1MRK008514-AB REC650 ABB Relion 650 Bay Control IED

Product Description

1MRK008514-AB REC650 is ABB Relion® 650 series bay control intelligent electronic device (IED), dedicated for bay-level control, supervision and backup protection in power substations. This panel-mounted IED integrates electrical measurement, apparatus control, interlocking, fault recording and communication functions. It manages circuit breakers, disconnectors and earthing switches for single busbar, double busbar and other switchgear configurations. The suffix AB represents the specific hardware and firmware configuration variant. It complies with IEC 61850, IEC 60255 standards and supports GOOSE messaging for fast substation automation communication.
