數(shù)字量輸入模塊 SIPLUS SM 1221 信號(hào)模塊


Overview

  • 為CPU的本機(jī)I/O提供更多的數(shù)字量輸入
  • 靈活地選擇控制器以滿足相應(yīng)任務(wù)需要
  • 用于使用附加輸入對(duì)系統(tǒng)進(jìn)行后續(xù)擴(kuò)展
  • +60 ℃ 到 +70 ℃，最多可同時(shí)控制輸入的 50%
注意：

SIPLUS extreme 產(chǎn)品是基于西門子工業(yè)標(biāo)準(zhǔn)產(chǎn)品的。此處列出的內(nèi)容來自相關(guān)的標(biāo)準(zhǔn)產(chǎn)品。添加了特定 SIPLUS extreme 信息


Area of application

數(shù)字量輸入模塊允許將控制器與過程中的數(shù)字信號(hào)連接。

這為用戶提供了下列優(yōu)勢(shì)：

  • 最佳適應(yīng)性：
    使用可以根據(jù)需要混合的信號(hào)模塊，用戶可以使其控制器準(zhǔn)確地滿足相關(guān)任務(wù)的要求。這可以避免產(chǎn)生不必要的投資?？梢允褂脦в?8 個(gè)、16 個(gè)和 32 個(gè)輸入/輸出通道的模塊。
  • 靈活性：
    如果任務(wù)后續(xù)有所擴(kuò)展，可以升級(jí)控制器。更新用戶程序非常簡(jiǎn)單。
