Dear NI, please consider a future hardware feature addition:
Add a "Power Up Delay DIP Switch" to the back of the PXI Power Supply Shuttle.
It would allow end users to reliably sequence the powering-up of multi PXI chassis solutions. It could also be handy to sequence any other boot-order sensitive equipment in the rack or subsystem. This would also be a world-voltage solution since this capability already exists in the power shuttle. We are seeing the need for more input-voltage-agnostic solutions. I'm sure you are too.
It might offer time delay choices of 1,2,4,8,16 seconds, etc.
We run into this problem on every multi-chassis integration. We have solved it several ways in the past like: human procedure (error prone), sequencing power strips ($$$ and not world-voltage capable), custom time-delay relays ($$$).
Imagine never having your downstream chassis(s) disappear. Or worse yet, having them show up in MAX, but act strangely because of not enough delay time between boots.
Thanks for reading this, and consider tossing me a Kudos!
Despite having dedicated RTD cards on other platforms, this doesn't exist on PXI. The existing bridge input cards have significantly higher sample rates than needed for typical temperature measurements, and it would be nice to have a more economical drop-in option for RTDs that supported more channels.
