No one has mentioned this... What about your power distribution board? I know it's outputting the correct voltage at no load, but it shouldn't be going down to 3V.
How much current is being pulled by the cRIO when you try to run it.
I'm trying to find the power requirements for the cRIO...
EDIT:
Quote:
Power Requirements:
Recommended power supply ................. FIRST Power Distribution Board
24 VDC supply
Power consumption with
I/O modules installed ............................. 20 W maximum
Power supply input range....................... 19 to 30 V

A = W / V
So 20W at 24V = 20W/24V = 10W/12V = 5W/6V = .83A Max
So if you measure the current from the Power Distribution Board to the cRIO, it should not go past .83A. If it does, then it's the cRIO, if not, it's the PDB.
