Driving solenoid valves, driving solenoid actuators, powering lights, saving money, and using parts you already have.
I still don't like the 4 relay ports on the roboRIO because we've used more than four relays multiple times. It seems kind of silly to me that we downgraded from a maximum of 16 relays to 4 on the new controller, considering the driving circuitry for the relays is probably not too complicated.
