Below is a detailed overview of its features, applications, and technical specifications:

Key Features

1. Communication Gateway
   • Acts as a bridge between ABB protection relays (e.g., REF615, REL670) and higher-level control systems (e.g., SCADA, DCS).
   • Supports industrial protocols such as IEC 61850, Modbus TCP/RTU, and DNP3 for standardized data transmission.
2. Configuration and Diagnostics
   • Compatible with ABB’s PCM600 software for relay configuration, parameter setting, and real-time diagnostics.
   • Enables firmware updates and event log retrieval for maintenance and troubleshooting.
3. Redundant Connectivity
   • Dual Ethernet ports for redundant network connections, ensuring high availability in critical power systems.
   • Optional fiber-optic interfaces for noise-immune communication in harsh environments.
4. Robust Design
   • Built to withstand industrial conditions, including temperature ranges of -25°C to +70°C and high electromagnetic interference (EMI) resistance.
   • Compact, DIN-rail-mountable housing for easy integration into control cabinets.
5. Security and Compliance
   • Implements cybersecurity features such as role-based access control and encrypted communication.
   • Complies with international standards (e.g., IEC 61850-3, IEEE 1613 for substation environments).
