3.2用于模擬量控制
模擬量，如電流、電壓、溫度、壓力等等，它的大小是連續(xù)變化的。工業(yè)生產，特別是連續(xù)型生產過程，常要對這些物理量進行控制。
作為一種工業(yè)控制電子裝置，PLC若不能對這些量進行控制，那是一大不足。為此，各PLC廠家都在這方面進行大量的開發(fā)。目前，不僅大型、中型機可以進行模擬量控制，就是小型機，也能進行這樣的控制。
PLC進行模擬量控制，要配置有模擬量與數(shù)字量相互轉換的A／D、D／A單元。它也是I/O單元，不過是特殊的I/O單元。
A/D單元是把外電路的模擬量，轉換成數(shù)字量，然后送入PLC。D/A單元，是把PLC的數(shù)字量轉換成模擬量，再送給外電路。
