● PLC的输入与输出分开走线，开关量与模拟量也要分开敷设。模拟量信号的传送应采用屏蔽线，屏蔽层应一端或两端接地，接地电阻应小于屏蔽层电阻的1/10.

　　● 交流输出线和直流输出线不要用同一根电缆，输出线应尽量远离高压线和动力线，避免并行。

　　（3）I/O端的接线

　　输入接线

　　● 输入接线一般不要太长。但如果环境干扰较小，电压降不大时，输入接线可适当长些。

　　● 输入/输出线不能用同一根电缆，输入/输出线要分开。

　　● 尽可能采用常开触点形式连接到输入端，使编制的梯形图与继电器原理图*，便于阅读。

　　输出连接

　　● 输出端接线分为独立输出和公共输出。在不同组中，可采用不同类型和电压等级的输出电压。但在同一组中的输出只能用同一类型、同一电压等级的电源。
