良好的接地是保证PLC可靠工作的重要条件,可以避免偶然发生的电压冲击危害。接地线与机器的接地端相接,基本单元接地。如果要用扩展单元,其接地点应与基本单元的接地点接在一起。为了抑制加在电源及输入端、输出端的干扰,应给可编程控制器接上专用地线,接地点应与动力设备(如电机)的接地点分开。若达不到这种要求,也必须做到与其他设备公共接地,禁止与其他设备串联接地。接地点应尽可能靠近PLC直流24伏接线端PLC上的24伏接线端子,还可以向外部传感器(如接近传感器)提供电流。24伏端子作传感器电源时,COM端子是直流24伏地端。如果采用扩展单元,则应将基本单元和扩展单元的24伏端连接起来。另外,任何外部电源不能接到这个端子上。ADVANCED ENERGY Power Supply 2194-015-T
