Description
Product Overview
The ABB REC650 1MRK008514-AA is a Relion® 650-series intelligent electronic device (IED) designed for bay-level control, protection, measurement, and supervision in electrical substations. The REC650 platform is primarily intended for apparatus control of a single circuit breaker in single- and double-busbar switchgear arrangements. It combines configurable control logic, interlocking, local HMI, remote SCADA operation, synchronization functions, and disturbance recording in a type-tested application package.
The REC650 1MRK008514-AA is especially valuable in substations where reliable control of circuit breakers and disconnectors must be coordinated with the station automation system. Its select-before-execute control philosophy helps prevent incorrect switching operations, while synchronism-check and synchronizing functions support safe breaker closing. The ABB REC650 1MRK008514-AA can communicate with higher-level control systems through supported substation protocols and is designed around the IEC 61850-based Relion architecture.
In practical power-automation installations, the REC650 1MRK008514-AA acts as the intelligent control layer between primary switchgear and the substation control system. It is suitable for new digital substations as well as modernization of existing installations requiring dependable bay control, interlocking, status acquisition, measurement, and post-event analysis.

The 1MRK008514-AA ordering designation should be retained when sourcing a replacement because REC650 variants can differ in application package, I/O, communication, power supply, and hardware configuration. Available documentation specifically identifies the AA version as an application package for single breaker in a double-busbar arrangement (A02).
Main Features and Advantages
Dedicated bay-control architecture
The REC650 1MRK008514-AA is optimized for controlling a complete substation bay rather than functioning as a simple standalone relay. It can coordinate breaker and disconnector commands, collect switchgear status, and provide bay information to the station-level automation system.
Double-busbar single-breaker application
The AA configuration is associated with the A02 application for a single circuit breaker in a double-busbar arrangement. This is particularly useful where the bay must be connected to different bus sections and reliable bus-selection interlocking is required.
REC650
Secure switching and interlocking
The select-before-execute principle requires the intended switching object to be selected and verified before the command is executed. Combined with configurable interlocking logic, this helps reduce incorrect switching operations during local or remote control.
Synchronism supervision
The synchronism-check function can prevent breaker closing when voltage, frequency, or phase-angle conditions are outside configured limits. The synchronizing function can additionally command breaker closing at the appropriate point when connecting asynchronous electrical sections.
Advanced HMI and diagnostics
The 650-series IEDs provide an extended HMI with configurable indication LEDs and programmable shortcuts. Disturbance recording is also available for independent post-fault analysis, giving protection and commissioning engineers useful information when investigating abnormal events.
Digital-substation integration
As part of ABB’s Relion family, the REC650 is designed around IEC 61850 principles and can integrate with station-level automation, SCADA, protection IEDs, and other intelligent devices. This makes it suitable for distributed bay-control architectures where each bay has its own intelligent control device.
Application Fields
The ABB REC650 1MRK008514-AA is primarily used in transmission and subtransmission substations requiring intelligent control of switchgear in a double-busbar configuration. It can manage circuit-breaker and disconnector operations while enforcing configured interlocking conditions, making it suitable for critical bays where switching errors could result in equipment damage or unnecessary outages.
In utility substations, the REC650 can be deployed in line bays, transformer bays, feeder bays, and other switchgear sections where a single breaker must be controlled within a double-busbar arrangement. Remote commands can be received from SCADA or the station control level, while local operators can perform maintenance and switching operations through the IED’s HMI.
The REC650 1MRK008514-AA is also suitable for power-generation substations, including generator evacuation switchyards, plant auxiliary substations, and high-voltage interconnection facilities. Its synchronism-check and synchronizing functions are particularly useful when electrical sections need to be safely connected under controlled conditions.
For industrial power systems in oil & gas, chemical processing, metallurgy, mining, and large manufacturing plants, the REC650 can provide a dedicated intelligent bay-control layer between high-voltage switchgear and the plant’s SCADA/DCS infrastructure. Disturbance recording and event information can assist maintenance teams in analyzing switching events and abnormal operating conditions. The product is also suitable for retrofit projects where conventional bay control is being replaced with distributed IEC 61850-capable IED architecture.
