3. Advantages and Characteristics

• Dual Redundant Power Inputs: The TRICONEX 4119A features dual independent power inputs that automatically switch to the backup source within 20ms of a primary failure, achieving a mean time between failures (MTBF) exceeding 1,000,000 hours. This redundancy reduces the risk of unplanned shutdowns caused by power interruptions by up to 95% compared to non-redundant modules.
• SIL-3 Safety Compliance: Certified to the highest safety integrity level, the module is ideal for applications where power reliability is critical, such as ESD systems in oil refineries or turbine control systems in power plants.
• Hot-Swap Capability: Faulty modules can be replaced while the system is operational, minimizing downtime during maintenance. In a chemical plant case, this feature allowed technicians to replace a faulty power supply in under 10 minutes without interrupting production, saving an estimated $200,000 in potential losses.
• Wide Input Voltage Range: Supports both AC and DC inputs, eliminating the need for separate power modules and simplifying inventory management. Its robust design withstands voltage surges and fluctuations, ensuring stable power output in unstable grid environments.
• Advanced EMI Filtering: Built-in filters reduce electromagnetic interference, protecting sensitive control components from signal distortion and ensuring reliable data transmission.

4. Application Areas and Application Cases

• Industry Applications:
  • Oil & Gas: Powers control systems in offshore platforms, refineries, and pipeline networks, ensuring continuous operation during power fluctuations.
  • Chemical Processing: Supports safety instrumented systems (SIS) and batch process controllers, where stable power is essential for preventing process upsets.
  • Power Generation: Powers turbine control systems, generator protection relays, and boiler management systems in thermal and nuclear power plants.
• Case Study:
  A large LNG processing plant in Australia integrated the TRICONEX 4119A into its ESD system to provide redundant power to 50+ I/O modules and controllers. The module’s dual input redundancy and hot-swap capability ensured uninterrupted power during a utility grid failure, allowing the system to maintain full control over critical valves and pumps. This prevented a potential shutdown that could have disrupted LNG production for hours, safeguarding an estimated $1.5 million in hourly output.

5. Competitive Comparison

Compared to similar power supply modules, the TRICONEX 4119A stands out for its combination of SIL-3 certification, dual redundancy, and wide input voltage range. While some alternatives offer basic redundancy, few match its ability to handle safety-critical applications with both AC and DC inputs in a compact form factor. Its high efficiency (92%) and advanced EMI filtering also reduce energy costs and signal interference, making it a preferred choice for industries where reliability and performance are paramount.

6. Selection Recommendations

• System Compatibility: Ensure the module is compatible with your TRICONEX control system (e.g., Tricon CX, EX) and backplane power requirements. Verify that the output voltage (24V DC) and current rating (10A) match the power needs of your I/O and controller modules.
• Power Source Requirements: Choose between AC or DC input based on your site’s power infrastructure. The module’s dual input capability is ideal for sites requiring redundant power sources (e.g., utility grid + battery backup).
• Environmental Needs: If installing in harsh environments (e.g., offshore, high-temperature zones), ensure the module’s temperature and humidity ratings align with your site conditions.
• Redundancy Strategy: For critical applications, deploy two TRICONEX 4119A modules in a redundant configuration to maximize system availability and fault tolerance.

7. Precautions

• Installation: Power down the system and use anti-static wrist straps during installation to prevent electrostatic discharge (ESD) damage. Ensure proper grounding of the module and use shielded cables for power connections to minimize EMI.
• Configuration: Use TRICONEX’s approved tools to configure power failover settings and monitor module status via the control system interface.
• Maintenance: Regularly inspect the module’s status indicators to monitor input/output voltage and current levels. Schedule firmware updates to incorporate the latest safety patches and performance optimizations.
• Troubleshooting: In the event of a power failure, replace the faulty module during a planned maintenance window or while the system is in hot-standby mode to avoid disrupting operations.
