working principle
Stage description
The input stage module receives on-site sensor/switch signals → through photoelectric isolation → AD/DA conversion → digital signals are uploaded to the Safety Manager
During the output phase, the Safety Manager issues control commands → digital signals → DO drives → drives on-site actuators (relay/transistor outputs)
The safety monitoring system has built-in self diagnostic function, which automatically triggers safety actions in case of faults and reports detailed diagnostic information through LONWorks
core advantage
Advantages Explanation
🔒 High safety level SIL 3/Cat.4/PL e, meeting the strictest functional safety requirements
🔧 Flexible and configurable 32 channel DI/DO/AI combination to meet different on-site needs
🌐 HART supports direct access to HART smart meters without the need for an additional gateway
🛡️ Electrical isolation between channels and systems, with strong anti-interference ability
📊 Remote diagnosis through Safety Builder for real-time monitoring and fault location
