In answer to #2, the DAQ card's analog and digital outputs cannot drive
enough current to turn on a relay. What you need to do is use the output to
drive a MSOFET or transistor that will drive the relay. You can use the 5V
computer supply that is available on the DAQ card connector as the power
supply that the MOSFET or transistor use to turn the relay on.
