solid state relays

I have four, 5A, 280V solid state relays. They are activated by 3-8V. I need to tie them together so that I end up with a total of 20A. Do I tie them in series, or parallel? Also, do I tie the inputs in series or parallel so that there is one input? Thanks.

Parallel-out, either in, depending upon your input supply.

120V AC power input, US mains. And the signal (not supply voltage) input can be series or parallel? that simplifies things. thanks.

Something like this should do if 12V will activate them.
