The REC670 technical documentation lists the device as a pre-configured Bay Control REC670, Product Version 1.2. The same documentation specifies power-supply modules covering 24–60 VDC and 90–250 VDC nominal input ranges.
For analog protection/measurement modules, the 670 platform supports 1 A or 5 A current inputs and 110 V-class voltage inputs. Exact installed channels depend on the hardware configuration.
Product Introduction
ABB REC670 1MRK002814-AC
The ABB REC670 1MRK002814-AC is a Relion 670 Series Bay Control IED designed to supervise and control electrical switchgear at the substation-bay level. It can handle breaker and disconnector control, interlocking, status indication, measurement, event handling, and substation automation functions within a configured application.
Its practical value is not simply “control.” The REC670 can consolidate bay logic and operating information into one IED while communicating with the station automation system. That is particularly useful in substations where breaker control, interlocking, synchrocheck, measurements, and remote supervision need to be coordinated.

Application Scenarios & Field Pitfalls
Engineering Pain Point
A bay-control replacement can look deceptively easy. The wiring may fit, the display may start, and the relay may communicate with the station. Then a breaker refuses to close because an interlock, disconnector indication, synchrocheck condition, or binary-input assignment does not match the original engineering. With , configuration is part of the hardware replacement. Treating it like a generic relay is asking for commissioning problems.
Typical Applications
- Transmission Substations — Bay control for breakers, disconnectors, earth switches, interlocking, measurements, and station automation.
- Power Generation — Switchyard and generator-bay control, including breaker supervision and operating-state indication.
- Industrial Substations — Transformer and feeder bay automation in large process plants and utility distribution systems.
- High-Voltage Switchgear — Bus-coupler, bus-section, feeder, transformer, and capacitor-bank bay control applications.
Technical Pitfalls to Avoid
- Do not confuse with a dedicated protection relay.
‘s primary role is bay control and automation. It can contain protection-related functions depending on configuration, but its engineering purpose is broader than a simple overcurrent relay. - Verify the exact hardware configuration.
The platform uses modular analog and binary I/O arrangements. The complete product code and installed hardware determine what signals are physically available. The 1MRK002814-AC designation should be checked against the nameplate and project documentation. - Check auxiliary power before installation.
power-supply modules are available for different DC voltage ranges. The technical documentation lists 24–60 VDC and 90–250 VDC variants. Do not connect a plant’s 24 VDC supply to a unit configured for a high-voltage DC power module. - Back up the PCM600 project.
Save the complete IED configuration, application logic, communication settings, I/O mapping, and parameter set before removing the original device. Recreating bay logic manually during an outage is avoidable. - Verify interlocking logic point by point.
Breaker-close permissives, disconnector positions, earth-switch status, local/remote selection, and mechanical interlocks must correspond to the actual switchgear. A single inverted binary input can block an otherwise healthy bay. - Check synchrocheck configuration where applicable.
If the controls breaker closing across energized sections, verify voltage inputs, phase-angle settings, frequency difference, voltage difference, and dead-line/dead-bus logic. Do not assume these settings transfer automatically between projects. - Do not assume identical communication hardware.
IEC 61850 capabilities exist within the platform, but the physical communication interfaces and configured protocols depend on the installed hardware. Confirm the station-bus architecture before ordering a replacement. - Test the complete operating sequence.
A successful communication test is not enough. Test local control, remote control, interlocking, breaker indication, disconnector indication, alarms, trip/close outputs, and station-control-system feedback. - Respect the CT/VT circuits.
Where analog measurement inputs are used, verify CT ratios, VT ratios, polarity, phase sequence, and wiring. An incorrect phase assignment can produce believable but wrong measurements.
