Product Performance

Signal acquisition response is fast, with input response time ≤1ms per channel, enabling real-time capture of on-site equipment status changes to meet the real-time requirements of high-speed control loops such as gas turbine start-stop control and valve switching. Channel-level diagnostic functions cover full-scenario abnormalities such as short circuits, open circuits, and overvoltages; diagnostic coverage rate ≥99%. In case of faults, local LEDs and bus signals synchronize alarms, allowing maintenance personnel to quickly locate problems and reduce troubleshooting time.

Hardware stability is excellent, adopting industrial-grade components and wide-temperature design. Mean Time Between Failures (MTBF) ≥1.2×10⁶ hours (MIL-HDBK-217F standard, 25℃ environment), enabling continuous and stable operation in industrial scenarios with high temperature, high dust, and strong electromagnetic interference. It supports hot-swapping, with module live replacement time ≤10 seconds; the replacement process does not affect signal acquisition of other channels or system operation, improving maintenance efficiency.

System compatibility is strong, fully adapting to the programming software of GE Mark VI control system (e.g., ToolboxST), supporting online channel configuration, diagnostic parameter adjustment, and firmware upgrade. Parameter updates can be completed without interrupting the system, adapting to the expansion and upgrade needs of existing automation architectures.
