Product Performance

The module’s analog signal conversion accuracy is ≤±0.05% full scale. Combined with a built-in temperature sensor for error compensation, the temperature drift is controlled within ≤0.001% full scale/℃. The time synchronization accuracy reaches ±100ns, enabling precise timing alignment of data acquisition between multiple modules.

The digital signal response time is ≤1ms, and the output circuit supports short-circuit protection, automatically limiting current to 2.5A during overload. The communication link data transmission delay is ≤5ms, supporting Modbus RTU/TCP protocol for real-time upload of conversion data and equipment status information.

It has a built-in fault diagnosis module that can detect fault types such as ADC abnormalities, power fluctuations, and communication interruptions, with a diagnostic coverage rate ≥99%. Fault information is fed back through both indicator lights and communication bus. The module’s Mean Time Between Failures (MTBF) is ≥1,000,000 hours (25℃ environment), supporting online parameter configuration, enabling range and gain adjustment without power-off.
