ABB 1MRK000167-GBR00 Retrofit-Ready Signal Conversion for Relion IED Control Systems
The ABB 1MRK000167-GBR00 is a signal conversion module engineered for the ABB Relion IED (Intelligent Electronic Device) protection and control platform. As legacy substation automation systems reach end-of-life and utilities accelerate grid modernization programs, this module serves as a critical retrofit component — enabling engineers to replace discontinued signal interface hardware without redesigning the entire protection scheme or interrupting substation operations.
Whether you are upgrading an aging ABB SPACOM or PYRAMID relay panel to the Relion 615, 620, or 650 series, or restoring a failed signal conversion path in an existing Relion bay controller installation, the 1MRK000167-GBR00 provides a verified, factory-tested replacement that preserves your existing wiring topology and IEC 61850 communication architecture.

Retrofit Planning for Existing Automation Systems
Successful integration of the 1MRK000167-GBR00 into an existing substation or industrial control cabinet requires a structured retrofit plan. Engineers should begin by auditing the existing ABB REF615 or RET620 bay unit to confirm the current signal conversion module’s terminal assignments and verify that the replacement module’s I/O channel count matches the legacy wiring harness.
Power supply capacity is the first checkpoint: confirm that the station battery or ABB PSM600 power supply module can sustain the additional load introduced by the new signal conversion path. Most Relion bay units operate on 24–250 V DC auxiliary supply, and the 1MRK000167-GBR00 must be energized within this range before any terminal connections are made.
Terminal block wiring should be mapped against the original ABB TDB (Terminal Diagram Block) drawings. Where the legacy system used screw-type terminals, confirm compatibility with the Relion’s push-in terminal standard or use appropriate ferrule adapters. The ABB COMBIFLEX relay output module or any intermediate marshalling cubicle wiring must be re-verified after module swap.
Backplane and rack interface checks are equally important. If the 1MRK000167-GBR00 is installed within a Relion 650 series multi-function protection IED, confirm that the module address is correctly assigned in the PCM600 project configuration tool. Incorrect module addressing will prevent the IED from recognizing the new hardware and may trigger a configuration mismatch alarm on the ABB MicroSCADA Pro or Ellipse EAM asset management system.
For sites migrating from legacy MODBUS RTU to IEC 61850 GOOSE communication, the signal conversion module plays a pivotal role in bridging the old hardwired intertripping scheme to the new logical node architecture. Coordinate with the protection engineer to update the IEC 61850 SCL/SCD configuration file before energizing the new module. The ABB COM600 station gateway or RTU560 remote terminal unit may also require dataset and report control block updates to reflect the new signal path.
HMI screen updates on the ABB Operator Panel OP3 or third-party SCADA displays should be completed in parallel with the hardware swap to ensure that alarm annunciation and status indications remain accurate after commissioning. Confirm that all analog input scaling factors and binary output assignments are re-entered in the IED parameter set before returning the bay to service.
Downtime Control During System Migration
Minimizing outage duration is the primary operational constraint in any live substation or continuous-process plant retrofit. For the 1MRK000167-GBR00 replacement, a structured hot-standby approach is recommended: pre-configure the replacement module offline using PCM600, load the parameter set from the existing IED backup, and validate all I/O assignments in a bench-test environment before the scheduled maintenance window.
During the physical swap, isolate only the affected bay unit — not the entire protection panel. Use the Relion IED’s built-in test mode to inhibit trip outputs while the module is replaced, preserving the protection scheme’s logical continuity. The ABB REX640 or adjacent bay IEDs can maintain busbar protection coverage during the single-bay outage, provided GOOSE subscriptions are correctly maintained.
After module installation, perform a staged energization sequence: apply auxiliary power first, confirm module self-test LED status, then re-enable communication links and verify GOOSE message reception at the subscribing IEDs. Complete a full functional test of all binary inputs and outputs before releasing the bay to normal service. Total planned outage for a single-module swap typically ranges from 2 to 4 hours when pre-commissioning steps are completed in advance.
All replacement modules supplied by SMARTNEXMSK are pre-tested under factory conditions and shipped with a test report. The 12-month warranty covers manufacturing defects and functional failure under normal operating conditions, providing assurance for both planned retrofits and emergency spare replacements.
Retrofit Support FAQ
Q1: Is the 1MRK000167-GBR00 a direct drop-in replacement for the original ABB Relion signal conversion module?
A: Yes, for the compatible Relion IED series (615, 620, 630, 650). Terminal pinout and mechanical dimensions are consistent with the original factory specification. Re-parameterization via PCM600 is required after installation to confirm module address and I/O channel assignments.
Q2: What wiring checks are mandatory before powering up the replacement module?
A: Verify auxiliary supply voltage range (24–250 V DC), confirm terminal block ferrule compatibility, check that all binary input and output wiring matches the original TDB drawings, and ensure the module address DIP switch or software setting matches the PCM600 project configuration.
Q3: Can this module be used in a system that has already migrated to IEC 61850?
A: Yes. The 1MRK000167-GBR00 is compatible with IEC 61850-based Relion IED installations. After replacement, update the SCD file in PCM600 and re-publish the dataset configuration to the COM600 gateway or RTU560 to restore full GOOSE and MMS communication.
Q4: What does the 12-month warranty cover, and how is it claimed?
A: The warranty covers manufacturing defects and functional failure under normal operating conditions for 12 months from the date of shipment. To initiate a warranty claim, contact SMARTNEXMSK with the original invoice, a description of the failure, and the module serial number. Replacement or repair will be arranged within the warranty period at no additional cost.
