ABB RXIIK 4 1MRK001643-AA
Product Introduction
The ABB RXIIK 4 1MRK001643-AA is a high-availability communication interface module designed for ABB’s Relion® 670 series protection relays. Serving as the cyber-secure gateway for modern substations, this module enables seamless integration of protection relays with IEC 61850-compliant control systems while providing robust cybersecurity and deterministic data exchange. Engineered for critical infrastructure, the ABB RXIIK 4 1MRK001643-AA processes GOOSE messages, MMS reporting, and legacy protocol conversion with sub-millisecond latency.
As part of ABB’s Relion product line, this module transforms REF615 and REG670 relays into networked intelligent electronic devices (IEDs). Its core function is to bridge protection logic with station bus networks while maintaining the stringent timing requirements of grid automation schemes. The ABB RXIIK 4 1MRK001643-AA features hardware-accelerated encryption and complies with IEC 62443 security standards, making it essential for smart grid applications where data integrity and availability are paramount.
Core Advantages and Technical Highlights
Deterministic Protocol Handling: The ABB RXIIK 4 1MRK001643-AA processes GOOSE messages with <500 μs latency, enabling ultra-fast busbar protection schemes. Hardware-based protocol offloading ensures zero packet loss during grid disturbances.
Multi-Layer Cybersecurity: Implements MACsec (IEEE 802.1AE) encryption for all station bus traffic. Secure boot with TPM 2.0 validation prevents firmware tampering. Role-based access control (RBAC) enforces IEC 62351 authentication standards.
Dual-Precision Timing: Concurrent support for IRIG-B DC and PTP (Class B) enables microsecond-accurate time stamping. Automatic fallback maintains synchronization during GNSS outages – critical for fault location.
Hybrid Network Topologies: Simultaneous operation of copper (RJ45) and fiber (SFP) ports enables ring/mesh architectures. Built-in PRP/HSR redundancy ensures zero recovery time during switch failures.
Environmental Hardening: -40°C cold-start capability with conformal-coated PCBs resisting 100% humidity. Vibration tolerance (3g @ 10-150Hz) suits mobile substations.
Legacy Protocol Conversion: Native DNP3.0 over TCP/IP and Modbus TCP support eliminates protocol gateways. Data mapping preserves semantic meaning between IEC 61850 and legacy SCADA points.
Typical Application Scenarios
Digital Substation Automation: Integrates REG670 relays into IEC 61850-9-2LE process bus architectures. GOOSE messaging enables <10ms bus differential protection.
Renewable Integration: Coordinates solar/wind farm protection relays via DNP3.0. Fiber optic ports prevent lightning-induced damage in exposed locations.
Railway Traction Power: Synchronizes feeder protection across 25kV substations. PTP timing ensures accurate fault location on catenary lines.
Offshore Wind HVDC: Implements cyber-secure communication between platform relays and shore control. DNV-GL certification validates marine environment performance.
Industrial Microgrids: Bridges legacy Modbus devices with modern SCADA via IEC 61850 MMS. Dual-power inputs maintain operation during source switching.
