ICS Triplex T9300

Core Features & Customer Value

Triple Modular Redundant Architecture: The T9300 backplane supports the Trusted TMR system’s triple modular redundancy technology, which incorporates three independent channels for each I/O point. This design provides fault tolerance by ensuring continuous operation even if one channel fails, minimizing downtime and data loss. For engineering teams, this architecture means that a single component failure will not compromise the entire safety system, maintaining operational integrity while alerting maintenance personnel to the need for repair. This capability is particularly valuable in continuous process industries where unplanned shutdowns can result in significant production losses and safety risks.

High Availability and Fault Tolerance: The backplane is engineered to maintain system functionality during hardware failures through redundant power supply support and comprehensive diagnostic capabilities. The dual bus architecture optimizes data transfer and enhances system reliability by providing two independent I/O buses. For system integrators, this design reduces the risk of single points of failure and simplifies system design by eliminating the need for complex redundancy schemes. The comprehensive diagnostics enable rapid fault identification and isolation, reducing mean time to repair and improving overall system availability.

Scalable and Flexible Configuration: The T9300 supports up to 24 I/O modules, providing significant expansion capability for growing system requirements. The modular design allows for flexible system configuration based on specific I/O needs, with support for a broad range of digital and analog I/O modules. The backplane can be expanded using the T9310 expansion cable, enabling additional rows of I/O base units without requiring major system redesign. This scalability allows engineering teams to start with a basic configuration and expand as process requirements evolve, reducing initial capital investment while maintaining future flexibility.

Advanced Communication Capabilities: The backplane supports multiple high-speed communication protocols including Modbus RTU, EtherCAT, and Profinet, ensuring efficient data transmission and real-time performance. This multi-protocol support enables seamless integration with various control systems and field devices, reducing integration complexity and improving system interoperability. The high-speed communication capabilities ensure that critical process data is transmitted with minimal latency, supporting time-sensitive safety functions and process control applications.

Robust Industrial Design: Constructed with high-quality materials, the T9300 is rated for operation in a wide temperature range (-20°C to +60°C) and is suitable for deployment in harsh industrial environments. The backplane’s robust construction and IP-rated protection ensure reliable operation in environments with dust, moisture, and electrical noise. For plant operators, this durability translates to reduced maintenance requirements and extended service life, lowering the total cost of ownership over the system’s operational lifetime.

Typical Applications

The ICS Triplex T9300 is predominantly deployed in safety instrumented systems (SIS) and emergency shutdown (ESD) systems within hydrocarbon processing facilities. In offshore production platforms, it typically serves as the I/O backbone for critical safety functions, interfacing with emergency shutdown valves, pressure switches, and fire and gas detection systems. The backplane’s high availability and fault tolerance make it suitable for the space-constrained and environmentally challenging conditions typical of offshore installations, where reliability is paramount due to limited access for maintenance and the potential consequences of system failure.

In refinery and petrochemical applications, the T9300 is commonly specified for fire and gas detection systems, where it provides the I/O infrastructure for monitoring gas detectors, flame detectors, and smoke detectors. The SIL 3 certification ensures compliance with safety integrity requirements for such critical functions, while the backplane’s comprehensive diagnostics enable proactive maintenance and early detection of developing issues. The module’s 1ms Sequence of Events (SOE) resolution provides precise timing information for event analysis, which is essential for investigating process upsets and safety system activations.

The backplane also finds application in power generation plants, particularly combined-cycle and nuclear facilities, where it provides the I/O interface for safety-related field devices in turbine protection systems and reactor protection systems. The wide operating temperature range allows deployment in unmanned remote locations with varying environmental conditions, while the configurable digital filtering eliminates field-induced noise, ensuring reliable operation in electrically noisy industrial environments. In these applications, the T9300’s scalability enables the system to accommodate additional I/O points as plant modifications or expansions occur, supporting long-term operational flexibility.
