西门子SB1231热电偶信号板
- 温度记录方便,**度高
- 1 点输入,16 位精度,
- 可以使用通用热电偶
- 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
- 可直接插入 CPU
西门子SB1231热电偶信号板
信号板直接插到每个 S7-1200-CPU 前面的支架中。
- 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。
- 所有信号板上的端子均可拆卸,便于更换(“固定接线”)。
- 不同的测量范围:
J 型和 K 型热电偶;模拟量信号记录 ±80 mV。 - 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。 - 温度范围:
可显示℃或?温度。
