Note: Cross-brand replacements require full system re-validation per IEC 61511. Contact our technical team for migration support.

Why Choose the Original T8448 Model

Proven TMR Architecture: Hardware fault tolerance with 2-out-of-3 voting logic ensures no single-point failure causes a spurious trip or dangerous state.
SIL 3 Certified: Independently certified to IEC 61508 SIL 3, meeting the most stringent functional safety requirements.
Seamless System Integration: Designed exclusively for the Trusted chassis ecosystem — no re-engineering required for like-for-like replacement.
Long Field Track Record: Deployed globally in oil & gas, petrochemical, and power generation facilities for over two decades.
Minimized Validation Effort: Using the original part number preserves existing safety case documentation and reduces re-qualification cost.

Typical Applications

Emergency Shutdown Systems (ESD) in oil & gas platforms and refineries
Burner Management Systems (BMS) in power generation
High-integrity pressure protection systems (HIPPS)
Turbine and compressor control safety layers
Chemical and petrochemical process safety instrumented systems (SIS)
Nuclear auxiliary safety systems

Selection Guide

Use the following criteria to determine whether the T8448 is the correct module for your application:

Existing Trusted TMR system? → T8448 is the direct fit. No chassis modification needed.
Need SIL 3 compliance? → T8448 is SIL 3 certified. Confirm your SIL target with your functional safety engineer.
24VDC field wiring? → T8448 matches. For 120VAC or 240VAC field devices, consult alternative ZIM variants.
Replacing a failed module? → Match the exact part number and firmware revision. Contact us with your chassis serial number for verification.
Planning a system upgrade? → Consider Rockwell Automation’s Trusted migration path or a full GuardLogix SIL 3 migration for long-term support.
Spare parts stocking? → We recommend holding 1–2 spare T8448 units per critical loop. Contact us for volume pricing.

Replacement & Compatibility FAQ

Q: Can I replace T8448 with T8448A?
A: In most cases yes, but verify firmware revision compatibility with your Trusted system version. Contact us for a compatibility check.

Q: Is the T8448 still in production?
A: ICS TRIPLEX (now part of Rockwell Automation) has transitioned some Trusted series modules to end-of-life. We maintain surplus stock. Contact us for availability.

Q: Can I use a T8448 in a non-Trusted chassis?
A: No. The T8448 is designed exclusively for the Trusted TMR chassis backplane and is not compatible with other PLC or DCS platforms without a full system redesign.

Q: What is the warranty on your T8448 units?
A: We offer a 12-month warranty against manufacturing defects on all units supplied. Extended warranty options available on request.

Q: Do you provide installation support?
A: Yes. Our technical team can provide remote commissioning guidance and documentation review. Contact support@konmask.com.
