PLC系统接地
1、接地就是让已经纳入防雷系统的闪电能量泄放入大地，良好的接地才能有效地降低引下线上的电压,避免发生反击。接地是防雷系统中最基础的环节。接地不好，所有防雷措施的防雷效果都不能发挥出来。
2、案例分析：数字地和模拟地建议分开（除非你的低压电气设备电源电压只有几十伏），因为数字电路属于正负5V、12V、24V级别的，很容易受干扰，而且一旦外部异常电压一旦串入将很大可能性的造成设备损坏。我刚上班时工厂里有一台1000吨的萨克米压砖机，因为其它设备和数字地的原因导致其电子设施几次烧毁，***意大利派过来的技师（才毕业的中专生）更换设备后，指挥人在就地挖了个坑，埋了一根接地铜管和接地填料，搞成了单独接地。***再也没有出现过类似现象。
