- 用于SIMATIC S7-1200 的模拟量输入
- 极短的转换时间
- 用于连接模拟传感器，无需附加放大器
- 用于应对更为复杂的自动化任务
Area of application
SM 1231 模拟量输入信号模块允许将控制器与过程中的模拟信号连接。
这为用户提供了下列优势：
- 优秀适应性：
使用模拟信号模块，用户可以使其控制器优秀地满足更加复杂的任务要求 - 直接连接传感器：
高达 14 位的分辨率和不同的输入范围允许在没有附加放大器的情况下连接传感器 - 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。
Design
信号模块具有与基本设备相同的设计特点。
- 安装在 DIN 导轨上：
模块安装在右侧 CPU 旁边的导轨上，相互电气、机械地连接，并且通过滑块机构连接到 CPU。 - 直接安装：
水平或垂直安装在 DIN 导轨上或使用集成插片直接安装在控制柜中。
Functions
SM 1231 模拟量输入信号模块将过程中的模拟信号转换为数字信号，以供 SIMATIC S7-1200 进行内部处理。
