Product Introduction
ABB REC650 1MRK008514-AA is a bay control IED from the Relion 650 series. It is designed for sub-transmission and industrial substations where reliable apparatus control, interlocking, and local monitoring are required for single-breaker bays.
The REC650 supports control of breakers, disconnectors, and earthing switches based on the select-before-operate principle. It provides advanced interlocking, including GOOSE-based bay and station-wide interlocking, and can display status, alarms, and measurements on its local HMI. Depending on configuration, it may also include overcurrent, voltage, frequency, auto-reclose, and breaker-failure backup functions.
Some surplus listings describe this order code as a capacitor-bank protection relay or even as a PLC-style controller, but the REC650 product family is officially defined as a bay control IED. The exact protection and control functions depend on the firmware, application package, and order configuration.

Quality Control Process
- Order code verification: Confirm REC650 and 1MRK008514-AA match the original nameplate exactly.
- Visual inspection: Check front HMI, terminal blocks, communication ports, mounting hardware, and signs of overheating.
- Firmware and configuration check: Verify application package, control logic, and interlocking settings.
- Control loop test: Confirm select-before-operate, position indication, and trip/close outputs.
- Communication test: Verify IEC 61850/SCADA integration, GOOSE signals, and time synchronization if applicable.
- Packing: Anti-static protection, moisture barrier, rigid corner protection, and shock-absorbing outer carton.
Replacement Pitfall Guide
❗ Confirm the full order code. 1MRK008514-AA defines the hardware/configuration variant; other REC650 order codes may differ in I/O, firmware, and application package.
❗ Do not treat it as a generic PLC controller. Some surplus listings describe REC650 as a PLC or high-speed counting module, but REC650 is a substation bay control IED.
❗ Verify the application package. REC650 can be configured for different switchgear arrangements; wrong logic or interlocking settings may cause unsafe operation.
❗ Check GOOSE and IEC 61850 configuration. Interlocking, status exchange, and remote control depend on correct SCL/ICD files and network settings.
❗ Avoid blind replacement. Bay control IEDs are safety-critical; replacement should follow OEM procedures and site commissioning requirements.
Keep these in mind and you’ll cut 90% of rework time.
