ABB 1MRK002246-BD Main Processing Board for Relion IED

Description

Hardware and Performance Specifications Auxiliary supply: Powered by IED internal back‑plane bus Processor: High‑reliability industrial processor for real‑time protection calculation Communication interfaces: Internal back‑plane high‑speed bus; interfaces for front‑panel HMI, Ethernet and optical communication modules Mounting mode: Plug‑in subrack board for Relion 670‑series IED chassis Protection class: IP20 Operating temperature: ‑25 ℃ ~ +70 ℃ Storage temperature: ‑40 ℃ ~ +85 ℃ Humidity: 5‑95 %RH non‑condensing EMC compliance: Comply with IEC 61000‑4 series industrial EMC standards, comply with IEC 60255 protection relay standards Dimension & weight: 165 × 115 × 30 mm, weight approx. 0.42 kg Certifications: CE, UL

Main Functions Execute real‑time power‑system protection and control algorithm calculations. Process logic interlock, breaker control, auto‑reclosing and synchrocheck functions. Manage time‑stamped event logging and disturbance fault‑waveform recording. Handle data communication with bay control unit, SCADA and DCS system. Realize local HMI display, parameter setting and man‑machine interaction. Hardware self‑diagnosis for internal circuit, memory and bus channel monitoring; generate fault alarm codes when abnormality occurs. IED configuration, parameter setting and firmware upgrade are completed by ABB PCM600 engineering tool.

Installation Requirement Plug‑in installation inside Relion 670‑series IED chassis. Ensure reliable cabinet protective grounding. After board replacement, confirm hardware revision 1MRK002246‑BD strictly matches original project configuration, download complete IED configuration file. Perform self‑diagnosis check, I/O loop test and communication verification. Different hardware revisions (‑BD /‑BE /‑BF) are not directly interchangeable without firmware adaptation and configuration download. Do not put into service until no hardware self‑diagnosis fault alarm exists.

Typical Application Scenarios Main processing board for Relion 670‑series protection and control IEDs, widely used in power‑grid substations, thermal‑power plants and hydropower plants, applied for substation‑automation‑system maintenance and spare‑part replacement.

Key Features

1. Core main‑processing unit for Relion 670‑series IEDs, undertakes all real‑time protection‑calculation and logic‑processing tasks.
2. High‑reliability hardware design for long‑term stable operation in harsh substation environment.
3. Rich self‑diagnosis functions, convenient for on‑site fault locating.
4. Plug‑in card structure, convenient for on‑site replacement and maintenance.
5. Critical spare‑part for ABB Relion protection‑relay system; full part‑number and hardware‑revision matching must be strictly observed during replacement.
