輸入輸出模塊（I/O Module）是連接控制系統(tǒng)（如 PLC、消防主機(jī)）與現(xiàn)場(chǎng)設(shè)備的“橋梁”，核心作用是將外部的開(kāi)關(guān)或模擬信號(hào)轉(zhuǎn)換為系統(tǒng)可識(shí)別的數(shù)字指令，或?qū)⑾到y(tǒng)的控制指令轉(zhuǎn)化為驅(qū)動(dòng)設(shè)備的動(dòng)作信號(hào)。它在工業(yè)自動(dòng)化和消防聯(lián)動(dòng)系統(tǒng)中，既負(fù)責(zé)“感知”外部狀態(tài)，也負(fù)責(zé)“執(zhí)行”控制命令。

輸入輸出模塊主要承擔(dān)兩類任務(wù)，確保控制中樞與現(xiàn)場(chǎng)設(shè)備能“聽(tīng)懂”彼此的語(yǔ)言：

?輸入功能（感知）?：充當(dāng)“信號(hào)翻譯官”。它采集現(xiàn)場(chǎng)按鈕、傳感器、行程開(kāi)關(guān)等的通斷狀態(tài)（如 24V 直流電信號(hào)），通過(guò)光電隔離和抗干擾設(shè)計(jì)，將其轉(zhuǎn)換為控制器能理解的 0/1 邏輯電平或數(shù)字信號(hào)。

?輸出功能（執(zhí)行）?：充當(dāng)“動(dòng)作指揮官”。它將控制器發(fā)出的邏輯指令轉(zhuǎn)換為強(qiáng)驅(qū)動(dòng)信號(hào)，通過(guò)內(nèi)部的繼電器或晶體管輸出，直接控制接觸器、指示燈、閥門等外部設(shè)備的啟停。
