Solenoid Bumper

The solenoid valves generally used for FRC are 12 or 24 volt units rated about about one watt, which translates to .083 amps for 12 volts and .042 amps for 24 volts. This is not enough current to justify using the spike solid state relays we use for single speed motor controls, but it is too much current for low current logic outputs. The serve this purpose, FIRST supplies a switch module for the CRIO that is capable of providing .75 amps switched from an external power supply.
