Description
ABB 1MRK000614-ABR01 Binary Output Module
Product Introduction
When an ABB protection IED has to issue multiple hardwired commands to breakers, alarms, interlocks, or auxiliary circuits, the binary output hardware becomes a critical interface between relay logic and the plant wiring. ABB 1MRK000614-ABR01 is identified as a Binary Output Module (BOM) with 24 binary outputs, corresponding to ABB’s 1MRK000614-AB product family. ABB catalog data describes the base article as a 24-output-relay module.
The ABR01 suffix should be treated as a complete procurement identifier, not simply ignored in favor of the base article. A procurement specification for the exact 1MRK000614-ABR01 lists 24 BOs and a maximum output voltage of 250 VAC/DC. For replacement work, confirm the host IED, hardware revision, terminal arrangement, and application wiring before assuming that another 1MRK000614 variant is a direct replacement.

*The 250 VAC/DC figure is documented in a procurement specification for the exact ABR01 article. It should be treated as a maximum voltage rating, not as a statement that every output configuration can switch any 250 VAC/DC load at any current.
Application Scenarios & Pain Points
Protection Relay Output Control
The BOM provides the physical output interface required when protection logic must operate external devices. In a substation, this can include breaker-control circuits, annunciation, interlocking, and other discrete signaling functions.
1MRK000614-ABr01
Multi-Point Hardwired Signaling
With 24 binary outputs, the module is suited to protection schemes where a single IED has to distribute multiple discrete status or command signals. ABB documentation and utility procurement records identify the base 1MRK000614-AB product specifically as a 24-output-relay BOM.
Legacy ABB Protection-System Maintenance
This part number is particularly relevant when maintaining an installed ABB protection system where the original hardware configuration must be preserved. Do not replace it based only on the description “24-channel relay output.” The exact suffix and host IED configuration still matter.
Procurement and Spare Replacement
For a spare BOM, photograph the existing board label before removal. Record 1MRK000614-, the host IED type, hardware revision, terminal arrangement, and any associated BOM documentation. This takes minutes and can prevent a costly mismatch later.

Engineer’s Guide — Field Pitfalls to Avoid
1. Do not confuse with the generic AB article.
The base product 1MRK000614-AB establishes the 24-relay BOM family, but the installed hardware should still be matched by its complete ordering number.
2. Do not interpret 250 VAC/DC as a universal load-current rating.
The exact procurement record specifies Umax: 250 VAC/DC, but it does not establish a permissible current for every load type. Breaker trip coils, contactors, solenoids, and annunciator circuits can have very different electrical characteristics.
3. Check the external circuit before energizing a replacement.
A relay output that is electrically suitable at the voltage level can still be inappropriate for an inductive load if suppression, contact arrangement, or switching duty differs from the original design.
4. Verify the host IED configuration.
This is a protection-system component rather than a generic PLC output card. The physical mounting position, terminal connections, and system configuration must match the original installation.
5. Do not assume , ABR02, and ABR04 are interchangeable.
Public procurement and catalog records show several revisions of the 1MRK000614 family. A different suffix is a reason to perform a compatibility check—not a reason to assume a drop-in replacement.
6. Inspect the actual board revision.
For used or surplus inventory, request photographs of the ABB nameplate and PCB markings. A seller’s generic description may identify the family correctly while omitting the revision that matters to the protection-system engineer.
FAQ
What is ABB 1MRK000614-?
1MRK000614- is an ABB Binary Output Module (BOM) with 24 binary/relay outputs. The exact article is documented in procurement records with 24 BOs.
How many outputs does 1MRK000614- have?
It has 24 binary outputs. ABB’s base product record for 1MRK000614-AB also describes the module as having 24 output relays.
Is 1MRK000614- a power supply module?
No. The more reliable identification is Binary Output Module (BOM). Some third-party listings incorrectly describe the article as a power-control or power module, but ABB catalog information and utility procurement records identify the 1MRK000614 family as a binary output module.
What is the maximum output voltage?
A procurement specification for 1MRK000614- states Umax = 250 VAC/DC. This should not be interpreted as a complete load-rating specification; the permissible current and load type still need to be checked against the applicable ABB documentation.
Can 1MRK000614- replace 1MRK000614-ABR02?
They belong to the same BOM family, but a different suffix should not automatically be treated as a drop-in replacement. Confirm the host IED, hardware revision, wiring, and ABB compatibility documentation first.
Is 1MRK000614- suitable for PLC applications?
It is better classified as ABB protection and control IED hardware, not as a general-purpose PLC output module. Using it outside its documented ABB system architecture would require separate engineering verification.
What should be checked before purchasing a replacement?
Provide the supplier with the complete 1MRK000614- number, host protection relay model, hardware revision, photographs of the existing board label, and terminal/wiring information. For a protection-system spare, matching the exact hardware article is more important than matching only the phrase “24-relay output module.”
