Description
ABB REC670 (1MRK002814-AC) – High‑performance bay control IED for substation automation
The ABB REC670 is part of the Relion 670 series, built for precise bay control, interlocking, and IEC 61850-based substation automation. The order code 1MRK002814-AC denotes a specific hardware and option combination within the REC670 family—typically configured for robust switchgear control, fast GOOSE messaging, and reliable synchrocheck. One thing I appreciate is how it consolidates bay control logic, measurements, and communications into a single, serviceable unit that fits well in modern and retrofit cubicles.
Company’s Order Placement Process and Guarantees
- Warranty: 365 days
- Delivery time: 1 week for in-stock items; no more than one month at the latest
- Payment terms: 50% advance payment; full payment prior to delivery
- Express options: FedEx, UPS, DHL
Key Features
- Bay control and interlocking – Ready-made logic templates with flexible customization to enforce safe switching sequences.
- Synchrocheck – Voltage inputs allow closing checks across sources, typically reducing mis-operations during energization.
- IEC 61850 Ed.2 with GOOSE – Fast peer-to-peer signaling and MMS for SCADA; PRP/HSR redundancy on dual Ethernet ports is commonly available.
- Rich I/O – Galvanically isolated binary inputs, high-duty relay outputs, and double-point indication handling for disconnectors/earthing switches.
- Event and disturbance records – Millisecond time-stamped SOE and COMTRADE disturbance files streamline fault analysis.
- Engineering via ABB PCM600 – From my experience, configuration and logic edits are straightforward, which shortens FAT/SAT cycles.
- Time synchronization – SNTP and IRIG-B help keep records aligned across bays and substations.
- Modular hardware – Flexible slotting to match feeder, transformer bay, or bus-tie applications; spares stocking becomes simpler.
Technical Specifications
| Brand / Model | ABB REC670 – Order code 1MRK002814-AC |
| HS Code | 853710 (commonly used for protection & control IEDs; final classification may vary by country) |

| Operating Temperature | -25°C to +55°C operation (storage typically up to +70°C) |
| Signal Input/Output Types | Binary inputs (typ. 24–250 V DC), relay outputs (NO/NC), double-point indications; VT inputs for synchrocheck/voltage measurements |
| Communication Interfaces | IEC 61850 MMS/GOOSE; dual Ethernet with PRP/HSR in many cases; SNTP/IRIG-B; optional IEC 60870-5-104, DNP3, Modbus TCP |
| Installation Method | Panel/flush mounting in switchgear cabinets; rear terminal wiring; suitable for 19-inch subrack arrangements |
Application Fields
- Transmission and distribution bays (breaker, disconnector, earthing switch control with interlocking)
- Bus-tie and coupler bays requiring dependable synchrocheck prior to closing
- Industrial substations—steel, mining, oil & gas—where compact bay control simplifies retrofit projects
- Renewables and IPP substations integrating IEC 61850 peer-to-peer schemes without hardwiring
Advantages & Value
- Reliability – Proven Relion 670 platform, event-stable firmware, and fast failover with PRP/HSR reduce single points of failure.
- Compatibility – Multi-protocol support trims gateway needs and eases SCADA integration in mixed fleets.
- Lifecycle cost – Modular I/O keeps spares lean and helps standardize across bay types, which in many cases lowers total cost of ownership.
- Serviceability – Front HMI, clear SOE, and COMTRADE exports shorten fault-finding and outage times.
You might notice that the REC670 scales well from a single feeder to a full yard. A utility client shared that after migrating to IEC 61850 GOOSE on REC670, they eliminated a surprising amount of copper interlocking wiring and cut commissioning hours dramatically.
Installation & Maintenance
- Cabinet & mounting – Install in a clean, dry switchgear cubicle; allow front access and rear wiring space; maintain ventilation around the unit.
- Wiring – Use shielded twisted pair for IRIG-B/time sync and Ethernet as per ABB guidelines; keep VT and control wiring segregated; confirm interlocking logic with a formal test plan.
- Grounding – Bond the IED chassis to the station earth; observe EMC practices to minimize induced noise.
- Commissioning – Validate GOOSE datasets, time sync (SNTP or IRIG-B), and synchrocheck thresholds; save final PCM600 project backups.
- Routine maintenance – Periodic logic and settings review, clean front filters/vents, check time sync status, and export SOE/disturbance logs. Firmware updates can be planned during outages to keep functions aligned with fleet standards.
Quality & Certifications
- CE marked; RoHS compliant
- Designed and type-tested to relevant IEC standards for protective/measurement IEDs (e.g., IEC 60255 series, EMC/EMI)
- IEC 61850 conformance for station bus; COMTRADE disturbance records
- Manufacturer’s warranty: 12 months (as listed above)
Supporting Components (commonly paired)
- ABB RTXP test switches (for safe secondary injection and isolation during maintenance)
- IRIG-B time source or GPS clock for precise station-wide time alignment
- Industrial Ethernet switches with PRP/HSR support for network redundancy
Note: REC670 configurations are highly option-dependent. The code 1MRK002814-AC identifies a specific build; if you share your bay scheme (breaker/disconnector count, VT availability, protocol needs), I can validate I/O cards, power module range, and firmware package before shipment.
