I know they refer to different pieces of hardware (digital sidecar and pnematic breakout), but which one? Do I need to use both of them? What about the "Relay Module and "Relay Channel"?

Thanks

Each Module has a number of different channels on it.

The Pressure Switch DIO Module refers to which slot of the cRIO the module attached to the Digital Sidecar is in. The Pressure Switch DIO Channel refers to the channel number (printed in white on the Digital Sidecar) that the switch is attached to.

The relay module and channel are similarly defined.
