PLC運用中應留意的疑問
一、作業(yè)環(huán)境
1． 溫度
PLC請求環(huán)境溫度在0~55℃，設備時不能放在發(fā)熱量大的元件下面，附近通風散熱的空間應滿意大，根本單元和拓寬單元之間要有30mm以上距離；開關柜上、下部應有通風的百葉窗，防止太陽光直接照耀；假如周圍環(huán)境超越55℃，要設備電風扇強迫通風。
2． 濕度
為了確保PLC的絕緣功用，空氣的相對濕度應小于85%（無凝露）。
3． 轟動
應使PLC遠離激烈的轟動源，防止振蕩頻率為10~55Hz的頻頻或接連振蕩。當運用環(huán)境不行防止轟動時，有必要采納減震辦法，如選用減震膠等。
4． 空氣
防止有腐蝕和易燃的氣體，例如氯化氫、硫化氫等。關于空氣中有較多粉塵或腐蝕性氣體的環(huán)境，可將PLC設備在封閉性較好的操控室或操控柜中，并設備空氣凈化設備。
5． 電源
PLC供電電源為50Hz、220（1±10%）V的溝通電，關于電源線來的攪擾，PLC自身具有滿意的抵抗才能。關于牢靠性請求很高的場合或電源攪擾特別嚴峻的環(huán)境，可以設備一臺帶屏蔽層的變比為1：1的阻隔變壓器，以削減設備與地之間的攪擾。還可以在電源輸入端串接LC濾波電路。
