Line Sensor Wiring to Solenoid Breakout(?)
 

I haven't seen any discussion yet on Team Update 5 as it relates to photosensor wiring.

R60: Solenoid Breakout outputs shall be connected to pneumatic valve solenoids or photoelectric sensors, PN 42EF-D1MNAK-A2 only. No other devices shall be connected to these outputs

Assuming I read it right, we can wire each photosensor to the solenoid breakouts for power? That could save on breakers and wire runs to the PDB. I like it. I guess then you'd set each Output on the breakout to a logical high to turn on the photosensor (as if you were controlling a solenoid)?

This is clearly useful in light of potential battery voltage drops as the sensors can become erratic if voltage drops too low for too long.

Reading the specs of the NI 9472, it does not appear to provide regulation of the 12 volt supply, so I'm not sure how useful it will be. I have not tried to measure it, however.

Interesting. I hadn't thought about that yet. I wonder why GDC would have gone there if it turns out to not help?...

I guess it does help if you connect it to the cRIO 24v as allowed by <R38>, but not to the 12v from the battery.

using a solenoid module wired for +24 volts takes power from a regulated 24 volt source on the PD. Since the photosensor is speced at 10.8 to 30 volts, this is a perfect solution.
