Key Features & Engineering Benefits

• Integrated Bay Logic: The REC650 acts as the central brain of a switchgear bay, managing interlocking, circuit breaker control, and position monitoring in a unified platform.

• Advanced Connectivity: By supporting IEC 61850, the unit enables high-speed horizontal communication (GOOSE) for interlocking and vertical communication to the SCADA system for remote monitoring.

• Compact Footprint: Unlike larger 670 series units, the 650 series offers a more compact design, making it ideal for space-constrained panels while retaining flagship-level reliability.

• Enhanced Reliability: Continuous self-supervision ensures that any internal fault in the unit is detected and alarmed immediately, preventing "silent failures" during critical grid events.

• Real-Time Monitoring: The graphical HMI allows local technicians to perform switching operations and view measurement data without the need for an external computer.
