Product Performance

The module’s logic processing cycle can be configured as 5ms, 20ms or 100ms, supporting access of 8 merging units to meet process layer data acquisition requirements. Voltage measurement accuracy is ≤±0.5% full scale, current measurement accuracy ≤±1.0% full scale, frequency measurement range 45-65Hz with accuracy ±0.01Hz.

It adopts GOOSE communication for inter-bay interlocking, with interlocking response time <1ms. It supports inter-bay interlocking and equipment reservation operation functions to prevent misoperation. Event recording resolution is 1ms, capable of storing 1000 event records and 100 disturbance recording data, with maximum recording duration up to 3.4s.

Built-in intelligent diagnosis module can detect 20 types of faults such as power abnormality, communication interruption, and I/O channel failure, with diagnostic coverage rate ≥99%. Fault information is uploaded to the background system in real time via Ethernet. Mean Time Between Failures (MTBF) is ≥1,000,000 hours (25℃ environment), supporting online configuration download and parameter modification, with configuration update time ≤30 seconds.
