Key Features & Engineering Advantages
Advanced Bay Interlocking:The REC670 provides software-based interlocking that prevents dangerous switching operations, such as opening a disconnector under load, by verifying the status of all relevant equipment in real-time.
High Availability Communication:By supportingIEC 61850, the unit enables high-speed horizontal communication (GOOSE) for station-wide interlocking and vertical communication to SCADA systems for remote operation.
Modular Hardware Design:The "670 platform" allows for the addition or replacement of I/O modules, making the REC670 adaptable for future expansions or changes in substation layout.
Integrated Monitoring:It goes beyond simple control by acting as a high-precision monitoring tool, tracking breaker wear, gas pressure (via digital inputs), and electrical parameters to assist in predictive maintenance.
Cyber Security:Includes robust security features such as role-based access control and encrypted communication to safeguard critical grid infrastructure against unauthorized access.
