TRICONEX 9000 Series TMR Safety Instrumented System (SIS)

Product Description: The TRICONEX 9000 series is a classic Schneider (Invensys) Tricon triple modular redundant (TMR) safety instrumented system platform, widely used for ESD emergency shutdown, fire & gas protection, burner management and turbine critical safety control. It adopts 2-out-of-3 voting logic, three independent processor channels run the same safety logic synchronously; single channel hardware failure can be isolated online without tripping the safety function, certified SIL3 by TÜV. The 9000 series includes CPU, analog/digital I/O, communication, power supply and termination modules such as 9001,9002,9100,9300 etc.

• Architecture: TMR triple redundant, hot-swap modules, online replacement without system shutdown
• Safety certification: SIL3, suitable for high-risk petrochemical, oil & gas, power plant safety loops
• Main module types: DI/DO analog AI/AO, communication interface, redundant power supply, backplane and termination assemblies
• Communication: Supports Modbus RTU, TCP/IP, Tricon peer-to-peer bus, can interlock with DCS/PLC systems
• Diagnostics: Comprehensive per-channel self-diagnosis, fault alarm and event sequence of event (SOE) recording
• Programming software: Tricon Workbench, used for logic configuration, download, force, trending and fault troubleshooting

Applications:

• Oil & gas platform, refinery ESD emergency shutdown system
• Chemical plant fire and gas detection & suppression interlock
• Thermal power plant boiler, gas turbine burner management system (BMS)
• Compressor anti-surge protection and critical machine safety control
• Legacy 9000 series SIS maintenance, spare parts replacement and retrofit

FAQ:

Q: What is the difference between Triconex 9000 series and 3000 series?
A: Both are TMR SIL3 platforms. 3000 is the earlier classic generation; the 9000 series is an upgraded version with improved diagnostic coverage, faster scan speed and updated component BOM. They are not cross drop-in compatible, backplane and firmware differ.

Q: Can modules from the 9000 series be mixed with Tricon CX?
A: No, Tricon CX is the newer generation SIS platform, hardware and firmware architecture are fully different from legacy 9000 series.

Q: Is TRICONEX 9000 still in production?
A: The Triconex 9000 series is legacy discontinued hardware. Available supply includes new old stock and fully tested refurbished spare modules.
