It has strong fault tolerance and real-time monitoring functions and is widely used in key fields such as petroleum, chemical, power, nuclear industry, etc.

Core Features

The third mock examination redundant architecture

The processor adopts a triple design, where three independent modules run the same task simultaneously and output results through a voting mechanism to ensure that a single point of failure does not affect system operation.

Even if a module fails, the system can still maintain normal operation, greatly improving the reliability and availability of the system.

Hardware implemented fault-tolerant (HIFT) architecture

By utilizing specialized hardware and software testing mechanisms, faults can be quickly identified and responded to, ensuring stable system operation.

Support hot swappable function, allowing for the replacement of faulty modules without shutting down, reducing maintenance time and costs.

Comprehensive diagnosis and monitoring

Provide fault history records with timestamps for easy fault analysis and system maintenance.

The front panel indicator lights display the module status in real-time, making it convenient for users to quickly understand the system's operation.

Time synchronization function

Support IRIG-B002 and IRIG-B122 time synchronization signals to ensure system time is consistent with external time sources and meet high-precision time synchronization requirements.

communication interface
