5136-DNP-PUI
5136-DNP-PUI5136-DNP-PUI雖然PLC的故障率很低，由PLC構(gòu)成的控制系統(tǒng)可以長(zhǎng)期穩(wěn)定和可靠的工作，單對(duì)它進(jìn)行維護(hù)和檢查是必不可少的。一般每半年應(yīng)對(duì)PLC系統(tǒng)進(jìn)行一次周期性檢查。檢修內(nèi)容包括：
（1）供電電源。 查看PLC的供電電壓是否在標(biāo)準(zhǔn)范圍內(nèi)。交流電源工作電壓的范圍為85～264V，直流電源電壓應(yīng)為24V。（2）環(huán)境條件。 查看控制柜內(nèi)的溫度是否在0～55℃范圍內(nèi)，相對(duì)濕度在35%-85%范圍內(nèi)，以及無(wú)粉塵、鐵屑等積塵。PLC之家 www.plc100.com
（3）安裝條件。 連接電纜的連接器是否完全插入旋緊，螺釘是否松動(dòng)，各單元是否可靠固定、有無(wú)松動(dòng)。
（4）I/O端電壓。 均應(yīng)在工作要求的電壓范圍內(nèi)。
