At this stage you move from programming Labview to interfacing to the
real world and you need to use some different skills for this.
What you have to do is add a relay for example to the SCB68 to
interface the logic line from the Input / Ouput card to allow switching
a high current device such as a motor, solenoid or light bulb.
There is heaps of material which covers how to interface to the real world here http://www.ni.com/events/tutorials/campus.htm
With some examples of what is required and what NI products can be used.
Often the actual hardware interface from the NI boards is determined by
the project requirements found in the real world. Correct selection of
the interface details comes from a combination of training and
'experience in the field' or seeing how others have handled the problem.
