PLC控制柜是指可編程控制柜，控(kong)制(zhi)(zhi)柜是指控(kong)制(zhi)(zhi)電(dian)機和開關(guan)的成(cheng)套控(kong)制(zhi)(zhi)柜。PLC控(kong)制(zhi)(zhi)柜具(ju)有(you)過(guo)載(zai)、短路、缺(que)相保(bao)(bao)護等(deng)保(bao)(bao)護功能。PLC綜(zong)合控(kong)制(zhi)(zhi)柜具(ju)有(you)過(guo)載(zai)、短路、缺(que)相保(bao)(bao)護等(deng)保(bao)(bao)護功能。結構(gou)緊湊，工作穩定，功能齊全。根據實(shi)際(ji)控(kong)制(zhi)(zhi)規定，可(ke)實(shi)現單柜自動控(kong)制(zhi)(zhi)，通過(guo)工業(ye)以太(tai)網(wang)或工業(ye)現場總線網(wang)絡形成(cheng)多柜配(pei)送（DCS）控(kong)制(zhi)(zhi)系統。PLC控(kong)制(zhi)(zhi)柜能適應各種工業(ye)自動化控(kong)制(zhi)(zhi)場合。廣泛(fan)應用于電(dian)力(li)、冶金、化工、造紙(zhi)、環保(bao)(bao)污水處(chu)理等(deng)行業(ye)。

  PLC控(kong)制(zhi)(zhi)(zhi)(zhi)柜是現(xian)代工(gong)(gong)業(ye)(ye)的(de)(de)(de)核心和(he)靈魂，具有設(she)備自動化(hua)(hua)(hua)和(he)工(gong)(gong)藝自動化(hua)(hua)(hua)控(kong)制(zhi)(zhi)(zhi)(zhi)、網絡功能(neng)(neng)(neng)(neng)完(wan)善、性能(neng)(neng)(neng)(neng)穩定、可(ke)(ke)(ke)擴展、抗干擾強等(deng)特點(dian)。PLC控(kong)制(zhi)(zhi)(zhi)(zhi)柜、變頻柜等(deng)。可(ke)(ke)(ke)根(gen)據(ju)(ju)用戶需求(qiu)量(liang)身定制(zhi)(zhi)(zhi)(zhi)，滿(man)足用戶需求(qiu)，并可(ke)(ke)(ke)合人機(ji)界面觸摸屏，達到(dao)操(cao)作方便(bian)的(de)(de)(de)目的(de)(de)(de)。該設(she)備還可(ke)(ke)(ke)以(yi)傳輸DCS總線上(shang)位機(ji)modbus、profibus等(deng)通信協(xie)議的(de)(de)(de)數(shu)據(ju)(ju)；工(gong)(gong)控(kong)機(ji)、以(yi)太(tai)網等(deng)的(de)(de)(de)控(kong)制(zhi)(zhi)(zhi)(zhi)和(he)監控(kong)。PLC控(kong)制(zhi)(zhi)(zhi)(zhi)柜種類繁(fan)多，但由于其產品系列化(hua)(hua)(hua)、模(mo)塊(kuai)化(hua)(hua)(hua)、軟件包裝(zhuang)齊全，用戶可(ke)(ke)(ke)靈活形成(cheng)不同規模(mo)、不同要求(qiu)的(de)(de)(de)控(kong)制(zhi)(zhi)(zhi)(zhi)系統(tong)。現(xian)代PLC除了邏輯處理(li)功能(neng)(neng)(neng)(neng)外，還具有完(wan)善的(de)(de)(de)數(shu)據(ju)(ju)操(cao)作能(neng)(neng)(neng)(neng)力，可(ke)(ke)(ke)用于各種控(kong)制(zhi)(zhi)(zhi)(zhi)領域。近年來，PLC出(chu)現(xian)了大量(liang)的(de)(de)(de)功能(neng)(neng)(neng)(neng)單元，將(jiang)PLC的(de)(de)(de)應用擴展到(dao)位置(zhi)控(kong)制(zhi)(zhi)(zhi)(zhi)、溫度控(kong)制(zhi)(zhi)(zhi)(zhi)、數(shu)控(kong)等(deng)工(gong)(gong)業(ye)(ye)控(kong)制(zhi)(zhi)(zhi)(zhi)。隨(sui)著PLC通信能(neng)(neng)(neng)(neng)力的(de)(de)(de)提高和(he)人機(ji)界面技術的(de)(de)(de)發展，PLC更容易形成(cheng)各種控(kong)制(zhi)(zhi)(zhi)(zhi)系統(tong)。
