DCS為分散控制系統(tǒng)的英文（TOTAL DISTRIBUTED CONTROL SYSTEM）簡稱。指的是控制危險分散、管理和顯示集中。60年代末有人研制了作邏輯運算的可編程序控制器（Programmable Logic Controller）。簡稱PLC。主要應(yīng)用于汽車制造業(yè)。70年代中期以完成模擬量控制的DCS推向市場，代替以PID運算為主的模擬儀表控制。首先提出DCS這樣一種思想的是原制造儀表的廠商，當(dāng)時主要應(yīng)用于化工行業(yè)。后又有計算機(jī)行業(yè)從事DCS的開發(fā)。
DCS分為三大部分，帶I/O板的控制器、通訊網(wǎng)絡(luò)和人機(jī)界面（HMI）。由I/O板通過端子板直接與生產(chǎn)過程相連，讀取傳感器來的信號。I/O板有幾種不同的類型，每一種I/O板都有相應(yīng)的端子板。
模擬量輸入，4-20毫安的標(biāo)準(zhǔn)信號板和用以讀取熱電偶的毫伏信號板；4-16個通道不等；
模擬量輸出，通常都是4-20毫安的標(biāo)準(zhǔn)信號，一般它的通道比較少，4-8個個通道；
開關(guān)量輸入；16-32個通道：
開關(guān)量輸出，開關(guān)量輸入和輸出還分不同電壓等級的板，如直流24伏、125伏；交流220伏或115伏等；8-16個通道不等；
脈沖量輸入，用于采集速率的信號；4-8通道不等；
快速中斷輸入；
HART協(xié)議輸入板；
現(xiàn)場總線I/O板；
