在PLC控制系統(tǒng)設(shè)計(jì)中接線(xiàn)的工作比重叫小，但它是編程設(shè)計(jì)的基礎(chǔ)。要保證接線(xiàn)工作正確性，需PLC的輸入輸出電路有一個(gè)清楚的了解。

1.PLC直流輸入電路：分有源型（共陽(yáng)極）輸入電路，漏型（共陰極）輸入電路。所以漏型輸入電路PLC的COM端是外接直流電源的正極，如西門(mén)子S7-400PLC直流輸入模塊的COM端接外部電源的正極。所以西門(mén)子PLC輸入信號(hào)為低壓信號(hào),如果外部信號(hào)為高壓信號(hào)應(yīng)該通過(guò)中間繼電器轉(zhuǎn)換。

2.PLC交流輸入電路電壓一般為AC120V或AC230V，經(jīng)過(guò)電阻的限流和電容的隔離在經(jīng)過(guò)整流變成直流三個(gè)環(huán)節(jié)，所以輸入信號(hào)延遲時(shí)間比直流電路長(zhǎng)，但是輸入端是高電壓，輸入信號(hào)的可靠信高，一般用于環(huán)境惡劣，對(duì)響應(yīng)要求不高的場(chǎng)合。
