Product Performance

The module adopts a dedicated 32-bit processing chip with an operation speed ≥100MIPS, enabling parallel processing of multi-channel signals. The analog sampling rate reaches 10kHz, which can accurately capture subtle changes in equipment operating parameters. Integrated with an adaptive filtering algorithm, it effectively suppresses electromagnetic interference in industrial sites and maintains signal stability even in 690V high-voltage inverter environments.

The fault diagnosis function can real-time monitor fault status such as power abnormality, communication interruption and signal over-limit, with fault response time ≤10ms. Fault information is actively reported through the communication interface, and at the same time triggers local indicator alarm. The module supports online parameter configuration and program upgrade, which can be maintained without disassembly, adapting to the non-stop maintenance needs of industrial equipment.

It is fully compatible with Toshiba MegaVert series inverters and third-party PLC systems, with data interaction delay ≤5ms, meeting the real-time control requirements of high-voltage frequency conversion systems. The mean time between failures (MTBF) is ≥500,000 hours, complying with industrial-grade long-life operation standards.
