概述

數字量輸入作為 SIMATIC S7-1200 CPU 的集成 I/O 的補充
可直接插入 CPU

西門子SB1221數字量輸入模塊應用領域

SB 1221 信號板數字量輸入模塊允許將控制器與過程數字信號連接。

西門子SB1221數字量輸入模塊設計

信號板直接插到每個 S7-1200-CPU 前面的支架中。

安裝：
信號板可直接插到 SIMATIC S7-1200-CPU 中，因此使用這種方法可以電氣、機械地連接到 CPU。
CPU 的安裝尺寸保持不變。
所有信號板上的端子均可拆卸，便于更換（“*接線”）。

功能

SB 1221 信號板數字量輸入/輸出模塊將過程中的外部數字信號電平轉換為 S7-1200 的內部信號電平。
