I hopefully have a quick and simple one.
I use a form A relay to switch battery voltage to a grounded resistive
load. Does it matter which contact is always hot and which one ties to
the load? I have been assigning the common contact to VBAT and the
N.O. contact to the load side. However, it would be much cleaner and
more convenient to swap the two contacts in a new board layout. Would
this pose any problems?
I'm running this device at 13.5VDC, 25A. The part is rated for 16V,
30A. Ambient temperature in my application will reach approximately
100C. I will do anything I can to prolong its life expectancy. One
would think swapping contacts would be a no-brainer. However, there
are always got-cha's.
Thanks,
George
