1、對發(fā)光二極管（包括光耦器件）其限流電阻選擇應確保二極管電流在8~10mA為好，如電流太小其發(fā)光亮度低（不亮），對光耦器件來說由于發(fā)光亮度低使其光耦合效果變差。故圖中的10K電阻應該為2~3KΩ。
2、如果PLC的24V電源與電磁閥電源是用同一個電源的話，可以省掉光耦器件，畫成像我畫的電路一樣，這可大大簡化電路，故可減少故障點。

從圖中可知，你用的PLC可能是三菱牌的，其輸出電路為負邏輯，即：24V電源的正極接COM公共點，輸出開關(guān)（繼電器觸點或晶體管開關(guān)）接在輸出口（Yn）與24V電源的負，這樣所用晶體管應為PNP型，就可組成zui簡輸出電路，見下圖：
