Product Overview

The ABB REC670 (Part Number 1MRK004814-AC) belongs to the premium Relion 670 series and serves as a highly sophisticated Intelligent Electronic Device (IED) for modern digital substation automation. This Swiss-manufactured unit controls and supervises primary electrical equipment within transmission and distribution networks up to 550 kV. It manages circuit breakers, disconnectors, and earthing switches using software-defined interlocking logic rather than legacy hard-wired systems.

We guarantee this product is 100% Brand New, original factory equipment, and ready for deployment in your high-voltage grid automation architecture.

Engineering Advantages

Replaces Complex Hard-Wired Frameworks: The unit replaces heavy copper control wiring looms with high-speed digital communications over fiber optic networks. This transition reduces physical footprint inside control houses and drastically simplifies point-to-point electrical tracing during commissioning.
Secures High-Voltage Switching Sequences: Internal software-defined interlocking mechanisms enforce strict control sequences for primary disconnectors and earthing switches. This logic prevents hazardous out-of-sequence operations, protecting substation personnel and high-value transformer assets.
Enables Real-Time Interoperability: Full compliance with IEC 61850 Edition 1 and Edition 2 allows the IED to exchange peer-to-peer GOOSE (Generic Object Oriented Substation Events) messages and Sampled Values smoothly. This standard ensuring seamless speed matching with third-party protection units.
Defies Intense Electromagnetic Interference (EMI): The ruggedized metal 6U chassis contains specialized shielding that neutralizes extreme electromagnetic fields, radio frequency interference, and high-voltage switching surges common in high-voltage utility yards.

FAQs

Can the 1MRK004814-AC handle time synchronization across a distributed network without an external master clock?

Yes. This REC670 configuration integrates Precision Time Protocol (IEEE 1588 PTP) and SNTP protocols. It synchronizes down to microsecond thresholds directly over the station bus, though you can also attach an external GPS or IRIG-B antenna source directly to the chassis receiver ports.
What are the mounting prerequisites for securing the IP54 front panel rating?

To maintain an IP54 ingress protection rating on the front face, you must use the standard flush-mounting kit with the supplied rubber sealing gasket against a clean, flat 19-inch cutout panel surface. Ensure all fixing screws match torque specifications to maintain compression along the gasket line.
Does this unit support dual-redundant network paths?

Yes. The dual 100BASE-FX or 10/100BASE-TX Ethernet interfaces allow the IED to connect to parallel LAN segments. This configuration supports zero-delay recovery protocols like PRP (Parallel Redundancy Protocol) and HSR (High-availability Seamless Redundancy) to keep data flowing if a single fiber run breaks.
