Compatible Replacement & Equivalent Models
When the 3008N is unavailable or end-of-life, the following models may serve as functional replacements or equivalents depending on your system revision and configuration. Always validate compatibility with your system integrator before substitution.
- TRICONEX 3008 – Earlier revision of the same analog input main processor; functionally equivalent in most Tricon v9/v10 chassis configurations.
- TRICONEX 3007 – Analog Input Expander Processor; used in conjunction with the main processor for expanded channel counts.
- TRICONEX 3006 – Digital Input Main Processor; consider when migrating signal types or redesigning I/O architecture.
- TRICONEX 3009 – Analog Output Main Processor; paired with 3008N in closed-loop control applications.
- TRICONEX 3664 – Enhanced Analog I/O module for newer Tricon CX platforms; evaluate for system upgrade paths.
Important: Replacement modules must match firmware revision, chassis slot assignment, and TMR configuration. Consult Konmask technical support for pre-purchase compatibility verification.
Why Choose the Original Model
- SIL 3 Integrity: The 3008N is engineered and certified for use in Safety Instrumented Systems (SIS) requiring the highest safety integrity levels.
- TMR Architecture: Triple redundancy ensures fault tolerance and continuous operation even with single-module failures — critical for uninterrupted plant safety.
- Proven Field Record: Deployed globally in refineries, LNG terminals, and power plants with decades of operational history.
- OEM Firmware Compatibility: Original modules guarantee seamless integration with Triconex TriStation 1131 programming environment without firmware conflicts.
- Regulatory Compliance: Meets IEC 61508, IEC 61511, and relevant functional safety standards required by most EPC contractors and end-users.
Typical Applications
- Emergency Shutdown Systems (ESD) in oil & gas upstream and downstream facilities
- Burner Management Systems (BMS) in fired heaters and boilers
- High Integrity Pressure Protection Systems (HIPPS)
- Compressor and turbine control and protection
- LNG liquefaction and regasification plant safety systems
- Nuclear auxiliary safety instrumentation (where applicable)
- Chemical and petrochemical process safety interlocks
System Compatibility
The TRICONEX 3008N is designed for use within the Tricon TMR platform. Confirm the following before ordering:
- Chassis Version: Compatible with Tricon v9 and v10 chassis; verify slot type (main vs. expander).
- TriStation Version: Ensure your TriStation 1131 software version supports the 3008N module library.
- Firmware Revision: Match module firmware to existing installed base to avoid version conflicts.
- Power Budget: Confirm chassis power supply capacity accommodates the module’s draw alongside existing I/O load.
- TMR Slot Pairing: The 3008N must be installed in all three TMR legs simultaneously for proper redundancy operation.
Selection Guide
Use the following decision framework to select the correct analog input module for your Tricon system:
- Need analog input on a main slot? → Select 3008N (this module).
- Need to expand analog input channels beyond main slot capacity? → Add 3007 Expander Processor.
- Migrating to Tricon CX platform? → Evaluate 3664 or consult Schneider Electric for migration path.
- Replacing a failed 3008 (non-N revision)? → The 3008N is the direct upgrade; confirm chassis and firmware compatibility.
- Unsure of revision or slot type? → Provide your chassis serial number and slot diagram to Konmask for a verified recommendation.

Replacement & Compatibility FAQ
Q: Can the 3008N replace a 3008 directly?
A: In most cases yes, as the 3008N is the revised version of the 3008. However, firmware and chassis slot compatibility must be verified. Contact us with your system details for confirmation.
Q: Is the 3008N compatible with Tricon CX?
A: The 3008N is designed for the classic Tricon TMR platform. Tricon CX uses a different I/O architecture. Consult Schneider Electric or Konmask for CX-compatible alternatives.
Q: Can I use a single 3008N in a TMR system?
A: No. TMR systems require the module to be installed in all three legs simultaneously. Single-module installation will result in a system fault.
Q: What is the difference between the 3008 and 3008N?
A: The “N” designation typically indicates a revised or enhanced version with improved diagnostics or updated component specifications. Verify with the module label and TRICONEX documentation for your specific revision history.
Q: Do you provide warranty on used modules?
A: Yes. Tested used and refurbished modules carry a 90-day functional warranty. New/surplus units carry a 12-month warranty. Terms available on request.
