Safety System Expansion Solution – TRICONEX 4000212-002 | Trident Series
The TRICONEX 4000212-002 Trident Extender is a critical chassis expansion component for the Trident Triple Modular Redundant (TMR) safety system platform. Designed for engineers who demand zero-compromise reliability in safety-instrumented systems (SIS), this extender enables seamless I/O chassis interconnection while maintaining full TMR architecture integrity.
Where This Product Is Used
The 4000212-002 Trident Extender is deployed across the most demanding safety-critical environments in industrial automation:
- Oil & Gas: Emergency Shutdown Systems (ESD) and High Integrity Pressure Protection Systems (HIPPS) on upstream wellheads, midstream pipelines, and downstream refinery units
- Petrochemical & Chemical Plants: Burner Management Systems (BMS) and process safety interlocks requiring IEC 61511 / IEC 61508 compliance
- Power Generation: Turbine protection, boiler safety, and nuclear auxiliary systems where SIL 3 certification is mandatory
- LNG & Offshore Platforms: Subsea control and topside safety systems with extended I/O requirements across multiple chassis
- Pulp & Paper / Mining: Machine safety and process interlock systems requiring high-availability TMR architecture

Application-Specific FAQ
Q: Is the 4000212-002 compatible with both Trident and Tricon systems?
A: No. The 4000212-002 is specific to the Trident TMR platform. Tricon systems use a different chassis and extender architecture. Please confirm your platform before ordering.
Q: Can this extender be installed while the system is online (hot-swap)?
A: Hot-swap capability depends on your specific Trident system configuration and firmware revision. Consult your Trident system manual or contact Konmask for guidance before attempting online replacement.
Q: What is the maximum number of chassis that can be extended in a Trident system?
A: The Trident platform supports a defined maximum I/O chassis count per main processor. Refer to the Trident System Planning Guide (document 9600-1) for your specific configuration limits.
Q: Do you provide a certificate of conformance or test report?
A: Yes. A functional test report and visual inspection certificate are available upon request for each unit shipped.
Q: Can Konmask source other Trident or TRICONEX parts not listed on the website?
A: Yes. Konmask specializes in hard-to-find industrial automation components. Submit your full BOM or part list and we will respond with availability and pricing within 24 hours.
