4. Low power consumption and high reliability, maintenance-free long-term operation

Using low-power CMOS circuit, powered by the workstation's internal + 5V, typical power consumption **≤2W**, minimal heat generation, no need for additional cooling, reducing energy consumption and failure risks. Power input integrates overcurrent, overvoltage, reverse connection protection, resisting voltage fluctuations, surges, wiring errors, protecting the board card safety. Average failure-free time (MTBF) exceeds 100,000 hours, no moving parts, long-term operation requires no frequent maintenance, suitable for continuous operation in industrial sites.

5. Status monitoring and self-diagnosis, simplifying operation and maintenance

The board integrates power and operation status monitoring circuits, combined with the workstation panel indicator lights (PWR/RUN/FAULT) to provide real-time feedback on status: PWR constantly on = normal power supply; RUN flashing = memory is working normally; FAULT constantly on = read/write errors, chip damage or bus conflict. No need for professional tools, through the indicator lights, you can quickly determine the status and locate the fault, simplifying the operation and maintenance process, reducing troubleshooting time.
