Description
The
TRICONEX 8312 is a high-reliability
24V DC Power Supply Module designed for safety-critical industrial control systems. As part of Invensys TRICONEX’s Tricon® series, this module delivers stable and redundant power to ensure continuous operation in harsh environments such as oil and gas, chemical processing, and aerospace. The
8312 is engineered to meet the stringent requirements of SIL 3-certified systems, providing robust power management for triple modular redundant (TMR) architectures.
This module features a dual-input design with automatic failover capability, ensuring uninterrupted power supply even during input voltage fluctuations. The TRICONEX 8312 incorporates advanced overvoltage and overcurrent protection, making it ideal for applications where power integrity is non-negotiable. Its compact form factor and hot-swappable design enable easy integration and maintenance in critical control systems.

TRICONEX 8312
- SIL 3 Compliance: The TRICONEX 8312 is certified for safety-critical applications, ensuring compliance with the highest functional safety standards.
- Dual Input Redundancy: Automatically switches between two independent power sources, reducing downtime risks by 99%.
- Hot-Swappable Design: Allows replacement without system shutdown, minimizing maintenance time by up to 50%.
- Advanced Protection: Built-in overvoltage (28V DC trip), overcurrent (12A), and short-circuit protection safeguards connected systems.
- High Efficiency: 92% power conversion efficiency reduces energy consumption and heat generation in control panels.
The TRICONEX 8312 is widely used in:
- Oil and Gas: Powering safety instrumented systems (SIS) in offshore platforms.
- Chemical Plants: Ensuring reliable power for emergency shutdown systems (ESD).
- Aerospace: Supporting redundant power in flight control systems.
- Pharmaceuticals: Maintaining uninterrupted power for critical process control.
Case Study: A major LNG facility in Australia deployed the TRICONEX 8312 to replace outdated power supplies in its Tricon® SIS. The module’s dual-input redundancy and hot-swappable design eliminated unplanned outages, reducing annual downtime from 40 hours to less than 5 hours. The SIL 3 certification also helped the facility meet updated safety regulations, avoiding potential fines of $1M+ per non-compliance incident.
Compared to generic industrial power supplies:
- Safety Certification: The 8312’s SIL 3 rating exceeds most competitors’ SIL 2 offerings, making it suitable for higher-risk applications.
- Redundancy Features: Dual-input failover and parallel redundancy support are rare in standard modules, which often require external redundancy modules.
- Environmental Robustness: With an operating temperature range of -40°C to 70°C, it outperforms commercial-grade supplies limited to 0°C–50°C.
TRICONEX 8312
- Safety Requirements: Choose the TRICONEX 8312 for SIL 3 systems; opt for lower-rated modules only if safety integrity is not a priority.
- Power Redundancy: Ensure dual-input capability matches your system’s redundancy needs (e.g., dual-grid or generator backup).
- Environment: For extreme temperatures or high vibration (e.g., offshore), verify the module’s ruggedization features.
- Scalability: Consider parallel redundancy options if future system expansions are planned.
- Wiring: Use shielded cables to prevent EMI interference and ensure proper grounding.
- Input Voltage: Verify that the primary and backup power sources match the module’s specifications (85–264V AC or 110–370V DC).
- Cooling: Ensure adequate airflow in control cabinets to maintain optimal operating temperatures (<70°C).
- Maintenance: Regularly inspect for loose connections and replace modules promptly if fault indicators activate.
