Certification: CE, UL, SIL3, ATEX/IECEx (non-explosion-proof area)

III. Key Functional Features

Hardware Redundant Safety Architecture: Dual-channel processor for real-time comparison, single-channel failure does not affect safe operation, meeting SIL3 fault-tolerant requirements.

Full Diagnostic Coverage: Real-time self-check of power supply, clock, memory, I/O interface, communication link, fault automatic alarm and safe shutdown.

Strong Real-time Logic Processing: Supports complex safety logic (ESD interlock, BMS flameout protection, F&G shutdown), compatible with HIMA ProSafe programming software.

Redundancy and Expansion Capability: Supports dual-machine hot standby (redundant), can expand remote I/O (such as H41q series modules), build distributed SIS system.

Long Life and High Reliability: MTBF ≥ 1500,000 hours, design life 15 years, suitable for harsh environments such as petrochemical, power, and metallurgy.
