Triconex 9802 Tricon TMR Main Processor Module

Product Overview

The Triconex 9802 (MP3008) operates as the central intelligence hub for the Triconex safety system. This Main Processor executes complex application programs and system logic while managing the specialized Triple Modular Redundancy (TMR) architecture. It processes field data through three independent paths, ensuring the safety loop remains active even during a hardware fault. We supply this module exclusively as 100% Brand New and Original factory-sealed equipment.

Technical Specifications

Engineering Advantages

• Hardware-Based Voting Logic: The 9802 utilizes three identical processing sub-systems that execute logic simultaneously. The internal voting circuitry compares the results in real-time. If one processor reports a discrepancy, the two healthy processors out-vote the failed unit, preventing nuisance trips and ensuring zero-down-time process availability.

• Data Integrity via NVRAM: The 16 MB non-volatile RAM stores critical system states and user-defined application logic. This memory architecture protects against data loss during total power failure, allowing the controller to resume safe operation immediately upon power restoration without requiring a full manual reload.

• Dual RISC Performance: The dual RISC processor design delivers high-speed calculation cycles for time-sensitive safety applications. This computational power supports extensive logic matrices required for complex Emergency Shutdown (ESD) and Fire and Gas (F&G) protection without compromising scan times.

• Flexible Network Integration: Integrated Ethernet and RS-485 ports facilitate high-speed data exchange with DCS (Distributed Control Systems) and SCADA platforms. This connectivity allows engineers to monitor safety system health and diagnostic alarms across the plant network without impacting the dedicated safety bus.

FAQs

• Is the Triconex 9802 interchangeable with the MP3008?

  Yes. The 9802 and MP3008 represent the same technical specification within the Tricon system. They share identical form factors and logic processing capabilities, allowing for direct replacement in existing Tricon chassis.

• How does the TMR architecture handle a single processor fault?

  The system identifies the faulting processor immediately via internal diagnostics. The 9802 then transitions to a "dual" mode logic where the two remaining processors maintain control. A front-panel "Fault" LED illuminates, notifying maintenance teams to replace the module while the process remains fully operational.

• What are the environmental requirements for the 16MB NVRAM?

  The NVRAM requires no external battery for short-term data retention. However, for long-term storage or deployment in high-temperature environments, ensure the control cabinet maintains stable airflow to preserve the integrity of the solid-state memory components.
