ABB 1MRK002122-ABr05 – Original Spare/Plug-in Module for Relion Protection & Control IEDs

The ABB 1MRK002122-ABr05 is an original ABB spare/plug-in module used within the Relion protection and control platform, typically found in substation automation and industrial power systems. In many cases, this module is supplied as a like-for-like replacement or expansion unit for an existing IED, keeping your protection scheme consistent without a full panel redesign. The “AB r05” part of the code refers to the build/revision, which helps match the exact hardware generation already in service.

From my experience, customers choose this assembly when they want to minimize downtime: it slides into the designated slot, takes power from the IED backplane, and follows the host device’s environmental and firmware baseline. If you’re unsure about compatibility, we typically verify against the IED type code and the device serial/build sheet before shipment—this avoids surprises on site.

Our Order Process & Guarantees

• Warranty period: 365 days
• Delivery time: 1 week for in-stock; no more than one month at the latest
• Payment: 50% advance payment, full payment before delivery

Key Features

• Genuine ABB 1MRK part number – Ensures fit, finish and interface match with Relion-series IEDs.
• Revision AB r05 – Matches specific hardware revision levels already deployed, reducing integration risk.
• Backplane-powered – Typically powered via the host IED; no separate field power feed needed.
• Plug-in replacement – Designed for straightforward slot installation with minimal wiring changes.
• Factory-tested quality – Built to ABB’s substation-grade standards for long service life.
• Lifecycle-friendly – Helps extend the operational life of installed protection and control systems.
• Compatibility support – We can cross-check your IED type code to confirm the exact fit.

Technical Specifications

Application Fields

You might notice this model number referenced in utility and industrial MRO lists. It’s typically used in:

• Transmission and distribution substations using Relion-series IEDs
• Industrial power systems (oil & gas, mining, metals, data centers) needing fast restoration of protection functions
• Renewables interconnection and feeder protection panels where form-fit-function replacements matter
• Service retrofits to maintain installed base compatibility without changing protection settings

Advantages & Value

• Risk reduction – Like-for-like hardware matching typically avoids re-engineering or re-type testing.
• Shorter downtime – Plug-in architecture means faster return to service after a fault or failure.
• Cost control – Extends the usable life of existing panels; no need for full IED replacement in many cases.
• Assured compatibility – We cross-check against your IED type code and firmware baseline when requested.
• Spares strategy – A sensible item to keep on the shelf for critical feeders and busbar protections.

Installation & Maintenance

• Environment – Mount within a clean, ventilated switchgear or relay cabinet; follow host IED ingress and spacing rules.
• Safety – De-energize the circuit as required, apply lockout/tagout, and use ESD protection when handling modules.
• Wiring – The module interfaces via the IED backplane; field wiring remains on terminal blocks of the host device.
• Commissioning – Back up settings, verify firmware alignment, and run a point-to-point I/O or comms check after installation.
• Routine care – Periodic cabinet dust removal, connector inspection, and, if applicable, keep firmware in step with the IED baseline.

Quality & Certifications

• Manufactured under ABB’s quality system (ISO 9001)
• Conformity typically aligned with CE and RoHS for substation equipment
• Many Relion variants carry additional regional approvals (e.g., UL/CSA); confirm per exact build code
• Warranty: 365 days (backed by our stated guarantee and standard RMA procedure)

Note: ABB uses 1MRK codes as precise material numbers. Because 1MRK002122-ABr05 denotes a specific build, the exact I/O or communication function should be confirmed against your IED type code and the relay’s order sheet. Share a photo of the device label or the existing module code and we’ll verify before you place the order.
