輸出接口
PLC的繼電器輸出接口電路
工作過程：當(dāng)內(nèi)部電路輸出數(shù)字信號1，有電流流過，繼電器線圈有電流，然后常開觸點閉合，提供負(fù)載導(dǎo)通的電流和電壓。當(dāng)內(nèi)部電路輸出數(shù)字信號0，則沒有電流流過，繼電器線圈沒有電流，然后常開觸點斷開，斷開負(fù)載的電流或電壓。也就是通過輸出接口電路把內(nèi)部的數(shù)字電路化成一種信號使負(fù)載動作或不動作。

三種類型：
繼電器輸出：有觸點、壽命短、頻率低、交直流負(fù)載
晶體管輸出：無觸點、壽命長、直流負(fù)載
晶閘管輸出：無觸點、壽命長、交流負(fù)載
