- SIMATIC S7-1200 的模拟量输出
- 可直接插入到 CPU
Area of application
SB 1232 模拟量输出信号板允许使用模拟量输出。
这为用户提供了下列优势：
- 最佳适应性：
在空间有限的情况下，或只需要少数附加输入/输出的情况下，可以使用信号板。通过信号板可以对 S7-1200 CPU 进行模块化扩展。这不会增加控制器所需的安装空间。
- 传感器和执行器的直接连接
高达 14 位的分辨率和不同的输出范围允许在没有附加放大器的情况下连接执行器。
- 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
信号板直接插到每个 S7-1200 CPU 前面的插座中。
- 安装：
信号板直接插到 SIMATIC S7-1200 CPU 中，因此可以电气、机械地连接到 CPU。
- CPU 的安装尺寸保持不变。
- 由于所有信号板均配备可拆卸的连接端子（“独立接线”），所以更换方便。
Functions
SB 1232 模拟量输出信号板将 S7-1200 的数字信号转换为过程所需的模拟信号。
