LCU is a dual redundant shared input and output control device designed specifically for rail vehicle
applications. Based on the contactless control and drive technology of signal acquisition and self-diagnosis
technology, it completely replaces the traditional relays in the vehicle electrical control system, directly
controls and drives the train control signals and electrical equipment, fundamentally solves the shortcomings
of the traditional electric contact logic control circuit, improves the safety and reliability of vehicle control,
improves the economy and convenience of operation, and meets the needs of the train control circuit under
the influence of complex environments for improved safety performance.
