What you describe is forbidden by Rule <R78>:
<R78> The Nason pressure switch must be connected to the high-pressure side of the pneumatic circuit (i.e. prior to the pressure regulator) to sense the “stored” pressure of the circuit. The two wires from the pressure switch
must be connected directly to a digital input and ground port on the Digital Sidecar, and the cRIO-FRC
must be programmed to sense the state of the switch and operate the relay module that powers the compressor to prevent over-pressuring the system.
I don't know why your approach is not allowed. Perhaps someone with further insight could shed some light.
