Wiring a Flashlight, 2013 version

[Cal578]

R53 is about solenoids. I think you meant R54, which says:

Custom circuits shall not directly alter the power pathways between the ROBOT battery, PD Board, motor controllers, relays, motors, or other elements of the ROBOT control system (including the power pathways to other sensors or circuits). ...

The "Custom circuit" in this case is just the flashlight (and the wire that goes between the relay and the flashlight). So, the custom circuit is not altering the power pathway to anything else, so it doesn't violate R54.

The text at the bottom of Table 4-4 says:

Multiple low-load, pneumatic solenoid valves or lights may be connected to a single relay module. This would allow one (1) relay module to drive multiple pneumatic actions or multiple lights. No other electrical load can be connected to a relay module used in this manner.

(emphasis mine)

So, it seems pretty clear that a relay to turn the flashlight on and off isn't violating R52 (Table 4-4) either.
