Product Performance
The module is certified to IEC 61508 SIL 3, with a safety integrity level meeting signal acquisition requirements in high-risk industrial scenarios. The channel-level isolation design avoids signal interference, and a single channel fault does not affect other channels. The signal conversion response time is <1ms, which can quickly capture changes in on-site parameters, adapting to real-time control scenarios such as emergency shutdown (ESD).
It integrates channel-level diagnostic functions, which can real-time monitor faults such as open circuit, short circuit, and signal over-limit, with a diagnostic coverage of ≥99%. Fault information is uploaded to the SIS system in real time via RS-485 bus, ensuring timely handling of abnormal signals. High-precision A/D conversion chips are adopted, with conversion accuracy stable at ±0.1% in the full range, ensuring the accuracy of signal acquisition.
It supports hot swapping and modular expansion, with a maximum of 8 modules cascaded in a single system, expanding to 256 analog input channels. No shutdown is required during maintenance, adapting to 24/7 continuous production scenarios. The industrial-grade anti-EMC design ensures stable operation in high-interference environments such as frequency converters and large motors, with a Mean Time Between Failures (MTBF) ≥1,000,000 hours (25℃ environment).
