ABB 1MRK000167-GBR00 Replacement for Relion IED Series

Product Overview

ABB 1MRK000167-GBR00 Replacement for Relion IED Series: Seamless Migration & Upgrade

The ABB 1MRK000167-GBR00 is a signal conversion module designed for use within ABB’s Relion protection and control IED (Intelligent Electronic Device) platform. As legacy protection relay systems age and original ABB modules approach end-of-life or become increasingly difficult to source, plant engineers and substation maintenance teams face mounting pressure to maintain system integrity without triggering a full panel replacement. This listing provides a verified replacement and upgrade solution for the 1MRK000167-GBR00, sourced from authorized supply channels and tested prior to dispatch.

Whether you are maintaining an existing Relion 611 series, Relion 615 series, or Relion 620 series protection relay installation, or migrating from an older ABB SPACOM or PYRAMID protection system, the 1MRK000167-GBR00 signal conversion module plays a critical role in bridging analog signal inputs to the IED’s internal processing architecture. Its replacement must be handled with precision to avoid misconfiguration of protection thresholds, communication loss, or relay misoperation.

Seamless Upgrade Solutions

A successful migration involving the 1MRK000167-GBR00 rarely occurs in isolation. In most substation and industrial protection panel retrofits, this signal conversion module is replaced as part of a broader IED maintenance or upgrade campaign. During such projects, engineers commonly address adjacent components to minimize future downtime and ensure system-wide compatibility.

When replacing the 1MRK000167-GBR00, teams frequently audit the IED’s binary input/output modules — such as the ABB RBIO or RDIF I/O cards — to confirm that signal routing from field devices like current transformers, voltage transformers, and protection relays remains intact. In installations where the Relion IED communicates over IEC 61850, the station bus interface module (often an RJ45 or fiber-optic communication card within the same IED chassis) should be verified for firmware compatibility with the updated signal conversion module.

For sites migrating from older ABB SPACOM protection relays or first-generation Relion 611 units, the upgrade path often includes replacing the entire IED front-end assembly, which may involve the ABB Relion 615 or 620 series main processing unit alongside the 1MRK000167-GBR00. In these cases, the PCM600 engineering tool is used to export existing protection parameter sets, which can then be imported into the replacement IED with minimal reconfiguration — significantly reducing commissioning time on site.

Power supply integrity is another key consideration. The Relion IED platform operates from a station DC bus, typically 110 V DC or 220 V DC. If the existing ABB PISA or PSMV auxiliary power supply module shows signs of aging, it is advisable to replace it concurrently with the signal conversion module to avoid a secondary outage. Similarly, the IED’s human-machine interface panel — whether a local LCD display module or a remote HMI connected via the SPA bus — should be tested post-replacement to confirm alarm and event display continuity.

In control cabinet installations where multiple Relion IEDs share a common communication gateway, such as the ABB COM600 or COM610 substation gateway, the gateway’s IEC 61850 dataset configuration should be reviewed after any module swap to ensure that GOOSE message subscriptions and report control blocks remain correctly mapped. Failure to do so can result in silent protection gaps that are difficult to detect without a full secondary injection test.

For sites using PROFIBUS DP or MODBUS RTU as a legacy communication backbone alongside IEC 61850, the signal conversion module replacement may also require updating the protocol conversion settings within the IED’s communication configuration file. Our technical team can provide pre-sales guidance on PCM600 parameter compatibility upon request.

Retrofit Guidance FAQ

Q: Can I replace the 1MRK000167-GBR00 without rewiring the terminal block?
A: Yes. The replacement module uses the same physical slot and terminal assignment as the original. Existing field wiring connected to the IED’s terminal block does not need to be modified, provided the IED chassis and terminal block assembly are undamaged.

Q: Do I need to reconfigure the IED in PCM600 after replacing this module?
A: In most cases, the existing PCM600 application configuration file (ACT) can be reloaded without modification. However, it is recommended to perform a full parameter verification and secondary injection test after any module replacement to confirm protection function integrity.

Q: Is this module compatible with IEC 61850 GOOSE messaging?
A: Compatibility with IEC 61850 GOOSE depends on the IED platform version and firmware. The 1MRK000167-GBR00 operates within the Relion IED’s internal architecture and does not independently handle GOOSE — the IED’s communication module manages protocol-level messaging. Confirm your IED firmware version with our team before ordering if IEC 61850 interoperability is a critical requirement.

Q: What if my control cabinet has limited space for a replacement module?
A: The 1MRK000167-GBR00 is a slot-in module for the Relion IED chassis. It does not require additional panel space beyond the existing IED footprint. No additional DIN rail mounting or external enclosure is needed.

Q: How do I verify the module is functioning correctly after installation?
A: After installation, use PCM600 to perform a live parameter read-back and check the IED’s self-supervision (SELFSUPERVISION) function block for any hardware fault indications. A secondary injection test using a relay test set is recommended to confirm analog signal conversion accuracy.
