The product guide describes it as a pre-configured Bay Control IED, Product Version 1.1. The same guide covers modular binary input/output, transformer input, power-supply, and communication hardware.
The exact I/O count should not be inferred from the model number. The platform uses selectable hardware modules, so the installed unit must be checked against its complete configuration and terminal documentation.
Product Introduction
ABB 1MRK002814-AB
The ABB 1MRK002814-AB is a Relion 670 Series Bay Control IED, Product Version 1.1, designed for control, protection, monitoring, and automation of electrical substation bays. Typical functions include circuit-breaker and disconnector control, interlocking, measurements, status supervision, and communication with higher-level substation automation systems.
Its main engineering value is centralized bay-level logic. Instead of distributing breaker commands, interlocking conditions, status handling, and measurement functions across several independent devices, the can consolidate these functions within a configured IED. The actual capability depends on the installed hardware and application configuration.

Application Scenarios & Field Pitfalls
Engineering Pain Point
A bay-control IED can cause a difficult outage even when the hardware itself is healthy. The breaker may refuse to close because one disconnector indication is missing. Remote control may fail because an IEC 61850 data object was mapped differently. A replacement that powers up correctly can still be unusable if its application configuration does not match the original bay.
Typical Applications
- Transmission Substations — Bay control for breakers, disconnectors, grounding switches, interlocking, and station-level automation.
- Power Generation — Generator and transformer bay control in switchyards, including breaker operation and equipment-status supervision.
- Industrial Substations — MV/HV feeder and transformer bays serving refineries, chemical plants, and other continuous-process facilities.
- Utility Distribution — Feeder and bus-section control where local automation and remote SCADA operation are required.
Technical Pitfalls to Avoid
- Do not confuse the with a simple protection relay.
Its primary role is bay control and automation. Protection functions may be included depending on the configured application, but the device should be engineered as a complete bay-level IED. - Verify the exact hardware configuration.
The uses modular hardware. Analog input, binary input/output, communication, and power-supply arrangements can vary. The 1MRK002814-AB designation identifies the product/version family, but it does not replace the project-specific configuration record. - Back up the PCM600 configuration before replacement.
Preserve the complete IED configuration, application logic, communication settings, I/O assignments, and parameter values. Recreating interlocking logic during a live shutdown is poor engineering practice. - Check breaker and disconnector logic point by point.
Local/remote selection, breaker position, disconnector position, earth-switch status, electrical interlocks, and close permissives all need to agree with the actual switchgear. - Verify the auxiliary power module.
Do not assume every uses the same DC input range. The 670 platform uses different power-supply modules. Match the replacement to the installed power architecture. - Do not assume identical communication hardware.
IEC 61850 capability exists within the Relion 670 architecture, but the actual communication hardware and configuration depend on the selected modules. ABB documentation also shows used in IEC 61850 substation architectures. - Check CT/VT configuration where measurement inputs are installed.
Current-input modules can be configured for 1 A or 5 A nominal CT circuits. Verify the actual CT secondary rating, polarity, phase assignment, and terminal wiring before energizing the replacement. - Test the complete bay sequence.
A successful HMI or communication test is not sufficient. Test local control, remote control, interlocking, breaker indication, disconnector indication, alarms, trip/close outputs, and station-control feedback.
