Functional Characteristics
1. Ultimate TMR Triple Redundancy Reliability
Three completely independent control circuits collect, calculate and output signals simultaneously. Cross majority voting logic eliminates single channel failure influence. Single module or single channel fault will not cause system control failure or safety function loss.
2. Full-range On-line Self-diagnosis & Fault Isolation
Real-time monitoring of output channel status, power supply, bus communication and hardware circuit. Automatically locate faulty channel, isolate fault output and send alarm signal. Normal channels keep working continuously.
3. Complete Fail-safe Safety Design
Strictly comply with safety instrumented system logic. When module detects abnormal fault, output automatically switches to predefined safe state immediately. Effectively avoid dangerous false output in industrial high-risk scenarios.
4. High Stability Anti-interference Performance
Adopt isolated power supply, isolated signal circuit and anti-surge protection circuit. Effectively resist industrial electromagnetic interference, voltage fluctuation and harsh on-site electrical noise.
5. Convenient Maintenance & High Scalability
Modular standardized structure, hot pluggable design. Support free expansion matching with TRICONEX Trident/Tricon series controllers. Simple wiring, convenient configuration and on-site debugging.
6. Precise Monitored Output Control
Each output channel has independent status feedback monitoring. Realize closed-loop verification of output execution status, ensure consistent output instruction and on-site equipment action.
