中間繼電器工作原理是:繼電器線圈加電后,常開(kāi)觸點(diǎn)吸合,同時(shí)常閉觸點(diǎn)是自動(dòng)斷開(kāi)中間繼電器:常見(jiàn)是上面是4個(gè)常閉觸點(diǎn),下面是4個(gè)常開(kāi)觸點(diǎn),當(dāng)其線圈通電(AC220V或AC380V)后,利用電磁力把動(dòng)觸頭拉下來(lái),使上面4常閉觸點(diǎn)同時(shí)自動(dòng)斷開(kāi),下面的4常開(kāi)觸點(diǎn)同時(shí)自動(dòng)閉合。誠(chéng)征各區(qū)域經(jīng)銷代理商,歡迎來(lái)電咨詢洽談!服務(wù)電話:13559228117商務(wù)QQ:857475107
