SX-1

The SX-1 is a high reliability design for isolating both the battery negative and power to the ignition system on comand, thus stopping the engine and preventing the alternator voltage supplying the car with power to continue. The unit's performance is continually monitored with an onboard microprocessor which also provides diagnostic information. Switching current levels and temperatures are monitored and controlled within safe limits on both negative and power outputs. The command signals are supplied to the unit from low voltage signals via manually controlled switches inside the cockpit for the driver and outside the car for use by track marshalls in case of an emergency.
