Yokogawa SNB10D-225/CU2T Safety Node Unit - ProSafe-RS SIS Platform
The Yokogawa SNB10D-225/CU2T is a high-integrity Safety Node Unit engineered for Safety Instrumented Systems (SIS) within the ProSafe-RS platform. This rack-mountable module delivers SIL 3-certified protection for critical process industries including oil & gas, petrochemical, power generation, and pharmaceutical manufacturing.
Technical Specifications
- Model Number: SNB10D-225/CU2T
- Configuration: Dual-redundant ESB Bus interface with CU2T topology
- Safety Integrity Level: SIL 3 (IEC 61508 / IEC 61511 certified)
- Bus Architecture: Enhanced Safety Bus (ESB) with optical fiber connectivity
- Power Supply: Dual-redundant 24V DC input for fault-tolerant operation
- Operating Temperature: -20°C to +60°C (-4°F to +140°F)
- Mounting: Standard 19-inch rack installation
- Communication Protocol: ProSafe-RS proprietary safety protocol
- Diagnostic Coverage: >99% with continuous self-diagnostics
Key Features & Benefits
- Fault-Tolerant Architecture: Dual-redundant design ensures continuous operation even during single-point failures, maximizing system availability
- Deterministic Response: Guaranteed scan cycle execution for predictable safety response times in emergency shutdown scenarios
- Hot-Swappable Capability: Replace modules without system shutdown, reducing maintenance downtime
- Integrated Diagnostics: Real-time health monitoring with automatic fault detection and alarm generation
- Scalable Configuration: Supports up to 225 I/O points per node, expandable through additional ESB bus nodes
Application Scenarios
Emergency Shutdown Systems (ESD): Deploy SNB10D-225/CU2T as the core safety controller for automated emergency shutdown sequences in refineries and chemical plants, coordinating valve closures, pump trips, and isolation procedures during hazardous conditions.
Fire & Gas Detection Systems: Integrate with multi-zone fire and gas detection networks to execute safety logic, activate suppression systems, and manage evacuation protocols with certified SIL 3 reliability.
Burner Management Systems (BMS): Control critical combustion safety interlocks for boilers, furnaces, and heaters, ensuring safe startup, operation, and shutdown sequences while preventing dangerous fuel-air mixtures.
High Integrity Pressure Protection (HIPPS): Implement overpressure protection logic to prevent catastrophic equipment failure by rapidly isolating pressure sources before relief valve activation.
System Integration Solutions
The SNB10D-225/CU2T seamlessly interfaces with Yokogawa's comprehensive ProSafe-RS ecosystem, including SSC50D safety controllers, SAI143 analog input modules, and SDV digital I/O cards. The ESB bus architecture enables distributed safety logic across multiple nodes while maintaining deterministic communication and synchronized safety responses.
Integration with CENTUM DCS platforms provides unified operator interfaces, combining process control and safety system visualization. OPC UA and Modbus TCP connectivity facilitate data exchange with third-party SCADA systems, historians, and asset management platforms.
Compliance & Certifications
- IEC 61508 SIL 3 certified (hardware and systematic capability)
- IEC 61511 compliant for process industry safety lifecycle
- ATEX/IECEx certification for hazardous area installations
- TÜV Rheinland functional safety assessment
- CE marked for European market compliance
