Description
The ABB REC670 (order code 1MRK002814-AB) is an Intelligent Electronic Device (IED) from the ABB Relion 670 series, designed for comprehensive bay control, monitoring, and interlocking in medium- to extra-high-voltage substations.
The REC670 controls and supervises primary apparatus—such as circuit breakers, disconnectors, and earthing switches—and integrates synchrocheck, energizing check, auto-reclosing, and flexible command handling directly into IEC 61850 substation automation architectures.

Core Features & Operating Capabilities
- Apparatus Control & Interlocking: Controls up to tens of switching devices per bay with built-in software interlocking schemes to prevent unsafe or out-of-sequence switching operations.
- Synchrocheck & Energizing Check: Performs high-speed phase angle, voltage magnitude, and frequency differential calculations to safely supervise manual or automatic circuit breaker closing.
- Native IEC 61850 Integration: Communicates over redundant optical Ethernet rings using IEC 61850 GOOSE messaging for high-speed bay-to-bay inter-tripping and interlocking.
- PCM600 Software Configuration: Fully programmed, engineered, and commissioned using ABB’s PCM600 (Protection and Control IED Manager) software suite.
- Disturbance & Event Reporting: Features built-in fault location, event logging (up to 1,000 events with 1 ms resolution), and disturbance recording capability for post-fault analysis.
