ABB REC650 | 1MRK008514-AB | Relion 650 Bay Control IED

Product Overview

The REC650 (1MRK008514-AB) is a high-performance Intelligent Electronic Device (IED) belonging to ABB’s Relion® 650 series. Specifically engineered for bay control, monitoring, and protection in medium- and high-voltage substations, it serves as a central intelligence unit for switchgear management. This module supports diverse substation topologies including single busbar, double busbar, and breaker-and-a-half schemes. By integrating OPC technology and IEC 61850 standards, the REC650 enables real-time data visualization and deterministic control over network components, bridging the gap between primary equipment and substation automation systems.
