注意：

SIPLUS extreme 产品是基于西门子工业标准产品的。此处列出的内容来自相关的标准产品。添加了特定 SIPLUS extreme 信息

Area of application

数字量输入模块允许将控制器与过程中的数字信号连接。

这为用户提供了下列优势：

●最佳适应性：

使用可以根据需要混合的信号模块，用户可以使其控制器准确地满足相关任务的要求。这可以避免产生不必要的投资。可以使用带有 8 个、16 个和 32 个输入/输出通道的模块。

●灵活性：

如果任务后续有所扩展，可以升级控制器。更新用户程序非常简单。

Functions

SM 1221 数字量输入信号模块将过程中的外部数字信号电平转换为 S7-1200 的内部信号电平。
