Spindle Relay Question

Hello again!

I'm looking at relays for my computer to control my spindle. Its a
brushless (PM) DC Motor. The drive will output at most 130VDC and 10A.
Newark has some made by Magnecraft that are solid state, rated for
200VDC and somewhere around 20A (forgot now exactly what they were),
with a 5 volt control voltage and they are already opto-isolated.
Perfect!

These are only SPST though. I need the computer to control the spindle
in both directions, and can't seem to find any that are DPDT. Does a
DPDT DC relay with that rating exist, or do I need a different circuit
altogether? I tried Mouser, Digi-Key and McMaster as well.

Thanks
David
