Selection Suggestions and Precautions

Selection Suggestions:

Use a single T9110 for non-safety or low-integrity applications (up to SIL 1).
Deploy two processors for SIL 3 safety applications.
Deploy three processors for full TMR fault-tolerant SIL 3 operation with highest availability.
Confirm compatibility with AADvance base units (T9100 / T9101) and I/O modules.
Pair with appropriate AADvance Workbench or Trusted SIS Workstation software for programming.

Precautions:

Must be installed on the correct AADvance processor base unit.
Power supply must be within 18–32 V DC range; redundant power is recommended.
When the system degrades to 1oo1D, faulty modules should be replaced within the assumed Mean Time To Repair (MTTR) to maintain safety integrity.
Follow Rockwell Automation / ICS Triplex installation, grounding, and configuration guidelines.
Use only approved software tools and firmware versions for configuration and maintenance.
This is a safety-critical component — proper validation, proof testing, and documentation are required for SIL applications.
