How would you create a larger voltage out than 10V from the NI9269

The NI9269 has an output of +/- 10V. My input that I required to power is 24Vdc. How would I go about this?

Sounds like you are going to need a voltage amplifier.  Do a search on Digikey and/or Newark and you should be able to find one that will work.  You will need to supply a power source for the amplifier though.

The 9269 has 4 isolated voltage sources.  You can connect them in series for up to +/-40V (+/-10mA limit).  This will be isolated, so if you're trying to get +24V relative to ground, you'll need to tie the lowest (-) terminal to ground.  To get +24V, you'll need to use 3 of them. If you don't need a variable voltage, this seems like an expensive way to generate 24V.  T The operating instructions have information on how to make the connections:  http://www.ni.com/pdf/manuals/375099b.pdf

that is a novel idea! never thought of that....let's hope he is using this as a signal source and not as a power source for hardware?
