Product Description

Overview

The ABB RED670 (Part Number: 1MRK000008-MB) is a high-resolution graphical display module engineered for the Relion® 670 series IEDs. Designed for local monitoring, control, and diagnostics in high-voltage substations, this interface is optimized for line differential protection. It supports multi-terminal configurations, real-time data visualization, alarm management, and operator control, making it suitable for demanding transmission and distribution environments.

Applications

The RED670 display panel is ideal for:

• Multi-terminal overhead lines and cable networks

• Substations requiring fast and selective line differential protection

• Long-distance transmission lines where capacitive charging currents affect protection performance

• Substation automation projects with IEC 61850-compliant devices

Key Features

• High-Resolution Graphical Interface: Touchscreen with ANSI symbol support and backlit LCD navigation.

• Real-Time Monitoring: Displays voltages, currents, and line status for up to five terminals.

• Alarm and Event Management: Visual and programmable indicators for system events.

• Operator Control: Supports breaker commands, autoreclosing, and synchrocheck functions.

• Data Logging & Disturbance Recording: Captures high-resolution waveforms for post-fault analysis.

• Communication Interfaces: Internal bus with the main relay unit; supports IEC 61850, DNP3, and IEC 60870-5 protocols.

• Redundancy Support: Compatible with PRP and HSR networks for high availability.

• Compact Mounting: Front panel installation compatible with existing relay cubicles.

Technical Specifications

Performance Highlights

• Phase-Segregated Line Differential: Fast sub-cycle detection with high sensitivity for internal faults.

• Charging Current Compensation: Handles long cables and high-voltage line capacitance.

• Distance Protection Integration: Includes quadrilateral and Mho characteristics, with load encroachment and power swing detection.

• Synchronization Options: Supports GPS (IRIG-B/SNTP) or echo mode for devices without GPS.
