two soleniods controlled by one relay

No, the NI 9472 is printed to look like a simple SPST switch. So is the photosensor, and that's not a relay either.

That makes it sound like two solenoids is the limit. Do you just mean to say that the total load of all solenoids must be less than or equal to the 0.75 A capability of the output?

Exception: Multiple low-load, pneumatic solenoid valves may be connected to a single relay module. This would allow one relay module to drive multiple pneumatic actions. No other electrical load can be connected to a relay module used in this manner.

How does <R42> apply? The NI 9472 is neither a speed controller nor a relay module.
