產(chǎn)品詳情

概述

數(shù)字量輸入/輸出
用于連接標(biāo)準(zhǔn)開關(guān)、2線制接近開關(guān)(BERO)、電磁閥、接觸器、低壓電機(jī)、燈和電機(jī)起動器

應(yīng)用

數(shù)字量輸入/輸出模塊適用于連接：

標(biāo)準(zhǔn)開關(guān)和兩線制接近開關(guān)(BERO)
電磁閥、接觸器、小功率電機(jī)、燈和電機(jī)啟動器

設(shè)計

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：
- 綠色 LED，用于指示輸入/輸出的信號狀態(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。
安裝簡單：
沒有插槽規(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，可以進(jìn)行熱插拔，而不會有任何反應(yīng)。
方便用戶接線

功能

數(shù)字量輸入/輸出模塊轉(zhuǎn)換

來自過程的外部數(shù)字信號電平轉(zhuǎn)換成控制器內(nèi)部信號電平
將控制器的內(nèi)部信號電平轉(zhuǎn)換成過程所要求的外部信號電平。

SM 327 是一個可升級的I/O模塊。共有16個通道，其中8個通道是固定的，另8個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。
