濕度
為了保持PLC的絕緣特性，通常必須在相對濕度為35%～85%的范圍內(nèi)使用。特別是冬季暖氣時通時斷，有時會因急劇的溫度變化而造成結(jié)露，導致短路而引起誤動作。有此類危險的時候需要在夜間保持電源接通、或者在控制柜內(nèi)設(shè)置加熱器進行微加熱等，以防止結(jié)露現(xiàn)象。（參見圖2）
振動?沖擊
將PLC按照環(huán)境試驗方法（電氣電子）中的正弦波振動試驗法（JISC0040/IEC68-2-6）及沖擊試驗法（JIS C0041/IEC68-2-27）進行試驗,在一般規(guī)格的振動?沖擊下，不應發(fā)生誤動作 但是，不要設(shè)置在經(jīng)常有振動?沖擊，特別是這種振動與沖擊可能直接施加在PLC或控制柜上的場所。
