Key Features

1. SIL2-Certified Safety Logic Execution
   • Executes safety-critical logic per IEC 61131-3 standard languages.
   • Delivers deterministic, fault-tolerant performance for safety instrumented systems.
   • Supports online configuration and runtime reconfiguration without shutdown.
2. Dual-Redundant Fiber-Optic Ethernet Communication
   • Two independent LC fiber ports provide 10/100/1000 Mbps redundant communication.
   • Enables bumpless transfer and zero data loss during network or controller faults.
   • Facilitates peer-to-peer communication between multiple SafetyNet controllers.
3. HART Protocol Pass-Through & Diagnostic Capabilities
   • Transmits HART process variables, device status, and diagnostic data over SafetyNet.
   • Supports digital diagnostic monitoring (DDM) for fiber link health.
   • Logs up to 8000 events for audit trails and troubleshooting.
4. Intrinsic Safety & Hazardous Area Compliance
   • Certified for ATEX/IECEx Zone 0/1 and UL/cUL Division 1 hazardous locations.
   • Aluminum alloy housing provides durability and electromagnetic shielding.
   • Conformal coating option available for corrosive or humid environments.
5. Seamless System Integration & Redundancy
