Re: Powering two compressors with one PCM

To add to the above,
One and only one compressor on an FRC robot, please.
The PCM is not intended to handle the current of two compressors so a Spike or other relay is your only choice.
The pressure switch is a 3 amp device so it is not an alternative for powering a compressor. Even the smallest compressor teams will use, has a nearly 20 amp start and nearly 10 amps run current. The large Thomas type compressors have a 27 amp start and 12 amp run current.
