The ABB 1MRK002246-BD is a specialized hardware component designed for the Relion 670 and 650 series of Intelligent Electronic Devices (IEDs). This module functions as a communication interface, enabling the protection relay to exchange data across high-speed industrial networks within a digital substation.
Technical Specifications
- Series Compatibility: Specifically engineered for ABB Relion 670/650 series protection and control systems.
- Module Type: Communication/Optical Interface.
- Protocol Support: Optimized for IEC 61850-8-1 and IEC 61850-9-2LE process bus communication, supporting Station Bus and Process Bus architectures.
- Connectivity: Typically features fiber optic ports (LC or ST connectors) to ensure high-speed data transfer and total immunity to electromagnetic interference (EMI).



Primary Functions
- Substation Automation: Facilitates the transmission of GOOSE (Generic Object Oriented Substation Event) messages and Sampled Values for real-time protection.
- Network Integration: Connects the IED to the Station Bus, allowing for remote monitoring, configuration, and data logging via DCS or SCADA systems.
- Time Synchronization: Supports high-precision time protocols (such as IEEE 1588 PTP) to ensure synchronized data across the entire grid.
Applications
This module is a critical requirement in modern electrical substations, renewable energy plants, and heavy industrial power networks. It is essential for implementing distributed protection schemes and ensuring that critical fault data is communicated instantly to maintain grid stability.
