DIGITAL OUTPUT CONTROL DEVICE AND METHOD FOR OPERATING

摘要

Apparatus and method are presented for a solid state relay module suitable for accepting low-level digital signals from a digital computer, and for providing on/off control of heavy electrical loads. The relay and its methods are intended for electrically hostile environments such that the relay may be exposed to spurious high voltages either on its input or on its load circuit. This relay and its methods are particularly intended for use in a locomotive throttle controller. The relay accepts low-level digital signals from a central processor computer in the throttle controller, and provide high-power digital signals to the trainlines which control the engine of the locomotive.
