Product Performance

Communication Performance: Equipped with single-mode optical fiber communication interface and multiple interfaces including Ethernet and RS-485, supporting a maximum long-distance transmission of 12km, with redundant communication links. It can automatically switch to the standby channel when a single link fails, with strong anti-interference ability and stable transmission rate, supporting multiple communication protocols, ensuring real-time and accurate data transmission between the main controller and remote sites, and guaranteeing the coordinated operation of the system.

Adaptability Performance: Specifically designed for the TRICONEX TMR fault-tolerant Safety Instrumented System, it can be seamlessly integrated into TRICONEX Tricon, Trident and other safety control systems, supporting 3 remote site connections, scalable to 32 I/O modules and 32 I/O points, supporting multiple I/O signal types, supporting hot-swapping function, and allowing online module replacement without interrupting production operations, adapting to industrial control scenarios of different scales.

Safety Performance: Adopts the TMR redundancy design concept, meets SIL 3 safety integrity requirements, complies with IEC61508 and IEC61511 standards, has complete fault tolerance, and a single component failure will not affect the normal operation of the module. It can effectively protect the safe and stable operation of the system and associated on-site equipment, adapting to various safety-critical application scenarios.

Stability Performance: Uses industrial-grade high-quality components with strong wide-temperature adaptability, ensuring long-term stable operation in the range of -40℃ to +70℃ without frequent faults. The protection class reaches IP20, with good vibration resistance and anti-interference performance, which can meet the long-term continuous operation needs of harsh industrial environments.

Operation and Maintenance Performance: Modular structure design enables easy installation and disassembly, supports online module replacement and maintenance. Equipped with complete built-in fault diagnosis function, combined with multiple groups of diagnostic indicators, it can quickly locate fault points, facilitating timely troubleshooting and problem solving. It supports configuration with TriStation 1131 software and is matched with special debugging tools to reduce daily operation and maintenance costs and improve operation and maintenance efficiency.
