Product Performance

Adopting a Triple Modular Redundancy (TMR) architecture with three independent microprocessors, it ensures continuous system operation without interruption in case of a single point failure, as the other two channels can work normally and automatically shield the faulty channel when any channel malfunctions.

Compliant with IEC 61508 SIL3 Safety Integrity Level requirements and certified by international authoritative organizations such as TÜV and FM, it achieves the highest safety performance standard in industrial safety control, suitable for critical safety loops including Emergency Shutdown (ESD) and Fire & Gas (F&G) detection systems.

Designed with 32 digital input channels, commoned in groups of 8, it meets the demand for large-scale industrial field signal acquisition. Electrical isolation between channels effectively prevents signal interference and ensures the accuracy of data collection.

Equipped with built-in self-test and fault diagnosis functions with a diagnostic coverage rate of ≥99%, it can real-time monitor the hardware status of the module (power supply, channel faults), support fault alarms and status indication, and intuitively display the input status of each channel and the overall operation of the module through LED indicators.

Supporting hot-swappable operation, the module can be replaced online without affecting system operation, significantly reducing maintenance time, improving equipment availability and minimizing downtime losses.

The built-in input filtering and restoration functions can automatically process on-site interference signals, ensuring the stability of input signals, reducing the workload of the main processor and improving the overall response speed of the system.

With an operating temperature range of -40°C to +70°C and strong anti-electromagnetic interference capability, it can operate stably in harsh industrial environments such as high dust, humidity and vibration with an extremely low failure rate.

Compatible with the TriBus triple redundant dedicated bus, it enables fast data transmission with low latency, seamless communication with the main processor module of the Tricon system, supports conversion of multiple industrial communication protocols, and has strong adaptability.

Manufactured with industrial-grade components, it features a robust structure and long service life, equipped with overvoltage and overcurrent protection functions to prevent module damage and ensure safe system operation.
