Joe,
That would be standard practice in a noisy industrial environment even though it might produce a ground loop to electrical grounds. However, I have several questions as to the status of power to case connections. I am guessing there has been no change but inquiring minds want to know.

This just in...
I have heard from one of my sources that the power connection to case is the same for the 4 slot as for the 8 slot Crio. I will predict that there will be no change in electrical rules. Both Crio types must be insulated from the robot frame.

Interesting stuff, and while we are on the note of different connections, although small it would be interesting to incorporate the DSC into boards mounted directly onto the cRIO modules.
It gets annoyin sometimes when trying to build a super small robot for tests to deal with the extra required space (same goes for such a large PD Board). actually my team uses only 1 part of the DSC and that is 7 PWM connectors.

Then for the intro to the Jaguars, they dont rly fit on small areas as well as the victors, I definately would either like the contuation of Victors or a new compact design.

Cool to see!

Davis,
While it may seem that the PD is large, it's size is in part due to the spacing of the WAGO terminals at each edge, the size and spacing of the breakers and the required width of the circuit board traces needed to supply a low loss (resistance) path for all current flowing through the PD.

true, I didnt think of any of that, I just thought about the "old school" control system and liked how the PWMs are on the controller and the power board is nice and compact.
Although I missed the hay day of those boards and have only actually used them so my team can have 2 bots running at once
