1MRS050644 ABB high-performance acquisition card

Technical Parameters:

Sampling Rate: High-speed analog-to-digital (A/D) conversion capable of processing multi-channel current and voltage wave signals at up to 80 samples per cycle.

Processing Core: Embedded real-time microprocessor optimized for instantaneous calculation of protective relaying algorithms and high-speed fault detection.

Input Channels: Integrates high-accuracy instrumentation inputs for Current Transformers (CT) and Voltage Transformers (VT), featuring low thermal drift and minimal phase error.

Data Interface: High-bandwidth internal bus connector designed for seamless, real-time communication across the IED backplane assembly.

Network Protocols: Natively supports digital communication protocols including IEC 61850 (GOOSE and Sampled Values), Modbus, and DNP3 via the main chassis network link.

Electromagnetic Compatibility: Fully compliant with IEC 60255 series standards, providing superior isolation against high-voltage surges, transient disturbances, and intense electromagnetic interference (EMI).

Industrial Sectors:

Electrical Power Transmission and Distribution, Substation Automation Utilities, Renewable Energy Generation (Wind and Solar Grid Integration), Petrochemical and Heavy Industrial Power Plants, and Rail Transportation Infrastructure.

Application Scenarios:

1. High-Speed Substation Protection: Installed inside ABB Relion 615 series protective relays to handle continuous, real-time data acquisition of feeder or motor line currents, enabling immediate trip execution during overcurrent or short-circuit faults.

2. Waveform Disturbance Recording: Deployed in utility substations to capture and log transient power grid anomalies, high-frequency harmonics, and voltage sags, preserving accurate pre-fault and post-fault data for analytical review.

3. Power Quality Monitoring: Functions as the precise measurement engine within intelligent grid nodes to evaluate total harmonic distortion (THD), phase frequency drift, and unbalance conditions in harsh industrial microgrids.

4. Smart Switchgear Interfacing: Serves as the primary data acquisition bridge between primary physical switchyard equipment (switches, breakers, transformers) and secondary digital automation networks operating under IEC 61850 standards.
