SM 1222 数字量输出模块
Overview
·为CPU的本机I/O提供更多的数字量输出
·用于使控制器灵活地适应相关任务的要求
·用于使用附加输出对系统进行后续扩展
Area of application
数字量输出模块允许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 1222 数字量输出信号模块将 SIMATIC S7-1200 的内部信号电平转换为过程所需的外部信号电平。
