Functional Characteristics
1. Dual-Port TMR Redundant Communication Architecture
Two completely independent physical communication ports run simultaneously with TMR triple voting logic. Single port or single communication channel fault does not interrupt overall system data transmission. The module automatically switches to the healthy redundant port and completes fault isolation instantly.
2. Deterministic Real-Time Transmission Performance
Fixed 8 ms communication cycle, non-jitter deterministic data transmission. Fully meets strict real-time requirements of safety instrumented systems for interlock logic execution and signal transmission delay control.
3. Comprehensive Online Self-Diagnosis & Fault Transparency
Full-time monitoring of communication status, hardware circuit, power supply and link quality. Automatically locates exact fault position, records fault events and uploads diagnostic information to upper system. No manual inspection required for fault identification.
4. Complete Fail-Safe Safety Design
Strictly follows SIL3 safety logic rules. When communication failure exceeds threshold, module triggers predefined safe communication state, avoids dangerous invalid data output and ensures safety control logic stability.
5. High Anti-Interference & Isolation Performance
Adopts isolated power supply, isolated signal circuits and surge protection design. Effectively resists industrial electromagnetic interference, voltage fluctuation and field electrical noise interference. Stable operation in severe industrial electrical environments.
6. Convenient Maintenance & System Compatibility
Standard modular structure, hot-swappable design. Fully compatible with TRICONEX Trident/Tricon series safety controllers and all matching I/O modules. Simple configuration, plug-and-play integration with existing safety systems.
7. Stable Long-Term Operation Reliability
No mechanical moving parts, all solid-state circuit design. Extremely low failure rate, meets 20+ years long service life requirements of industrial safety control systems.
