摘要

PURPOSE: A light control system with an override function is provided to apply various relays by adding a synchronization function which equally maintains data and a relay state value. CONSTITUTION: A CPU unit controls all functions of a relay controller. A communication unit charges communication between a light master controller and the CPU unit. A relay driver drives a relay. A relay state display unit displays a relay control state. A relay state storage unit stores a relay state when the relay is driven.
