Description

500MTM02 1HDF930512X010 is a multifunctional measurement module (analog input unit) launched by ABB. It is a core component of the Relion® series protective relays, specifically designed for precise measurement and protection in high-voltage power systems. The following is detailed product information compiled from publicly available technical data:

Core Functions and Advantages

1. High-Density and High-Precision Measurement: Supports 6-channel voltage (VT) + 6-channel current (CT) inputs, with high channel density capable of covering three-phase voltage/current, zero-sequence voltage/current, bus voltage, and other key electrical measurements; sampling accuracy reaches ±0.2%, and the sampling rate supports 16/24/48 points per cycle (configurable), allowing for capturing subtle signal changes during faults.

2. Strong Anti-Interference and Safety Design: Input channels are isolated from each other and from ground with 4kV AC withstand voltage (for 1 minute continuously), effectively preventing high-voltage surges from damaging the equipment; multiple anti-interference technologies such as shielding, filtering, and differential input are employed, suitable for substations with strong electromagnetic interference.

3. Intelligent Expansion Functions: With X010 firmware, supports advanced functions such as power quality monitoring, fault recording, and harmonic analysis; compatible with IEC 61850 standard, enabling digital substation network data transmission and sharing through SV (Sample Value) and GOOSE (Generic Object-Oriented Substation Event) protocols.

4. High Compatibility and Integrability: Maintains stable communication with the main CPU via the backplane, allowing seamless integration into the ABB Relion® protection device system; modular plug-in design facilitates installation, replacement, and system expansion.
