西門子SB1221數(shù)字量輸入模塊概述

數(shù)字量輸入作為 SIMATIC S7-1200 CPU 的集成 I/O 的補(bǔ)充
可直接插入 CPU

SB 1221 信號(hào)板數(shù)字量輸入模塊允許將控制器與過程數(shù)字信號(hào)連接。

設(shè)計(jì)

信號(hào)板直接插到每個(gè) S7-1200-CPU 前面的支架中。

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

功能

SB 1221 信號(hào)板數(shù)字量輸入/輸出模塊將過程中的外部數(shù)字信號(hào)電平轉(zhuǎn)換為 S7-1200 的內(nèi)部信號(hào)電平。
