          概述

          • 用于SIMATIC S70-400 的模擬量輸入
          • 用于連接電壓和電流傳感器、熱電耦、電阻和熱電阻
          • 分辨率為 13 到 16 位

          應(yīng)用

          模擬量輸入模板用來實現(xiàn)PLC與模擬量過程信號的連接。 用于連接電壓和電流傳感器、熱電耦、電阻和熱電阻

          設(shè)計

          模擬量輸入模塊具有以下機械特點:

          • 設(shè)計緊湊: 
            堅固的塑料機殼里包括:
            • 前連接器插槽
            • 標(biāo)簽條
          • 安裝簡單
          • 用戶友好的接線: 
            通過插入式前連接器來對模塊接線。

          功能

          模擬量輸入模板將過程模擬量信號轉(zhuǎn)換成S7-400內(nèi)部處理所需的數(shù)字量值。

          該模塊具有以下特性:

          • 分辨率為 13 到 16 位
          • 不同的量程
          • 報警功能
          • 診斷
