Description

1MRK001967-AA is an industrial-grade core module launched by ABB, corresponding to the functional model 500MTM02. It combines input/output (I/O) processing with multifunctional measurement capabilities and is a key component in power system protection and industrial automation. Below is a detailed compilation of the product information:

Product Core Positioning and Affiliation

1. Product Identity: ABB official material number 1MRK001967-AA, functional model 500MTM02, hardware version identifier 1HDF 930512, typical firmware version X010.

2. Series Affiliation: Dual adaptation scenarios — firstly, the core processor module of ABB MUM8000 (Multi-Utility Manager 8000) protection and control system; secondly, the multifunction measurement module of ABB Relion® series (such as REL670, REL650, REL630) protection relays.

3. Core Mission: To undertake critical tasks in the power system such as accurate electrical measurement, protection logic execution, data transmission, and fault response, serving as a key component to ensure device safety and system stability.

Core Functions

1. Measurement and Signal Processing: Supports 6 voltage (VT) + 6 current (CT) inputs, capable of acquiring three-phase voltage/current, zero-sequence voltage/current, and other key electrical quantities. It converts analog signals to digital signals with high precision, providing data support for protection algorithms.

2. Protection Logic Execution: As the main processor of the MUM8000 system, it can run various protection algorithms such as overcurrent, differential, distance, and directional protection. In case of faults (e.g., short circuits, ground faults), it issues trip commands within milliseconds to isolate the fault point.

3. Data Communication and Interaction: Communicates with the main CPU via the backplane, supporting protocols like IEC 61850-9-2 LE (SV) and GOOSE. It can interact with substation automation systems (SCADA), HMI, or third-party devices, uploading events, alarms, and measurement data, and receiving configuration commands.

4. Self-Diagnosis and Maintenance: Equipped with hardware/software self-check functions, it displays power, operation, fault, and communication status via LED indicators for quick on-site diagnosis. It supports fault recording and event logging to assist in accident analysis.

Product Features and Advantages

1. High Reliability: Adopts a redundant design and rigorous EMC testing, with a metal casing for protection. Can withstand strong electromagnetic interference, surges, and other harsh conditions on power sites, ensuring long-term stable operation.

2. Modular and Flexible: Supports flexible configuration and can be combined with other functional modules according to different needs such as line protection and transformer protection, adapting to diverse application scenarios.

3. Precision and Efficiency: High-precision sampling and fast signal processing capabilities capture minute changes during faults, and, together with mature firmware, enable expanded functions like power quality monitoring and harmonic analysis.

4. Easy Integration and Maintenance: Standardized interface design allows seamless integration with ABB series PLCs, protection relays, and third-party control systems; modular structure facilitates installation, replacement, and subsequent maintenance.
