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)存的一個區(qū)。可讀寫）交換信息等等特點。
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。
這里的D，小型機(jī)多為8位二進(jìn)制數(shù)，中、大型多為12位二進(jìn)制數(shù)。
A/D、D/A有單路，也有多路。多路占的輸入輸出繼電器多。
有了A/D、D/A單元，余下的處理都是數(shù)字量，這對有信息處理能力的PLC并不難。中、大型PLC處理能力更強(qiáng)，不僅可進(jìn)行數(shù)字的加、減、乘、除，還可開方，插值，還可進(jìn)行浮點運(yùn)算。有的還有PID指令，可對偏差制量進(jìn)行比例、微分、積分運(yùn)算，進(jìn)而產(chǎn)生相應(yīng)的輸出。計算機(jī)能算的它幾乎都能算?！?/span>
