☆型号:DI821 3BSE008550R1 交流/直流数字输入模块 8 个数字输入
【产品详情】
DI821 是用于 S800 I/O 的 8 通道 230 V 交流/直流数字输入模块。该模块有 8 个数字输入。交流输入电压范围为 164 至 264 V,交流 230 V 时输入电流为 11 mA,直流输入电压范围为 175 至 275 V,220 V 直流时输入电流为 1.6 mA。输入是单独隔离的。
每个输入通道都由限流元件、EMC保护元件、输入状态指示LED、光学隔离栅和模拟滤波器(6 ms)组成。
通道 1 可用作通道 2 - 4 的电压监控输入,通道 8 可用作通道 5 - 7 的电压监控输入。如果连接到通道 1 或 8 的电压消失,则错误输入被激活,警告 LED 亮起。错误信号可以从 ModuleBus 读取。

【英文介绍】
The DI821 is an 8-channel 230 V AC/DC digital input module for the S800 I/O. The module has 8 numeric inputs. The AC input voltage range is 164 to 264 V, the input current is 11 mA at 230 V, the DC input voltage range is 175 to 275 V, and the input current is 1.6 mA at 220 V DC. The input is isolated.
Each input channel consists of a current limiting element, an EMC protection element, an input status indicator LED, an optical isolation gate, and an analog filter (6 ms).
Channel 1 can be used as a voltage monitoring input for channels 2-4, and channel 8 can be used as a voltage monitoring input for channels 5-7. If the voltage connected to channel 1 or 8 disappears, the error input is activated and the warning LED lights up. The error signal can be read from the ModuleBus.
Characteristics and advantages
8 channels for 120 V AC/DC input
Separate, isolated channels
Voltage monitoring of field input power
Input status light
Signal filtering
