Product Performance
- High safety integrity：Adopts an independent safety processor and dedicated safety kernel, completely isolated from standard control functions, ensuring that safety functions are not affected by non-safety code, meeting the strict requirements of SIL 3 and PL e.
- Redundant design：Supports dual-module redundant configuration. When the main module fails, the standby module can switch seamlessly, ensuring continuous operation of safety functions and improving system availability.
- Fast response capability：The processing time of safety instructions is ≤10ms, which can quickly respond to safety-related input signals, trigger protection actions in time, and reduce the possibility of accidents.
- Safety communication：Realizes encrypted communication with other safety devices through the safety Ethernet interface, preventing data tampering or interference, and ensuring the integrity and confidentiality of safety information transmission.
- Comprehensive diagnostic functions：Equipped with comprehensive self-diagnosis and external fault diagnosis capabilities, it can monitor module hardware status, communication links and safety input/output signals in real time, feedback fault information through indicators and communication interfaces, facilitating quick troubleshooting.
