voltage contactor so can use low amps
for the coils, or use VSD's so again low amps.

I'm wondering if there is any great need for higher amp relays on
board?

it seems that I am faced with either using slightly larger 5 or 10
amp relays, using mini's and powering external relays ( when
required ), or just moving them off-board alltogether.

anybody burn out relays on board to make that a less favorable
method ?

Any recomendations on mini's vs. 5A/10A vs. off board ??
