- 安装在 DIN 导轨上:
将模块卡装到 CPU 右侧的导轨上,互相连接以后再通过集成背板总线连接到 CPU 12xx。 - 直接安装:
通过钻孔,可将模块直接螺栓安装到墙壁上。在易受剧烈振动的场合建议采用这种安装方式。 - 热电偶:
可以使用 4 种类型的 J、K、T、E、R、S 和 N 型热电偶。无需放大器即可直接连接到模块上。 - 安装位置:
为了实现**的测量和重复精度,应将热电偶模块安装在温度变化较小的位置。

- 温度记录方便,**度高
- 可以使用 7 种通用型号的热电偶
- 另外,也可测量低电平模拟信号 (±80 mV)。
- 对现有装置改装非常容易
通过 SM 1231 热电偶模块,使用技术成熟的热电偶,可高精度的对温度进行测量。另外,也可记录低电平模拟信号 ±80 mV。热电偶模块 SM 1231 可与 S7-1200 系列的 CPU 组合使用。
不同的量程:
J、K、T、E、R、S 和 N 型热电偶;模拟量信号记录 ±80mV。
开路检查。
冷端补偿:
避免了热电偶和模之间连接处由于接触电压导致的故障;记录模拟信号 (±80 mV) 时将自动禁止补偿。
温度单位:
温度测量单位可以用 ℃ 或 ?。
