除了為特殊工作而設(shè)計(jì)的PLC外,一般PLC工作的溫度應(yīng)在0~55℃的范圍,并要避免太陽(yáng)光直接照射;安裝時(shí)要遠(yuǎn)離大的熱源,保證足夠大的散熱空間和通風(fēng)條件;空氣的相對(duì)濕度應(yīng)小于85%,不結(jié)露,以保證PLC的絕緣良好。PLC應(yīng)避免安裝在有振動(dòng)的場(chǎng)所;對(duì)振動(dòng)源允許的條件則應(yīng)按照產(chǎn)品說(shuō)明書(shū)的要求,安裝減振橡膠凋采取其他防振措施??諝庵杏蟹蹓m和有害氣體時(shí),應(yīng)將PLC封閉安裝。 1.2 電源的要求 不同的PLC產(chǎn)品,對(duì)電源的要求也不同,這里包括電源的電壓等級(jí)、、交流紋波系數(shù)和輸入輸出的供電等。 對(duì)電磁較強(qiáng)、而對(duì)PLC可靠性要求又較高的,PLC的供電應(yīng)與動(dòng)力供電和控制電路供電分開(kāi);必要時(shí),可采用帶屏蔽的隔離變壓器供電、串聯(lián)LC濾波電路等。在設(shè)計(jì)時(shí),外接的直流電源應(yīng)采用穩(wěn)壓電源,供電功率應(yīng)留有20%~30%的余量。對(duì)由控制器本身提供的直流電源,應(yīng)了解它所能提供的大電流,防止過(guò)電流造成設(shè)備的損壞。
