FIRST probably won't allow any custom components in the power pathway. Only official KOP relays and speed controllers.

Rather, an active device is one that modifies the signal sent to the Talon or Spike (or Jag or Vic). If the connection to a speed controller is not directly from the roboRIO pins or MXP headers, through passive devices (PCBs, bumpers, etc.), to the speed controller signal port, then the intermediate device has to be approved in advance.
