ABB 1MRK002133-ABr02 | Replacement Binary Output Module for ABB Relion IEDs

Description

• Model: 1MRK002133-ABr02
• Brand: ABB
• Series: Relion 670 Series
• Part Type: Binary Output Module / I/O Hardware
• Core Function: Provides binary output functionality within ABB Relion protection and control IED hardware.
• Key Specs: ABB 1MRK002133-ABr02; Relion 670 family; binary-output hardware; revision r02; used in protection and substation automation applications.
• System Role: Interfaces protection logic with external control circuits such as breaker, alarm, interlocking, or signaling functions.

Current supplier references consistently associate 1MRK002133-ABr02 with ABB Relion 670-series hardware, although some secondary listings incorrectly describe it as an analog/digital converter or unrelated control board. The binary-output classification is therefore the more relevant identification for this part number.

Product Introduction

A protection IED can detect a fault correctly and still fail to complete the protection sequence if its output hardware cannot issue the required trip, alarm, or control signal. That is why output-module condition matters just as much as the protection algorithms running inside the relay.

ABB 1MRK002133-ABr02 is identified in current ABB-related spare-part references as a Binary Output Module for the Relion 670 Series. The part belongs to ABB’s Relion protection and control ecosystem used in substations and industrial power systems.

The r02 suffix should be retained when sourcing a replacement. For installed protection equipment, hardware revision, IED type code, firmware compatibility, and the configured binary-output assignments should all be checked before commissioning. (Do not substitute a visually similar Relion I/O board simply because the connector arrangement appears comparable.)

Core Technical Specifications

ABB 1MRK002133-ABr02

ABB-related product references identify 1MRK002133-ABr02 specifically as a binary-output module associated with the Relion 670 series.

Specification caution: Public aftermarket sources give conflicting channel counts, output ratings, dimensions, and supply information for this part. Those figures should not be treated as confirmed ABB specifications without the applicable ABB hardware manual or the exact IED configuration. For procurement, the complete order code and installed IED type code are more reliable than generic catalog specifications.

Application Scenarios & Pain Points

In a protection system, the binary-output path is where a digital protection decision becomes a physical control action.

1. Feeder Protection

For a feeder protection IED, binary outputs may be assigned to trip commands, breaker status logic, alarms, and interlocking functions. A defective output circuit can prevent an otherwise correctly detected fault from reaching the associated control circuit.

2. Substation Switchgear

Within medium- and high-voltage switchgear, protection IEDs exchange control signals with circuit breakers and auxiliary equipment. An output-module problem can therefore affect breaker control or annunciation.

3. Transformer Protection

Transformer protection schemes often require multiple discrete signals for trip, alarm, blocking, and interlocking. When an output remains inactive despite the protection logic operating correctly, the output hardware and wiring should be investigated.

4. Industrial Power Distribution

Manufacturing facilities with dedicated substations may use Relion protection IEDs for critical feeders and motors. A verified spare 1MRK002133-ABr02 can help reduce restoration time during an unexpected protection-system failure.

5. High-Temperature Switchgear Panels

At 50°C+ internal panel temperatures, inspect ventilation and terminal conditions carefully. Thermal stress can accelerate degradation of electronic output circuitry and create intermittent behavior.

Common Error Codes & Diagnostic Symptoms

No reliable ABB source establishes a dedicated numerical fault code specifically for 1MRK002133-ABr02. Diagnosis should therefore combine IED event records, binary-output status, wiring checks, and hardware substitution.

• Symptom/Code: Protection operates but external trip output remains inactive → Diagnosis: Possible binary-output channel failure, configuration mismatch, wiring fault, or output supervision issue → Action: Verify the configured output matrix and terminal circuit; substitute the module if the hardware fault is isolated.
• Symptom/Code: Binary output remains permanently asserted or deasserted → Diagnosis: Possible output-channel hardware failure or external circuit problem → Action: Compare the IED logic status with the physical output state and test the associated circuit before replacing the module.
• Symptom/Code: Output-module hardware diagnostic alarm → Diagnosis: Internal module, communication/backplane, or hardware-revision problem may be preventing normal operation → Action: Review the IED diagnostic/event log, verify module identification, and replace with a confirmed compatible unit if required.

Cross-Reference & Lifecycle Migration

Exact Identification

Compatibility

The critical compatibility check is not simply “Relion 670.” Verify the complete:

• IED type designation
• Order code
• Hardware revision
• Firmware version
• Binary-output assignment
• Terminal configuration
• Existing configuration file
• Protection/control application

ABB’s Relion platform uses configurable IED hardware and application functions, so the same physical family does not automatically establish interchangeability.

Previous Revision / Replacement

Public references do not establish a universal predecessor or direct successor for 1MRK002133-ABr02. The r02 suffix should therefore be preserved during sourcing.

A later hardware revision should only be substituted after checking ABB compatibility documentation and the installed IED’s firmware/configuration requirements.

Firmware / Configuration

Firmware compatibility should be verified before commissioning. If the replacement hardware revision differs from the original, check the supported IED firmware and configuration in PCM600 before returning the protection system to service.

Lifecycle Status

Lifecycle: Legacy / Mature

The Relion 670 family is an established protection platform. For an installed substation system, maintaining a tested spare of the exact hardware revision is prudent, particularly where a failed binary-output module could affect breaker control or protection signaling.

Field Engineer’s Tech Notes

Tech Note 1 — Separate “logic operated” from “output operated.”
When troubleshooting a failed trip signal, first check whether the protection function actually issued the binary command. If the IED logic indicates operation but the physical output does not change state, focus on the output channel, terminal circuit, and configuration rather than immediately changing protection settings.

Tech Note 2 — Do not change the output mapping during a fault investigation.
Record the existing binary-output assignment before replacing or reconfiguring the hardware. (Changing the mapping can introduce a second problem and make the original failure much harder to isolate.)

Strict QA & Testing SOP

Buyer’s FAQ

Q: Is 1MRK002133-ABr02 a binary output module?
A: Current ABB-related spare-part references identify it as a Binary Output Module for the Relion 670 Series. Several aftermarket pages give contradictory descriptions, so the physical label and installed IED type code should be checked before purchase.

Q: Can I install this module while the protection relay is energized?
A: Do not assume it is hot-swappable. Protection IED hardware should be replaced according to the applicable ABB maintenance procedure, with the relevant protection and control circuits placed in the required safe state.

Q: Does a replacement require firmware or configuration work?
A: It may, depending on the IED model, hardware revision, and existing configuration. Verify firmware compatibility and the binary-output mapping in the installed system before commissioning.

Q: How do I verify an authentic replacement?
A: Request photographs of the actual unit showing the 1MRK002133-ABr02 label and revision, plus a functional test report. For a protection-system spare, also request confirmation of compatibility with the specific Relion IED type code and written warranty terms.
