Re: 24 volt solenoid

So, I was about to post this question to Q&A, and I just wanted to do a quick CD pulse on this first.

R50 e. reads as follows:

"Electric solenoids may alternatively be supplied by a Solenoid Breakout Board connected to the NI 9472 cRIO module, which is powered by 12V."

Reading this alone implies that the Solenoid Breakout Board is to only be powered by 12V. This contradicts R42A which reads as follows:

"The cRIO power input must be connected to the 24 Vdc supply terminals on the PD Board. With the exception of one Solenoid Breakout Board, no other electrical load can be connected to these terminals."

Again, I know may be semantics, but, in my opinion, a clear contradiction. Does anyone else feel R50 e. should be amended to read:

"Electric solenoids may alternatively be supplied by a Solenoid Breakout Board connected to the NI 9472 cRIO module, which is powered by 12V or 24V."
