                  各位路過(guò)的大神，plc有幾個(gè)SM1231的模擬量輸入模塊和兩個(gè)SM1232模擬輸入模塊，輸入模塊能否同時(shí)接以24V電源輸出4-20ma的傳感器和以220V電源輸出4-20ma的傳感器��？？輸出模塊也是4-20ma接在剛加的220V電源的執行機構上的
    
                
                因為之前的都是接的24V電源的傳感器，現在加了一個(gè)220V的輸入、輸出4-20ma的傳感器后，整個(gè)PLC的信號突然中斷都沒(méi)了，像是PLC卡死一樣，是不是要更換這個(gè)傳感器，或者加隔離模塊，還或者是因為加的模擬量模塊太多，總電源功率不夠啊，請高手多多指教？

                請指教，感謝！
