The ABB REC670 (part number 1MRK004814-BC) is a high-performance Bay Control IED (Intelligent Electronic Device) within the Relion 670 series. It is specifically designed for the control, monitoring, and protection of bay-level equipment in transmission and sub-transmission substations, supporting advanced automation for circuit breakers, disconnectors, and earthing switches.
Technical Functionality
The REC670 provides a unified hardware platform for comprehensive bay control, featuring built-in interlocking logic, synchrocheck, and station-wide communication capabilities. It utilizes the IEC 61850 standard to facilitate seamless horizontal (GOOSE) and vertical communication, ensuring rapid data exchange between substation components and SCADA systems.
