Core Characteristics
Built to match the TMR fault-tolerant framework of Trusted safety system with 2-out-of-3 signal voting mechanism to guarantee safety data transmission reliability; enables flexible deployment of remote I/O racks away from the main control cabinet to adapt scattered field sensor and actuator layout; supports hot-swap replacement during online system operation without triggering safety trip, reducing plant maintenance downtime; integrated comprehensive hardware self-diagnostic function to detect communication faults, bus abnormalities and module internal failures with timestamped fault recording; dedicated high-speed expansion bus maintains low-latency real-time data exchange for safety critical control signals; fully compatible with Trusted series processor modules and all standard I/O termination assemblies; front-mounted LED indicators provide direct visual feedback of module running status, communication link health and fault alarms; strict EMC design enhances anti-interference performance under complex industrial cabinet electromagnetic environments; modular plug-in structure simplifies installation, disassembly and spare part replacement; complies with IEC 61508 SIL3 certification standards for safety instrumented systems; supports flexible system topology design to expand safety control scale for medium and large process plants; realizes seamless synchronization between main controller logic and distributed remote I/O data to avoid signal delay risks for safety protection actions.
