Working Principle

Four independent microprocessors split into two identical 1oo2D processing groups. Each group executes identical safety logic programs in parallel, with real-time result voting between paired processors. Cross-group data mirroring maintains identical program and signal datasets across both processing groups. Primary communication channels continuously transmit data to upper-level control systems; upon primary channel failure, secondary port activates instantaneously without data loss. All hardware faults trigger fail-safe logic state output and permanent fault log recording in redundant memory partitions.

Advantage Highlights

1. Quad-processor dual 1oo2D architecture delivers maximum fault tolerance for ultra-high-risk safety applications
2. IP54 metal housing provides superior mechanical durability and corrosion resistance compared to plastic housing modules
3. Embedded web diagnostic interface eliminates requirement for dedicated engineering laptop on-site
4. Extended temperature tolerance supports installation in unconditioned outdoor control cabinets
5. Dual redundant all communication ports ensure uninterrupted upper system data transmission
6. 16GB fault log storage enables long-term safety event traceability for regulatory compliance audits
