I'm doing a PCB for something similar at the moment - it's away getting
etched. It's a distro board with a relay and an adjustable delay. There is
no need to have relays for each module. One per "bank" should be adequate.
Just add modules until you get problems, then remove one. Add that module to
the next bank. It's the inrush that's the issue. It's similar to an old hard
drive problem, where staring current is so high that a bank of them would
require a starting supply that can deliver twice what running requires, so
each drive is delayed for 10 seconds times its ID number. That way the
supply only needs supply the starting current for a single drive at any time.
