在输入、输出端接感性负载时，要在负载两端并联一个冲击抑制器或二极管，二极管的阴极与电压㈩极侧连接。

外部互锁与接地

利用PLC控制电机正反转等正、反动作时，为避免PC的异常动作引起事故及机械损坏，应在外部组成一个连锁回路。

接地：GR端子是大地接地端子。用防止感应电的接地线(截面积2mm2以上的电线)采用第三种接地方式(接地电阻100Ω以下)。

LG是噪音滤波器中性端子，若因噪音大而产生误动作，或为了防止电击，把LG与GR短接，采用第三种接地方式。接地线的长度在20m以内为宜。

接地线与其它设备共用或与建筑物的金属结构连接会适得其反，受到恶劣影响。

PLC外部驱动电路

对于PLC输出不能直接带动负载的情况下，在外部采用驱动电路，可以用固态继电器或晶闸管电路驱动，同时应采用保护电路和浪涌吸收电路。
