ABB 1MRK000005-63 Dual Ethernet Communication Expansion Control Board – Relion 650 IEC 61850 GOOSE Module for REF615H / REM615 / RET615

Technical Specifications

Main Features and Advantages

The ABB 1MRK000005-63​ delivers its core value by transforming a standalone Relion 650 protection relay into a fully networked IEC 61850 intelligent electronic device (IED). Unlike generic Ethernet add-on cards, the ABB 1MRK000005-63​ is purpose-engineered to integrate seamlessly with ABB’s protection firmware, enabling native GOOSE publishing and subscription without protocol translation layers that introduce latency, single points of failure, or cybersecurity vulnerabilities.Dual independent network architecture:The defining advantage of the ABB 1MRK000005-63​ is its two physically separate Ethernet ports, which allow engineers to implement the “security zoning” principle mandated by modern substation design—Port 1 connects to the GOOSE/process bus (e.g., 192.168.1.x), while Port 2 connects to the SCADA/management network (e.g., 10.10.10.x). This separation ensures that a broadcast storm or cyber intrusion on the corporate network cannot propagate to the protection GOOSE network. The ABB 1MRK000005-63​ further supports PRP and HSR redundancy protocols, guaranteeing zero packet loss and seamless communication continuity even when a single network link fails—a non-negotiable requirement for mission-critical protection applications where communication loss could lead to protection misoperation or refusal to trip.Native IEC 61850, future-ready:The ABB 1MRK000005-63​ implements IEC 61850 Edition 2 natively, supporting GOOSE messaging, MMS reporting, and Sampled Value transmission. This eliminates the need for external gateway devices, reduces system complexity, and lowers total cost of ownership. The module is fully compatible with next-generation IED architectures, ensuring that substations upgraded today with the ABB 1MRK000005-63​ remain standards-compliant and interoperable with future equipment from ABB and other IEC 61850-conformant vendors.Plug-and-play integration:When the ABB 1MRK000005-63​ is inserted into a Relion 650 H-version relay, the host automatically recognizes the expansion card—no firmware flashing, no hardware jumpers, no compatibility guesswork. Engineers simply assign IP addresses, define GOOSE subscriptions, and configure VLAN tagging through ABB PCM600, and the ABB 1MRK000005-63​ is immediately operational. This plug-and-play behavior makes the ABB 1MRK000005-63​ the preferred solution for time-sensitive substation retrofit projects, where minimizing outage windows is critical.Industrial-grade robustness:Built to the same exacting standards as the Relion 650 relays it extends, the ABB 1MRK000005-63​ is housed in an IP20-rated enclosure and tested against the full IEC 61000-4 EMC suite, guaranteeing reliable operation in 500 kV substations where electromagnetic interference, fast transient bursts, and radiated RF energy are routine. Its -20°C to +60°C operating temperature range, 5%–95% non-condensing humidity tolerance, and < 5 W power draw ensure long-term stability inside sealed relay enclosures. Only genuine ABB-manufactured ABB 1MRK000005-63​ modules carry the certified security firmware required for GOOSE authentication—third-party clones cannot load ABB’s secure firmware and will fail GOOSE conformance testing.Cost-effective substation digitization:By adding the ABB 1MRK000005-63​ to existing Relion 650 H-version relays, utilities can uplift their protection panels to full IEC 61850 compliance without replacing expensive protection devices. A single ABB 1MRK000005-63​ module delivers decades of continued service from a protection relay that would otherwise be obsolete in a digital substation—an investment protection story that resonates strongly with asset managers and T&D engineers.
