Triconex 3008 | Main Processor Module | TMR Safety Controller

Product Description

Overview

The Triconex 3008 Main Processor Module is a high-performance controller core for Tricon™ TMR (Triple Modular Redundancy) systems, version 9.6 and later. Designed for SIL 3 safety applications, it executes user-defined control programs, manages I/O communication, and performs critical voting functions. Each module operates independently yet synchronizes seamlessly with two other MPs to maintain system availability, even during component failures.

Key Features

Triple Redundancy and Voting
The 3008 MP forms part of a TMR set, connecting with other modules via the proprietary TriBus. Logic results and digital inputs are compared across all three modules, ensuring that any single module failure does not compromise system integrity.

High-Performance Processing and Memory

• 32-bit microprocessor capable of high-speed execution of complex safety logic

• 16 MB Flash memory for program storage

• Battery-backed 32 KB SRAM for retentive data

• 6 MB Flash PROM for operating system and fault analysis

Advanced Diagnostics and Fault Tolerance

• Self-diagnostic routines for CPU, memory, and peripheral integrity

• Watchdog timers to detect and isolate malfunctioning logic

• Online diagnostics to identify transient faults and I/O errors

Hot-Swap Capability and Online Updates

• Faulty modules can be replaced without shutting down the system

• Automatic memory synchronization for new modules

• Supports online logic updates and configuration changes

Communication and Synchronization

• Manages dual-redundant I/O buses and up to 15 expansion chassis

• TriBus communication for high-speed inter-MP data exchange

• Network communication module ensures precise time synchronization for event logging

Technical Specifications

Applications

The Triconex 3008 is ideal for high-integrity industrial control systems, including:

• Emergency Shutdown Systems (ESD)

• Burner Management Systems (BMS)

• Fire & Gas (F&G) Systems

• High-Integrity Pressure Protection Systems (HIPPS)

FAQ

Q: Can the 3008 module be replaced while the system is running?
A: Yes, hot-swap functionality allows seamless replacement without process interruption.

Q: Is the 3008 compatible with older Tricon systems?
A: It supports Tricon v9.6 and newer. It can replace 3006 or 3007 modules to improve memory and processing capabilities.

Q: How does the 3008 ensure fault tolerance?
A: Using Triple Modular Redundancy (TMR), any disagreement between the three MPs is resolved via majority voting, and the faulty module is flagged.
