1、DCS控制系統(tǒng)AO點(diǎn)數(shù)如何計(jì)算
AO指DCS系統(tǒng)或PLC發(fā)出的控制現(xiàn)場(chǎng)執(zhí)行設(shè)備的模擬量輸出信號(hào)。AO輸出一般有4-20mA、0-20mA、0-5V、1-5V和0-10V五種類(lèi)型,4-20mA為最常用DCS系統(tǒng)AO輸出,AO輸出通常接入電動(dòng)執(zhí)行機(jī)構(gòu)、氣動(dòng)執(zhí)行機(jī)構(gòu)、變頻器、電力調(diào)整器和工業(yè)控制模塊等設(shè)備,通常每一個(gè)被控對(duì)象對(duì)應(yīng)一路AO輸出,AO輸出點(diǎn)數(shù)與被控設(shè)備數(shù)量相同。
2、DCS控制系統(tǒng)DI點(diǎn)數(shù)如何計(jì)算
DI指進(jìn)入DCS系統(tǒng)或PLC的開(kāi)關(guān)量輸入信號(hào),DI輸入必須是無(wú)源觸點(diǎn)、TTL或CMOS電平信號(hào),DI進(jìn)入DCS系統(tǒng)或PLC后通常會(huì)接通DC24V或者DC48V查詢(xún)電壓。儀表專(zhuān)業(yè)DI輸入通常來(lái)自現(xiàn)場(chǎng)電接點(diǎn)壓力表、電接點(diǎn)雙金屬溫度計(jì)、電接點(diǎn)水位計(jì)、液位開(kāi)關(guān)、流量開(kāi)關(guān)、火焰檢測(cè)、電接點(diǎn)水位計(jì)等儀表的報(bào)警觸點(diǎn),每一個(gè)報(bào)警觸點(diǎn)接入DCS系統(tǒng)時(shí)計(jì)算為一個(gè)點(diǎn)DI輸入。
