Description
Functional Features
- Triple Modular Redundancy (TMR): Each channel is triple-redundant, with three independent processing paths for fault detection and correction.
- Self-Diagnostics: Continuous monitoring of internal circuitry for fault detection (e.g., open circuit, short circuit, signal deviation).
- Hot Swap Capability: Modules can be replaced without powering down the system, minimizing downtime.
- Sequence of Events (SOE) Reporting: Provides high-resolution timestamped data for fault analysis and system diagnostics.
- Isolated Power Groups: Output channels are organized into 8 isolated power groups, preventing faults in one group from affecting others.
- High Noise Immunity: Designed to operate reliably in environments with electromagnetic interference (EMI) or electrical noise.
- Health Status Indicators: LED indicators on the front panel display module health and fault conditions.
Application Scenarios
- Power Generation: Used in nuclear, thermal, and renewable power plants for turbine control, generator protection, and grid stability monitoring.
- Oil & Gas: Monitors safety-critical signals in upstream, midstream, and downstream operations, such as emergency shutdown (ESD) systems and fire & gas detection.
- Chemical Processing: Ensures safe operation of hazardous processes by monitoring valves, pumps, and sensors in reactors and distillation columns.
- Water Treatment: Applied in wastewater treatment plants for pump control and level monitoring.
- Transportation: Used in railway signaling systems and airport baggage handling for fault-tolerant control.
Advantages
- High Reliability: TMR architecture ensures no single point of failure, achieving > 99.999% availability.
- Safety Certified: Complies with stringent safety standards (e.g., IEC 61508 SIL 3) for use in critical applications.
- Scalability: Supports modular expansion to meet system requirements.
- Easy Maintenance: Hot-swappable design reduces maintenance time and cost.
- Comprehensive Diagnostics: Provides detailed fault information for quick troubleshooting and system optimization.
