ABB RED521 1MRK002003-BA 数字差动保护终端 成都阳光熹禾

产品细节说明:RED521 1MRK002003-BA ABB 数字差动保护终端

1. 功能特点：该模块具备数据采集与记录功能，能以表格形式显示从各种工业设备中收集的数据，并允许用户根据指定间隔刷新显示内容。此外，模块还提供触发命令选项、安全功能，具备Web服务器功能，并允许用户根据数据值自动改变单元格颜色，作为一个报警系统 。
2. 差动保护端子特性：RED521 1MRK002003-BA的CT要求非常低，允许CT电路与其他继电器共享以节省成本。最多可以将18个电流互感器直接连接到端子，简化了工程设计，因为只需要两个操作设置而无需插入辅助CT。CT比率作为前置HMI的主要值输入，缩短了调试和安装时间 。
3. 性能：RED521 1MRK002003-BA在所有内部故障下的极短操作时间通常为10-15ms，无论连接的馈线数量如何，同时即使发生严重的CT饱和，终端也能保持对外部故障的完全稳定性 。

Product Details: RED521 1MRK002003-BA ABB Digital Differential Protection Terminal
Functional features: This module has data collection and recording functions, which can display data collected from various industrial equipment in table form, and allow users to refresh the display content at specified intervals. In addition, the module also provides trigger command options, security features, web server functionality, and allows users to automatically change cell colors based on data values as an alarm system.
Differential protection terminal characteristics: The CT requirements for RED521 1MRK002003-BA are very low, allowing the CT circuit to be shared with other relays to save costs. Up to 18 current transformers can be directly connected to the terminals, simplifying engineering design as only two operation settings are required without the need to insert an auxiliary CT. The CT ratio serves as the main input value for the front-end HMI, reducing debugging and installation time.
Performance: RED521 1MRK002003-BA typically has a very short operating time of 10-15ms under all internal faults, regardless of the number of connected feeders. Even in the event of severe CT saturation, the terminal can maintain complete stability against external faults.
