REX 521 馈线和电动机保护继电器设计用于在中压电力系统中进行保护、控制、测量和监控。典型的应用包括进、出馈线以及变电站保护、保护继电器配有用于常规电流和电压互感器的交流量输入端。此外，该继电器还提供含电流和电压传感器输入的硬件版本该继电器基于多处理器环境 HMI 包括一个 LCD( 液晶显示器 ) 具有不同的视图，便于本地使用，并通过指示信息通知用户。在硬件和软件解决方案中采用现代技术。

REX 521 是用于配电自动控制中变电站自动控制概念的一部分，进一步扩展了系统的功能和灵活性。

The REX 521 feeder and motor protection relay is designed for protection, control, measurement, and monitoring in medium voltage power systems. Typical applications include incoming and outgoing feeders, substation protection, and protection relays equipped with AC input terminals for conventional current and voltage transformers. In addition, the relay also provides a hardware version with current and voltage sensor inputs. The relay is based on a multiprocessor environment HMI, including an LCD (liquid crystal display) with different views for local use, and notifies users through indicator information. Adopting modern technology in hardware and software solutions.

REX 521 is a part of the concept of substation automatic control used in distribution automatic control, further expanding the functionality and flexibility of the system.
