Product Performance
The module is certified to IEC 61508 SIL 3, with a safety integrity level meeting the requirements of safety-critical scenarios such as Emergency Shutdown (ESD) and fire alarm; the 32-channel independent isolation design ensures that a single channel fault (e.g., short circuit, open circuit) does not affect other channels, with a fault isolation rate of 100%.
The digital signal response time is ≤1ms (when filter time is 0.1ms), which can quickly capture changes in on-site equipment status and avoid safety risks caused by signal delay; the built-in digital filter function can effectively suppress electromagnetic interference in industrial environments, with signal jitter filtering accuracy ≤0.1ms, ensuring the accuracy of signal acquisition.
The fault diagnosis coverage is ≥99.5%, which can real-time detect faults such as channel open circuit, short circuit, power undervoltage, and communication interruption. Fault information is uploaded to the HIMax controller in real time via the safety bus, and the local fault indicator is triggered simultaneously; the module’s Mean Time Between Failures (MTBF) is ≥1,200,000 hours (MIL-HDBK-217F, 25℃ environment), adapting to 24/7 continuous production scenarios.
It supports hot-swapping operation, with a module replacement time of ≤15 seconds. During replacement, the controller automatically maintains the channel history status without restarting the system; it is compatible with all series of HIMA safety controllers, and signal types, filter time, and fault alarm thresholds can be flexibly configured via configuration software to adapt to different on-site equipment requirements.
