IO Warrior driving 12vdc relays?

I am going to be using this in my CarPC and was wondering if IO Warrior is capable of turning on/off regular 12vdc car relays? Ive read the specs
O-Warrior 40
• 32 I/O Pins, typ. 125Hz read rate
• IIC master function, 100kHz, throughput typ. 750 bytes/sec
• Controlling HD44780 compatible LCD
• Driving a up to 8x32 LED matrix
• Driving a 8x8 switch or button matrix
• DIL40 or SSOP48 package

and if it can run those relays, do the 32 I/O pins mean that I can run 32 relays off of that one board? Thanks for the help

Yes, this is possible. Though you can not drive the relays direct, the IO-Warrior can not tolarate 12V and not supply enough current. You will need some driver that fits the specs of the relays.

i dont understand what you mean by "some driver that fits the specs of the relays" could you elaborate please?

The data sheet has an example for driving relays.
