Yep... but if you had any 12V coils being powered by 24V, you were severely overpowering them. It could be that you never had them on long enough to release the smoke.

Can someone please clarify the 24V power out pins on the PD? A close reading of all the Robot rules as well as the manuals for the PD and the Solenoid breakout* did not reveal their meaning to me:

The 24V output pins are labeled: V - C - NC - C
It is labeled V - C - NC - C, but it is actually wired V - C - V - C, meaning +24V - GROUND - +24V - GROUND.

Sorry for the confusion. The history here is that the cRIO is wired as it is labeled, and we reused the connector. I thought we might need the extra 24V tap, so I wired up the NC pin.
