Non-FRC Motor Controller?

Where did you find this information? It's totally wrong.

Spike relay modules contain a pair of simple physical relays that use a pair of logic level signals to independently switch each relay's output between the 12 volt power and "ground" return inputs. When wired to motors, both relays are usually connected in an H-bridge configuration, but they don't have to be used that way. They are just as easily used as separate circuits, such as when powering LEDs or pneumatic solenoid valves.

Pulsing them is not recommended, as they are rated for a finite number of cycles and are likely to fail either electrically or mechanically.
