隨著PLC控制的普及與應(yīng)用，PLC產(chǎn)品的種類和數(shù)量越來(lái)越多，而且功能也日趨完善。近年來(lái)，從美國(guó)、日本、德國(guó)引進(jìn)的PLC產(chǎn)品及國(guó)內(nèi)廠家組裝或自行開(kāi)發(fā)的產(chǎn)品已有幾十個(gè)系列，上百種型號(hào)。目前在國(guó)內(nèi)應(yīng)用較多地PLC產(chǎn)品主要包括：美國(guó)AB、GE、MODICON公司，德國(guó)西門(mén)子公司，日本OMRON、三菱公司等得PLC產(chǎn)品。因此PLC的品種繁多，其結(jié)構(gòu)形式、性能、容量、指令系統(tǒng)、編程方法、價(jià)格等各有自己的特點(diǎn)，適用場(chǎng)合也各有側(cè)重。因此，合理選擇PLC，對(duì)于提高PLC控制系統(tǒng)的技術(shù)經(jīng)濟(jì)指標(biāo)起著重要的作用。一般選擇機(jī)型要以滿足系統(tǒng)功能需要為宗旨，不要盲目貪大求全，以免造成投資和設(shè)備資源的浪費(fèi)。機(jī)型的選擇可從以下幾個(gè)方面慮。?PLC的I/O響應(yīng)時(shí)間包括輸入電路延遲、輸出電路延遲和掃描工作方式引起的時(shí)間延遲（一般在2～3個(gè)掃描周期）等。對(duì)開(kāi)關(guān)量控制的系統(tǒng)，PLC和I/O響應(yīng)時(shí)間一般都能滿足實(shí)際工程的要求，可不必考慮I/O響應(yīng)問(wèn)題。但對(duì)模擬量控制的系統(tǒng)、特別是閉環(huán)系統(tǒng)就要考慮這個(gè)問(wèn)題。?不同的負(fù)載對(duì)PLC的輸出方式有相應(yīng)的要求。例如，頻繁通斷的感性負(fù)載，應(yīng)選擇晶體管或晶閘管輸出型的，而不應(yīng)選用繼電器輸出型的。但繼電器輸出型的PLC有許多優(yōu)點(diǎn)，如導(dǎo)通壓降小，有隔離作用，價(jià)格相對(duì)較便宜，承受瞬時(shí)過(guò)電壓和過(guò)電流的能力較強(qiáng)，其負(fù)載電壓靈活（可交流、可直流）且電壓等級(jí)范圍大等。所以動(dòng)作不頻繁的交、直流負(fù)載可以選擇繼電器輸出型的PLC。
