Safety Shutdown & SIS Solution — TRICONEX SDO3411 | TMR Series
Where This Product Is Used
The TRICONEX SDO3411 Safety Digital Output Module is purpose-built for Safety Instrumented Systems (SIS) operating under IEC 61511 and IEC 61508 SIL 3 requirements. It is widely deployed in:
- Oil & Gas: Emergency Shutdown (ESD) systems on offshore platforms, onshore terminals, and pipeline SCADA stations
- Petrochemical & Refining: Burner Management Systems (BMS), high-integrity pressure protection systems (HIPPS)
- LNG & Gas Processing: Compressor and turbine trip logic, fire & gas detection output actuation
- Power Generation: Turbine protection, boiler safety interlock output control
- Chemical Plants: Reactor safety shutdown, toxic release prevention systems
- Nuclear Auxiliary Systems: Non-nuclear safety-class auxiliary control where TMR architecture is mandated

Application-Specific FAQ
Q: Is the SDO3411 compatible with the Tricon v9 and v10 chassis?
A: Yes. The SDO3411 is compatible with Tricon v9.x and v10.x main chassis platforms. Always verify firmware revision compatibility with your TriStation 1131 version before installation.
Q: Can the SDO3411 be used in a SIL 3 loop without additional redundancy?
A: Yes. The TMR architecture of the SDO3411 inherently achieves SIL 3 capability as a standalone module, subject to the overall SIL verification of the complete safety loop per IEC 61508.
Q: What is the difference between SDO3411 and SDO3401?
A: The SDO3411 is a later-generation module with enhanced diagnostics and higher channel density. The SDO3401 is an earlier variant; both are TMR digital output modules but are not directly interchangeable without engineering review.
Q: Do you supply the matching Field Termination Assembly (FTA)?
A: Yes. Contact us with your chassis slot configuration and we can recommend and supply the correct FTA for the SDO3411.
Q: Can I get a test report or functional test certificate?
A: Functional test reports are available upon request for an additional fee. Please specify this requirement when submitting your RFQ.
