Core Product Features
3.1 Upgraded TMR Fault-Tolerant Safety Architecture
The 9000 Series inherits and upgrades the mature industrial TMR triple redundant architecture, with three completely independent and synchronous operating control channels. Through hardware 2-out-of-3 voting mechanism, it automatically isolates and shields single-channel faults, realizing non-stop operation of the system in case of single-point failures such as processor abnormality, module damage and signal deviation. The upgraded algorithm optimizes signal judgment accuracy and response speed, completely eliminating system single-point failure risks and ensuring zero misoperation and zero refusal of safety logic.
3.2 Ultra-High Safety Integrity & Availability
Supporting dual certification of SIL 3 and SIL 4 safety integrity levels, the 9000 Series meets the most stringent safety standard requirements of global process industries. The system adopts full-link fault tolerance design from power supply, processor, bus to I/O channels, effectively reducing safety loop failure probability. It maintains ultra-high system availability during long-term industrial operation, avoids production shutdown losses caused by safety system faults, and balances safety guarantee and production efficiency perfectly.
