ABB RED670 1MRK004810-CC Relion 670 Series Protection Relays

The ABB RED670 1MRK004810-CC, also cataloged as the RED670 Protection Module, operates as a dedicated hardware component for multi-functional feeder protection and line differential monitoring within IEC 61850 substation architectures.

Hardware Specifications

Industrial Control & Backplane Communication Properties

As a core Intelligent Electronic Device (IED) within ABB Relion 670 automation architectures, the RED670 1MRK004810-CC incorporates dedicated processing and network characteristics:

• Profinet / EtherNet/IP Deterministic Networks: Supports IEC 61850 Edition 2 fast ethernet communication services, publishing high-speed GOOSE messages and receiving Sampled Values (SV) across deterministic station and process bus topologies.
• Backplane Bus Communication Velocity: Internal high-performance bus architecture routes 4 kHz analog sampling data to the primary processor, allowing protection algorithms to execute tripping decisions with millisecond-level response times.
• Firmware Flash Compatibility: Internal flash memory supports field configuration updates via the PCM600 tool, preserving protective parameter matrices and disturbance records during system firmware management.

Frequently Asked Questions

Q: What communication interfaces and protocols are supported by the RED670 1MRK004810-CC module?

A: The module supports IEC 61850 Edition 2 (MMS, GOOSE, Sampled Values), Modbus TCP, and DNP3.0 over industrial Ethernet ports.

Q: What power supply range does the universal input card accept?

A: The integrated universal power supply operates across a voltage input range of 24 to 250 VDC or 100/110/230 VAC.

Field Installation Guidelines

Proper mechanical mounting and signal wiring procedures preserve protection reliability and electrical isolation:

• Panel Mounting and Earth Grounding: Secure the 4U enclosure into a standard 19-inch relay cabinet frame or cutout. Connect a heavy-gauge copper grounding strap from the chassis grounding stud directly to the substation earth bus bar to ensure electromagnetic noise suppression.
• CT/VT Terminal Wiring: Wire current and voltage transformer secondary circuits to the designated compression terminal blocks. Verify shorting switches are engaged before servicing current transformer loops to prevent open-circuit high-voltage hazards.
• Ethernet Communication Shielding: Route shielded twisted-pair (STP) or fiber optic Ethernet cables away from high-voltage primary conductors and switching contactors. Connect cable metal shielding to functional earth at the cabinet entry point.
