Description
- Model / Part Number: 1MRK001967
- Brand: ABB
- Series: ABB Relion / Protection and Control Platform
- Part Type: Protection and control system hardware spare
- Core Function: Provides a hardware function within ABB’s protection and substation automation equipment; the exact function depends on the complete assembly designation associated with the 1MRK001967 number.
- Key Specs: ABB article number 1MRK001967; associated with ABB’s protection and control product ecosystem; exact electrical characteristics require equipment-level identification.
Product Introduction
A protection-system spare should never be identified solely by visual appearance. The ABB 1MRK001967 designation is an ABB article/reference number, but the number alone does not provide enough verified information to assign a specific I/O channel count, voltage range, communications interface, or processor function.
In field maintenance, that distinction matters. ABB protection hardware often uses article numbers alongside complete product names, ordering codes, hardware revisions, and assembly references. A replacement that looks identical can still have a different electrical role or revision.
For procurement, 1MRK001967 should therefore be matched against the original nameplate, complete device type, installed rack position, and ABB documentation. This is particularly important for legacy substation installations where an incorrect module can affect protection, measurement, or communications.
Procurement note: I would not assign unsupported specifications to 1MRK001967. ABB article numbers in this format can correspond to internal hardware assemblies, and a reliable product description requires the associated ABB device/model number.

Application Scenarios & Pain Points
During a substation outage, an unidentified protection-system component can become the critical path for restoring a bay. Correctly identifying 1MRK001967 before ordering avoids the risk of receiving a physically compatible but electrically incorrect board.
High-voltage substations: The component may form part of an ABB protection and control assembly where exact hardware identification is required before maintenance work.
Relay replacement projects: When an older ABB relay or protection system is being repaired, the 1MRK001967 number can help trace the original hardware assembly when combined with the complete device designation.
Legacy system maintenance: Older protection equipment can remain in service for many years. Maintaining an exact spare becomes increasingly important when original documentation and commercial availability become limited.
Engineering migration: Before replacing a legacy ABB component with newer Relion hardware, engineers should document the original I/O, communications, protection functions, and wiring architecture rather than selecting a replacement from the article number alone.
Common Error Codes & Diagnostic Symptoms
A specific numeric fault-code list cannot be safely attributed to 1MRK001967 without knowing the host ABB device in which the component is installed.
- Symptom/Code: Hardware/module fault reported by protection device → Diagnosis: Check the host relay’s diagnostic log, module position, power supply, and connector seating → Action: Verify the exact hardware assembly before replacing the module.
- Symptom/Code: Protection relay reports missing I/O or abnormal signal → Diagnosis: Inspect field wiring, terminal connections, module seating, and the relevant I/O configuration → Action: Confirm the affected hardware position and replace only after controlled testing.
- Symptom/Code: Device fails initialization after replacement → Diagnosis: Possible incompatible hardware revision, configuration mismatch, incorrect assembly, or connector problem → Action: Compare the replacement against the original article number, revision, and host-device configuration.
Cross-Reference & Lifecycle Migration
- Exact requested part: ABB 1MRK001967.
- Cross-reference: No direct replacement or equivalent part number should be claimed without confirming the associated ABB equipment model.
- Relion compatibility: The 1MRK numbering system is associated with ABB protection and control equipment, but the article number alone does not establish a specific Relion relay model.
- Firmware: Firmware requirements depend on the host protection device and hardware revision.
- Configuration: If the component is part of a programmable protection device, replacing the hardware may require configuration verification or restoration.
- Hardware revision: Preserve the exact revision whenever possible. A later revision should only be substituted after compatibility is confirmed.
- Lifecycle: Treat this as a legacy/maintenance spare until the complete ABB product identity is confirmed.
- Buffer stock: For critical protection equipment, maintaining a tested exact spare is preferable to relying on an unverified cross-reference.
Field Engineer’s Tech Notes
Warning 1 — Get the complete nameplate. Do not let a supplier quote against 1MRK001967 alone if the application is safety- or protection-critical. Photograph the front label, side label, PCB marking, and the complete relay/device name.
Warning 2 — Record the rack position before removal. Protection hardware is often position-dependent. (A replacement board installed in the wrong slot can produce confusing diagnostic behavior even when the board itself is healthy.)
Strict QA & Testing SOP
- Part identification — Confirm ABB 1MRK001967 against the purchase order.
- Complete device identification — Record the host relay/protection-device model.
- Nameplate inspection — Capture article number, revision, serial number, and product designation.
- PCB inspection — Check internal identification markings where permitted.
- Mechanical inspection — Examine connectors, mounting points, housing, and PCB condition.
- Revision verification — Compare the supplied revision against the installed unit.
- Power inspection — Verify applicable supply requirements using the correct ABB documentation.
- I/O verification — Test the actual I/O function associated with the hardware assembly.
- Communication test — Where applicable, verify the relevant relay communications interface.
- Diagnostic test — Check the host device for hardware and configuration alarms.
- Functional test — Use an approved protection-relay test platform where available.
- Configuration verification — Confirm that the replacement hardware is recognized correctly.
- Final inspection — Document test results, serial number, revision, and physical condition.
- ESD packaging — Package the electronic assembly in anti-static material with impact protection.
- Test evidence — Test videos can be provided when available, particularly for powered functional testing.
Buyer’s FAQ
Q: What is ABB 1MRK001967?
A: It is an ABB protection and control hardware article number. The standalone number does not provide enough verified information to identify its exact electrical function.
Q: Is 1MRK001967 a complete protection relay?
A: It should not be described as a complete relay without confirming the associated ABB product designation. It may represent a hardware assembly or spare component.
Q: Can you provide the exact voltage, channels, or communication protocol?
A: Not reliably from 1MRK001967 alone. Those specifications must be taken from the associated ABB equipment documentation.
Q: Can I replace it with another 1MRK-numbered ABB part?
A: No. Similar article-number formatting does not establish electrical or mechanical interchangeability.
Q: How should I verify a New Original unit?
A: Request clear photographs showing 1MRK001967, the complete ABB product designation, revision, serial number, and PCB markings. For critical protection equipment, request functional-test evidence.
Q: What warranty should I request?
A: Confirm whether the unit is New Original, New Surplus, refurbished, or previously installed, and request a written warranty covering functional performance after installation.
