Overview
●为CPU的本机I/O提供更多的数字量输入/输出
●灵活地选择控制器以满足相应任务需要
●用于使用附加输入端和输出端对系统进行后续扩展
●+60 ℃ 到 +70 ℃,最多可同时控制输入的 50%
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 I/O 模块允许:
●将控制器与过程中的数字信号连接
●将数字信号从控制器输出到过程
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 1223 数字量输入/输出信号模块
●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,
●还可将 SIMATIC S7-1200 的内部信号电平转换为过程所需的外部信号电平。
