ASTRO VG-827

.I/O模塊

各I/O點的通/斷狀態用發光二極管（LED）顯示，PLC與外部接線的連接一般用接線端子，某些模塊使用可以拆卸的插座型端子板，不需斷開端子板上的連接線，就可以迅速的更換模塊。

輸入模塊：PLC通過輸入模塊來接收和采集輸入信號，通過輸出模塊控制接觸器、電磁閥、電磁鐵、調速裝置等執行器，PLC控制的另一類外部負載是指示燈、數字顯示裝置和報警裝置等。輸入電路中設有RC濾波電路，以防止由于輸入觸點抖動或外部干擾脈沖引起的錯誤輸入信號。

輸出模塊：輸出模塊的率放大元件有大功率晶體管和場效應管（驅動直流負載）、雙向可控硅（驅動交流負載）和小型繼電器，繼電器可以驅動交流負載或直流負載。輸出電流的典型值為0.5—2A，負載電源由外部現場提供。
