Employs a 4U standard chassis with a modular front plug-and-play structure, versatile and interchangeable circuit design, ease of maintenance, and convenient technology upgrades. A single main control board handles both algorithm processing and communication functions, ensuring a simple and reliable system architecture.

Features multi-level isolation and effective shielding measures from the chassis to the PCB design and component selection. Adherence to ISO9000:2000 standards during manufacturing using surface mount technology ensures excellent electromagnetic compatibility and high operational reliability without requiring external anti-interference measures for panel assembly, simplifying design and maintenance.

Within a compact 4U, 19-inch core unit, it supports up to 16 circuits, with each circuit providing 3 remote measurements, 7 remote signals, and 2 remote controls.

The device maintenance tool software offers comprehensive configuration options for device channels, fixed value parameters, and forwarding point tables. This allows for easy adaptation to various engineering applications through configuration rather than program modification, significantly enhancing device reliability.

The device maintenance tool software is organized into common, engineering, production, and development sections, providing comprehensive maintenance functions for personnel with different roles.

Supports cyclic storage of over 64 waveform recording sets, capturing 4 cycles before and 8 cycles after a fault with a sampling rate of 128 points/cycle. Simultaneous recording of 2 circuits is possible. Fault recording triggers include overcurrent faults, line voltage loss, zero-sequence voltage, and sudden changes in zero-sequence current, with remote and local setting of trigger parameters.
