Description
The ABB REC650, part number 1MRK008514-AB, is a Relion 650 Series bay control intelligent electronic device (IED) designed for protection, control, monitoring, and automation of electrical substations. ABB identifies REC650 as a dedicated bay-control solution for sub-transmission applications, particularly for switchyard equipment using single-breaker single-busbar and double-busbar arrangements.
The unit can control and monitor circuit breakers, disconnectors, and earthing switches while providing configurable protection and measurement functions. The 650 Series also provides an integrated HMI with configurable LEDs and push-button controls for local operation.
🔧 Main Function
REC650 is designed to act as the control and protection IED for an individual substation bay. It can perform switching control, interlocking, monitoring, measurement, and selected backup protection functions according to the ordered application configuration.
The exact configuration is important because the 1MRK008514-AB designation identifies the REC650 platform and ordering family, while the complete configuration code determines the installed I/O, communication interfaces, protection functions, and application-specific options. A procurement record also identifies 1MRK008514-AB as an ABB REC650 used for feeder BCPU applications.
🏭 Typical Applications
• Medium- and high-voltage substations
• Feeder bay control
• Single-busbar switchgear
• Double-busbar switchgear
• Circuit breaker control
• Disconnector and earthing-switch control
• Substation automation
• Distribution and transmission networks
• Industrial power substations

🔌 Communication & Integration
The REC650 can be integrated into modern substation automation architectures. The 650 Series supports IEC 61850-based communication, while the exact communication interfaces depend on the hardware configuration. ABB documentation also identifies PCM600 as the engineering and configuration environment for the 650 Series.
A typical installation connects the REC650 to the station communication network and to the bay’s CT/VT circuits, breaker control circuits, disconnector status signals, and other binary I/O. Remote control can be performed through the station automation system, while local switching can be performed through the IED HMI.
🛠️ Installation Notes
Before installation, verify the complete identification REC650 / 1MRK008514-AB, the complete configuration code, hardware version, auxiliary supply, communication interface, CT/VT wiring, and existing protection scheme.
Pay particular attention to breaker and disconnector interlocking. Incorrect binary I/O assignment or switching logic can prevent the bay from operating correctly.
After installation, verify IED self-diagnostics, analog measurements, binary inputs, binary outputs, communication, interlocking logic, and protection settings before returning the bay to normal operation.
⚙️ Commissioning Checklist
• Verify REC650 model and part number
• Confirm complete configuration code
• Check auxiliary power supply
• Verify CT/VT connections
• Check binary input wiring
• Verify breaker control outputs
• Test disconnector control
• Check earthing-switch status
• Configure IEC 61850 communication
• Verify interlocking logic
• Test protection functions
• Check local HMI operation
• Verify SCADA communication
• Record final settings
⚠️ Compatibility Notice
The ABB REC650 1MRK008514-AB is a dedicated substation protection and bay-control IED, not a general-purpose PLC module. The exact hardware and functions depend heavily on the complete ordering configuration.
For replacement work, match the original configuration code, hardware revision, communication interfaces, I/O arrangement, firmware, and protection application before installation. ABB’s current product information confirms REC650 as a Relion 650 Series bay-control product.
