I want use this board and PiFace Relay+ to drive a 12 V DC motor, is that possible ?

If all you need is ON/OFF then any PI compatable relay board will work and you can often have uptp 24V and 5A (PiFace Digital for instance)
If you need to vary the speed then you need to be able to PWM the supply to the motor or use the PiFace Motor but this also requires the new PiFace Digital card, this is not a bad solution if you want to play with other things. This new digital card has smaller relays on it, hense the limit of 1A rather than 5 on the regular / older card
there are many ways to get this job done as the folks above have already shown / explained
To simply answer your question. Yes it is possible and with this board
you will have on off control with the relay and this will handle the motor you mention
with this board
that plugs into the above board you get the H Bridge control
and this one
Gives you more relays instead
Choice depends on what you want to do with the motor... read all the above replies
