TRICONEX 4351A
The Triconex 4351A is a module from the Tricon safety instrumented system (SIS) by Schneider Electric (formerly Triconex). It is part of the Tricon v9–v11 series and serves as a communication module or I/O module, depending on the configuration.
Key Technical Parameters of Triconex 4351A:
1. Function:
- Acts as a communication module (e.g., for Modbus, TriStation communication) or specialized I/O module in a Tricon system.
- Supports redundant communication for high availability.
2. Compatibility:
- Works with Tricon v9, v10, and v11 systems.
- Interfaces with Tricon Main Processors (MPs) and other I/O modules.
3. Communication Protocols:
- Supports TriStation protocol (for Triconex engineering software).
- May support Modbus RTU/TCP (depending on firmware).
- Optional Ethernet or serial communication (varies by model).
4. Power Requirements:
- Typically operates on 5V DC (supplied via the Tricon backplane).
- Power consumption: Low to moderate (exact specs depend on configuration).
5. Environmental Ratings:
- Operating Temperature: -40°C to +70°C (-40°F to +158°F).
- Humidity: 5% to 95% (non-condensing).
- Certifications: Compliant with IEC 61508 (SIL 3) for safety systems.
6. Redundancy & Fault Tolerance:
- Supports Triple Modular Redundancy (TMR) for high reliability.
- Automatic fault detection and failover.
7. Physical Dimensions & Mounting:
- Standard Tricon module size (fits in a Tricon chassis).
- Hot-swappable (in most configurations).
Applications:
