ABB DO810 数字量输出模块

该模块有 16 个数字输出。输出电压范围为 10 至 30 伏，最大连续输出电流为 0.5 A。输出具有短路、过压和过温保护。输出分为两个独立隔离的组，每组有八个输出通道和一个电压监控输入。每个输出通道由短路和过热保护高边驱动器、EMC保护元件、感性负载抑制、输出状态指示LED和光隔离栅组成。

如果电压消失，过程电压监控输入会发出通道错误信号。错误信号可以通过模块总线读取。输出具有电流限制和过热保护。如果输出过载，输出电流将受到限制。

This module has 16 digital outputs. The output voltage range is 10 to 30 volts, and the maximum continuous output current is 0.5 A. The output has short-circuit, overvoltage, and overtemperature protection. The output is divided into two independently isolated groups, each with eight output channels and one voltage monitoring input. Each output channel is composed of short circuit and overheat protection high side drivers, EMC protection components, inductive load suppression, output status indicator LEDs, and optical isolation barriers.

If the voltage disappears, the process voltage monitoring input will issue a channel error signal. The error signal can be read through the module bus. The output has current limitation and overheating protection. If the output is overloaded, the output current will be limited.
