ABB RED670 1MRK004810-KG Relion 670 Series

The ABB RED670 1MRK004810-KG, also cataloged as the RED670 Protection Module, operates as a dedicated hardware component for phase-segregated line differential protection within high-voltage transmission networks.

Hardware Specifications

Industrial Control & Backplane Communication Properties

As a specialized Intelligent Electronic Device (IED) within ABB Relion 670 automation platforms, the RED670 1MRK004810-KG executes high-speed signal processing and network routing:

• Profinet / EtherNet/IP Deterministic Networks: Communicates across substation Ethernet architectures using IEC 61850-8-1 protocols, publishing high-speed GOOSE messages for dynamic inter-relay interlocking and SCADA supervision.
• Backplane Bus Communication Velocity: High-speed internal bus processing compares current sample vectors at microsecond intervals between local and remote line terminals for instant, zero-latency differential evaluation.
• Firmware Flash Compatibility: Non-volatile internal memory stores protective configuration parameters and tripping logic definitions, maintaining system operational stability across controller software management cycles.

Frequently Asked Questions

Q: What tripping logic modes are supported by the RED670 1MRK004810-KG module?

A: The module supports both 1-Phase and 3-Phase tripping logic to enable selective fault clearing on high-voltage transmission lines.

Q: What primary communication protocols are natively integrated into the hardware stack?

A: The unit natively supports IEC 61850-8-1, GOOSE messaging, and standard SCADA communications.

Field Installation Guidelines

Proper mechanical and electrical execution protects the device against high electromagnetic interference in extra-high-voltage substation environments:

• Physical Mounting and Enclosure Grounding: Secure the IED chassis into a grounded 19-inch panel rack. Connect a low-impedance grounding strap directly from the chassis earth terminal to the main substation grounding grid to mitigate electromagnetic surge coupling.
• CT/VT Wiring and Shielding: Route current and voltage transformer secondary circuits through dedicated shielded cables. Ground cable shields at a single chassis entry point, and ensure CT secondary test switches are closed prior to hardware removal.
• Fiber Optic and Communication Cabling: Connect fiber optic and Ethernet communication lines to the rear ports. Maintain minimum cable bend radii to avoid signal attenuation in differential data links between remote substation ends.
