SIMATIC S7-300，数字量输入M 321，光电隔离，32DI，24 V DC，40针

概述

数字量输入
用于连接标准开关和两线制接近开关 (BERO)

应用

数字量输入模板用来实现PLC与数字量过程信号的连接。使用于连接标准开关和两线制接近开关 (BERO)。

设计

数字量输入模块具有下列机械特性：

紧凑型设计：
坚固的塑料机壳里包括：
- 绿色 LED，用于指示输入的信号状态。
- 前连接器插座，通过前门保护。
- 前门上的标签区。
- 连接器针脚分配，用于在前门内部进行配线。
安装方便：
没有插槽规则；输入地址由插槽决定。
当在 ET 200M 中与有源总线模块一起使用时，可以进行热插拔，而不会有任何反应。
方便用户接线。

具有8、16、32或64通道的模块。

功能

数字量输入模块将来自过程的外部数字信号电平转换成控制器的内部信号电平（逻辑“0”或“1”）。

多种输入电压，可支持连接不同的控制信号：

24 V DC
48 - 125 V DC
120/230 V AC

除了经济性以及易于处理的特点外，该模块还具有其他特殊功能：

可在等时模式下使用
过程和诊断报警
使用源电流或漏电流

特殊模块还可处理过程工程，例如支持 NAMUR 标准。
