PLC综合控制柜具(ju)有(you)过载、短路、缺相保护(hu)等(deng)保护(hu)功能。它具(ju)有(you)结构(gou)紧凑、工(gong)(gong)(gong)作(zuo)稳定(ding)、功能很多。可以(yi)根据实(shi)际控(kong)(kong)(kong)制(zhi)规模大小，进行(xing)组合，既可以(yi)实(shi)现(xian)单柜(ju)自(zi)动(dong)控(kong)(kong)(kong)制(zhi)，也(ye)可以(yi)实(shi)现(xian)多柜(ju)通(tong)过工(gong)(gong)(gong)业(ye)以(yi)太网或工(gong)(gong)(gong)业(ye)现(xian)场(chang)总(zong)线网络组成集散(san)（DSC）控(kong)(kong)(kong)制(zhi)系统。 PLC控(kong)(kong)(kong)制(zhi)柜(ju)能适应大小规模的(de)工(gong)(gong)(gong)业(ye)自(zi)动(dong)化(hua)控(kong)(kong)(kong)制(zhi)场(chang)合。应用在(zai)电力、冶金、化(hua)工(gong)(gong)(gong)、造纸(zhi)、污(wu)水处理等(deng)行(xing)业(ye)中(zhong)。

PLC综合控制柜的组成部分：

1、空开：一个总的空气开关，这个是整个柜体的电源控制。相信每个柜子都要有的一个东西。 　　

2、PLC：这(zhei)个要根据工(gong)(gong)程需要选择(ze)。打(da)个比方如果工(gong)(gong)程小可以直(zhi)接就是(shi)一(yi)个一(yi)体化的PLC 但如果工(gong)(gong)程比较大 可能就需要模块(kuai)、卡件(jian)式的，同时还可能需要冗余（也就是(shi)两(liang)套(tao)交替使(shi)用）。

3、24VDC的电(dian)(dian)源(yuan)(yuan)：一个24VDC的开(kai)关电(dian)(dian)源(yuan)(yuan)，大多数的PLC都是自带24VDC的电(dian)(dian)源(yuan)(yuan)，根据是否确实需要来定(ding)是否要这个开(kai)关电(dian)(dian)源(yuan)(yuan)。
