Input/output: 8 digital inputs and 8 digital outputs, supporting flexible configuration.

Communication interface: ABB REF615 HCFFAEAGABC2BAA11E supports IEC 61850 (including process bus), Modbus, DNP3, IEC 60870-5-103 and other protocols, with strong compatibility.

Processing performance: equipped with 80C196KB CPU, 14-bit A/D converter, 24 analog inputs, ensuring high-precision measurement.

Protection level: IP40, suitable for general industrial environments.

Comprehensive Feeder Protection: Single device covers all main feeder protection needs—phase, earth, directional, thermal, and sequence-of-events

High-Speed Ethernet with IEC 61850: Peer-to-peer GOOSE messaging and sampled-values support for fast interlocking and automation.

Advanced Fault Recording: High-resolution disturbance and waveform capture aids in post-fault analysis and compliance reporting.

Built-In Automation: Programmable logic (IEC 61131-3 function blocks) lets you embed basic control schemes—transfer trips, interlocks, auto-reclose—directly in the relay.

Flexible HMI & Visualization: On-screen mimic diagrams and configurable numerical and bar-graph displays simplify local troubleshooting.

Secure Communications: Support for secure authentication, built-in firewall, and VPN tunneling protects critical feeder control.

Arc-Flash Detection & Mitigation: Optional arc-flash detection card enables ultra-fast trip on high-energy faults in switchgear.

Easy Configuration & Maintenance: DIGSI 5 software for intuitive setting management, firmware updates, and event analysis via USB or network.

Used for the power system of the fracturing pump group, connecting 200+ sensors through Modbus TCP/IP, achieving 5ms fault response, and accumulating 50,000 hours of trouble-free operation.

Deployed in a 150MW photovoltaic cluster, achieving distributed power fluctuation coordination through IEC 61850 GOOSE, and processing an average of 10TB of data per day.

Control of reverse osmosis high-pressure pump groups, integrated arc protection module, shortening the arc fault removal time to ≤7ms
