PLC一般都有三種輸出形式可供用戶選擇,即繼電器輸出,晶體管輸出和晶閘管輸出。在線路結(jié)構(gòu)上都采用了隔離措施。
特點:
繼電器輸出:開關(guān)速度低,負(fù)載能力大,適用于低頻場合。
晶體管輸出:開關(guān)速度高,負(fù)載能力小,適用于高頻場合。
晶閘管輸出:開關(guān)速度高,負(fù)載能力小,適用于高頻場合。
注意事項:
(1) PLC輸出接口是成組的,每一組有一個COM口,只能使用同一種電源電壓。
(2) PLC輸出負(fù)載能力有限,具體參數(shù)請閱讀相關(guān)資料。
(3)對于電感性負(fù)載應(yīng)加阻容保護(hù)。
(4)負(fù)載采用直流電源小于30V時,為了縮短響應(yīng)時間,可用并接續(xù)流二極管的方法改善響應(yīng)時間。
