PLC進(jìn)行模擬量控制，要配置有模擬量與數(shù)字量相互轉(zhuǎn)換的A／D、D／A單元。它也是I/O單元，不過(guò)是特殊的I/O單元。

    A/D單元是把外電路的模擬量，轉(zhuǎn)換成數(shù)字量，然后送入PLC。D/A單元，是把PLC的數(shù)字量轉(zhuǎn)換成模擬量，再送給外電路。

    作為一種特殊的I/O單元，它仍具有I/O電路抗干擾、內(nèi)外電路隔離，與輸入輸出繼電器（或內(nèi)部繼電器，它也是PLC工作內(nèi)存的一個(gè)區(qū)。可讀寫(xiě)）交換信息等等特點(diǎn)。

    這里的A/D中的A，多為電流，或電壓，也有為溫度。D/A中的A，多為電壓，或電流。電壓、電流變化范圍多為0～5V，0～10V，4～20mA。有的還可處理正負(fù)值的。備貨，備貨，降降降，火火火，火火火……
