PLC運用中應(yīng)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(shè)備時不能放在發(fā)熱量大的元件下面,附近通風(fēng)散熱的空間應(yīng)滿意大,根本單元和拓寬單元之間要有30mm以上距離;開關(guān)柜上、下部應(yīng)有通風(fēng)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(shè)備電風(fēng)扇強迫通風(fēng)。
2. 濕度
為了確保PLC的絕緣功用,空氣的相對濕度應(yīng)小于85%(無凝露)。
3. 轟動
應(yīng)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(dāng)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(guān)于空氣中有較多粉塵或腐蝕性氣體的環(huán)境,可將PLC設(shè)備在封閉性較好的操控室或操控柜中,并設(shè)備空氣凈化設(shè)備。
5. 電源
PLC供電電源為50Hz、220(1±10%)V的溝通電,關(guān)于電源線來的攪擾,PLC自身具有滿意的抵抗才能。關(guān)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(shè)備一臺帶屏蔽層的變比為1:1的阻隔變壓器,以削減設(shè)備與地之間的攪擾。還可以在電源輸入端串接LC濾波電路。
