Summary:PURPOSE: An electric actuator control device for valve drive using an I2C bus is provided to reduce the time and cost for manufacture because of simplified wiring and facilitate the application of options. CONSTITUTION: An electric actuator control device for valve drive comprises a CPU board(100), a terminal board(200), a power board(300), a limit switch board(400), an I2C bus(500), and a motor(600). The CPU board comprises a CPU(101), a display(102), and a local switch. The terminal board receives three-phase power source and remote commands and outputs signals through a relay. The power board comprises a three-phase sensing circuit and a reversible contactor. The limit switch board transmits the current opening degree of an actuator as variation in resistances of limit switches and potentiometers. The I2C bus connects the modules.
