The relay is more than capable of operating anything that has a 12 volt trigger on it.
Output of a relay depends on the input to the relay as well as the rating of the relay. A relay is just a switch but instead of a little handle to operate it, voltage is applied to a coil.
HERE is a link to the spec sheet for the relay I found in my
EARLY MSC400, they may have changed the relays, but I'm sure they are still quite adequate.
** NOTE ** I DO NOT KNOW THE OFFICIAL RATING, this relay is more than adequate but the tracings on the board are probably not up to the same rating
