數(shù)字量輸入模塊 SIPLUS SM 1221 信號模塊

Overview

為CPU的本機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系統(tǒng)進行后續(xù)擴展
+60 ℃ 到 +70 ℃，最多可同時控制輸入的 50%

注意：

SIPLUS extreme 產(chǎn)品是基于西門子工業(yè)標準產(chǎn)品的。此處列出的內(nèi)容來自相關(guān)的標準產(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)字信號連接。

這為用戶提供了下列優(yōu)勢：

最佳適應(yīng)性：
使用可以根據(jù)需要混合的信號模塊，用戶可以使其控制器準確地滿足相關(guān)任務(wù)的要求。這可以避免產(chǎn)生不必要的投資。可以使用帶有 8 個、16 個和 32 個輸入/輸出通道的模塊。
靈活性：
如果任務(wù)后續(xù)有所擴展，可以升級控制器。更新用戶程序非常簡單。
