1756-L61 处理器模块
PLC控制器属高速低电平控制装置，应采用直接接地方式。为了抑制加在电源及输入端、输出端的干扰，应给PLC控制器接上专用地线，接地点应与动力设备的接地点分开。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控制器。集中布置的PLC控制器适于并联一点接地方式，各装置的柜体中心接地点以单独的接地线引向接地极。分散布置的PLC控制器，应采用串联一点接地方式。接地极的接地电阻小于2Ω，接地极最好埋在距建筑物10～15m远处，而且PLC控制器接地点必须与强电设备接地点相距10m以上。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。
信号源接地时，屏蔽层应在信号侧接地；信号源不接地时，应在PLC控制器侧接地。信号线中间有接头时，屏蔽层应牢固连接并进行绝缘处理，各屏蔽层应相互连接好。选择适当的接地处单点接地，要避免多点接地。
