I am not familiar with relay 9 and 10 operation. But I have found the 
Morningstar Relay Driver to be a good solid unit.

http://www.morningstarcorp.com/en/relay-driver

Free software on Morningstar's website. Requires 9 pin RS-232 port on 
PC. Can program voltage thresholds, generator starts, etc.

We used to use them extensively at remote sites. We've gone towards more 
specialized gear now, but that is not due to any shortcoming on the 
Relay Drivers part.

(incidentally and shameless plug, I have some used units available for 
$50 + shipping)

Good luck,
