信号电路接地的目的:保证信号具有稳定的基准电位。为使电子设备工作时有一个统一的参考电位,避免有害电磁场的干扰,使电子设备稳定可靠的工作,电子设备中的信号电路应接地,简称为信号地。信号接地与电源接地有什么区别?电源地主要是针对电源回路电流所走的路径而言的,一般来说电源地流过的电流较大,而信号地主要是针对两块芯片或者模块之间的通信信号的回流所流过的路径,一般来说信号地流过的电流很小,其实两者都是GND,之所以分开来说,是想让大家明白在布PCB板时要清楚地了解电源及信号回流各自所流过的路径,然后在布板时考虑如何避免电源及信号共用回流路径,如果共用的话,有可能会导致电源地上大的电流会在信号地上产生一个电压差(可以解释为:导线是有阻抗的,只是很小的阻值,但如果所流过的电流较大时,也会在此导线上产生电位差,这也叫共阻抗干扰),使信号地的真实电位高于0V,如果信号地的电位较大时,有可能会使信号本来是高电平的,但却误判为低电平。

不要管它是进口、国产,应用是否广泛,这些都不是现在应该考虑的问题。就像学习游泳一样,首先要做的就是,找个水浅的地方跳进去,先扑腾几下。入门是学习三菱还是西门子?有三菱的基础了,多久能学会西门子的PLC?这些不是问题,任何一款入门后,再换其他品牌都能很快上手。PLC技术是门实用技能,想掌握它,就从你面前的这个开始。误区找别人要资料这里说的找别人要资料,是那种胡子眉毛一把抓的拷贝,不去区分是否适合自己。
