此類故(gu)障在(zai)PLC工作一定(ding)時間(jian)后的(de)故(gu)障中(zhong)經常(chang)發生。在(zai)PLC控(kong)制回路中(zhong)如果出現元器件(jian)損壞故(gu)障，PLC控(kong)制系統(tong)就會立即自(zi)動停止工作。

輸入電路是(shi)PLC接受開關量、模(mo)擬量等(deng)輸入信(xin)號的(de)(de)端口，其元器件質(zhi)量的(de)(de)優劣、接線方(fang)式及是(shi)否牢(lao)靠也是(shi)影響(xiang)控制系(xi)統可靠性的(de)(de)重要因素。

對于開關量輸出(chu)(chu)(chu)來說，PLC的(de)輸出(chu)(chu)(chu)有繼電器輸出(chu)(chu)(chu)、晶閘管(guan)輸出(chu)(chu)(chu)、晶體管(guan)輸出(chu)(chu)(chu)三種形式，具體選擇哪種形式的(de)輸出(chu)(chu)(chu)應根據(ju)負載要(yao)求(qiu)來決定(ding)，選擇不(bu)(bu)當(dang)會使系統(tong)可靠性降低 嚴重時導致系統(tong)不(bu)(bu)能正常工(gong)作。

外接(jie)(jie)繼(ji)電(dian)器(qi)、接(jie)(jie)觸(chu)器(qi)、電(dian)磁(ci)閥等執行元件的質量，是(shi)影(ying)響系統可靠性的重要因素(su)。常見的故(gu)障有線圈(quan)短路(lu)、機械故(gu)障造成觸(chu)點不動或接(jie)(jie)觸(chu)不良。
