    • PURPOSE: A motor control center communications system is provided to reduce manufacturing costs and maintenance costs by using a low voltage control wirings. CONSTITUTION: An MCU controller(12) transmits and receives a data signal through a communications network(16) from a plurality of MCU(Motor Control Unit)s(18). The MCU controller is located within a remote panel(14). A magnetic contactor(22) has operable electric contact between an opening and a closed position. A local control module(30) is connected to the magnetic contactor and the MCU controller. The local control module monitors the state of the electric contact transmits the monitored state information to the MCU controller. The local control module operates the magnetic contactor based on the received data signal from the MCU controller.
    • 目的:提供电机控制中心通信系统,通过使用低压控制布线来降低制造成本和维护成本。 构成:MCU控制器(12)通过来自多个MCU(电机控制单元)(18)的通信网络(16)发送和接收数据信号。 MCU控制器位于远程面板(14)内。 电接触器(22)在开口和关闭位置之间具有可操作的电接触。 本地控制模块(30)连接到电磁接触器和MCU控制器。 本地控制模块监视电触点的状态将监视的状态信息发送到MCU控制器。 本地控制模块根据来自MCU控制器的接收数据信号操作电磁接触器。
