ABB 1MRK001370-AA 1MRK000005-189 Relay Module Product Description

Overview

ABB 1MRK001370-AA is the hardware module identifier, 1MRK000005-189 is the configuration/software variant code, belonging to ABB RELION 670 series protection and control IED family. This ABB module is a plug-in signal interface or main CPU/communication board for line protection, bay control, transformer protection IEDs in substation automation systems. It is widely used for power substation bay control cabinet maintenance, protection IED overhaul and spare‑part replacement of RELION 670 series equipment.

Features

ABB 1MRK001370-AA 1MRK000005-189 follows IEC 61850 substation communication standard, supporting GOOSE, MMS and SV process bus communication. This board provides galvanic isolation for analog CT/VT sampling signals and binary input/output interlock signals. 1MRK001370-AA 1MRK000005-189 carries built-in self-supervision, memory checksum and watchdog diagnosis; it will report internal hardware faults to the station HMI. It supports configurable binary interlocking, trip logic and disturbance recording function. The firmware license and function set are locked under suffix 1MRK000005-189, and it can work with PCM600 engineering tool for parameter setting and disturbance file analysis. It complies with IEC 60255 relay standard and substation EMC requirements.

Principle

ABB 1MRK001370-AA 1MRK000005-189 receives CT/VT analog sampling signals and binary status signals from the bay primary equipment. The onboard processor executes protection algorithms, interlock logic and measurement calculation. It exchanges interlock and trip signals with other IEDs via GOOSE, uploads measurement and alarm data to the station control system. When protection conditions are satisfied, it outputs trip command to the circuit breaker control circuit and records fault event and oscillography data.

Applications

ABB 1MRK001370-AA 1MRK000005-189 is deployed in high-voltage and medium-voltage power substations, industrial plant power distribution substations. This RELION module is used for feeder protection, bay control, transformer protection and switchgear interlock control. 1MRK001370-AA 1MRK000005-189 fits protection IED maintenance and spare replacement of ABB RELION 670 series plug-in boards.

Installation & Maintenance Notes

Follow official ABB RELION 670 hardware manual and substation safety rules during replacement of 1MRK001370-AA 1MRK000005-189. Isolate CT secondary circuit to prevent open circuit hazard. Use ESD protection before touching the board. Back up IED parameter setting, disturbance record and GOOSE configuration before swap. After replacement, download parameter set, verify IEC 61850 communication and interlock logic. Confirm the full part code 1MRK001370-AA and configuration code 1MRK000005-189 match; different software variants have different function licenses and cannot interchange directly.
