    概述

    • 數(shù)字量輸入/輸出

    • 用于連接標(biāo)準(zhǔn)開(kāi)關(guān)、2線制接近開(kāi)關(guān)(BERO)、電磁閥、接觸器、低壓電機(jī)、燈和電機(jī)起動(dòng)器

    應(yīng)用

    數(shù)字量輸入/輸出模塊適用于連接：

    • 標(biāo)準(zhǔn)開(kāi)關(guān)和兩線制接近開(kāi)關(guān)(BERO)

    • 電磁閥、接觸器、小功率電機(jī)、燈和電機(jī)啟動(dòng)器

    設(shè)計(jì)

    數(shù)字量輸入/輸出模塊具有下列機(jī)械特性：

    • 緊湊型設(shè)計(jì)：

      • 綠色 LED，用于指示輸入/輸出的信號(hào)狀態(tài)，

      • 插入前連接器

      • 前門上的標(biāo)簽區(qū)

      • 連接器針腳分配，用于在前門內(nèi)部進(jìn)行配線。


    • 安裝簡(jiǎn)單：
      沒(méi)有插槽規(guī)則；輸出地址由插槽決定。
      當(dāng)在 ET 200M 中與有源總線模塊一起使用時(shí)，可以進(jìn)行熱插拔，而不會(huì)有任何反應(yīng)。

    • 方便用戶接線

    功能

    數(shù)字量輸入/輸出模塊轉(zhuǎn)換

    • 來(lái)自過(guò)程的外部數(shù)字信號(hào)電平轉(zhuǎn)換成控制器內(nèi)部信號(hào)電平

    • 將控制器的內(nèi)部信號(hào)電平轉(zhuǎn)換成過(guò)程所要求的外部信號(hào)電平。

    SM 327 是一個(gè)可升級(jí)的I/O模塊。共有16個(gè)通道，其中8個(gè)通道是固定的，另8個(gè)通道可分別用作輸入或輸出。因此，該組和模塊可以靈活地滿足任何組合的需要。
