About ABB RER670 PROTECTION RELAY (ONLY DISPLAY)

ABB RER670 PROTECTION RELAY (ONLY DISPLAY)

ABBs railway application intelligent electronic device (IED), Relion RER670, is used for the protection, control and monitoring of the transmission lines and/or transformers in a two-phase 16.7, 50 and 60 Hz power system design for railway supply. It supports isolated, compensated and solidly earthed networks.

High-Resolution Display and Intuitive HMI

The RER670 relay features a vivid, high-resolution graphical LCD that supports a multilingual interface, making operation and monitoring straightforward for users of varying language backgrounds. The front panel is equipped with a keypad, push-buttons, and navigation keys, enabling efficient local control and fast access to essential settings and event records. This ensures optimal ease-of-use in on-site environments.


Comprehensive Communication Capabilities

Designed to seamlessly integrate into modern power systems, the RER670 supports a wide range of communication protocols including IEC 61850, Modbus, DNP3, and 103, as well as twice Ethernet ports. Flexible network compatibility and robust time synchronization (SNTP/NTP & IRIG-B) facilitate efficient, secure data exchange and grid-wide event coordination. This interoperability is vital for contemporary substations and grid applications.


Configurable and Reliable Protection

With freely programmable logic and settings, the RER670 allows tailored protection strategies, including overcurrent, distance, differential, voltage, and frequency options. Multiple fault event and disturbance records are stored for analysis, and the relay is compliant with high standards for EMC, insulation, shock, and vibration. Designed to operate in a wide temperature range with high mechanical durability, it offers reliability in demanding scenarios.
