Compatible Replacement & Equivalent Models
When the TRICONEX 4400 is unavailable or end-of-life, the following models may serve as functional replacements or equivalents depending on your system revision and firmware version. Always verify compatibility with your system integrator before substitution.
- TRICONEX 4351B – Enhanced communication module, backward-compatible in select Tricon chassis configurations
- TRICONEX 4352B – Dual-port network communication, suitable for redundant network topologies
- TRICONEX 4409 – Advanced communication module with expanded protocol support
- TRICONEX 4100 – Legacy communication module; verify chassis slot and firmware compatibility
- TRICONEX 4119A – Alternative for older Tricon v9/v10 systems
Note: Replacement suitability depends on Tricon chassis version, firmware revision, and network topology. Contact Konmask for a compatibility assessment.
Why Choose the Original Model
- Validated SIL 3 Performance: The 4400 is factory-validated within the Triconex TMR architecture, ensuring full SIL 3 integrity without re-validation overhead.
- Seamless Integration: Drop-in replacement for existing Tricon systems with no firmware changes required in most configurations.
- Proven Field Reliability: Deployed globally in mission-critical SIS applications with documented MTBF performance.
- OEM Support Path: Retains eligibility for Schneider Electric / Triconex OEM support contracts and lifecycle services.
- Regulatory Compliance: Maintains existing system safety case documentation without re-certification.
Typical Applications
- Emergency Shutdown Systems (ESD) in oil & gas upstream/downstream facilities
- Burner Management Systems (BMS) in power plants and refineries
- High-Integrity Pressure Protection Systems (HIPPS)
- Compressor and turbine safety control
- Chemical and petrochemical process safety interlocks
- Nuclear auxiliary safety systems (where applicable)
System Compatibility
- Compatible Platforms: Tricon v9, v10, v11 Safety Systems
- Chassis Types: Tricon 8-slot and 16-slot main chassis
- Engineering Software: TriStation 1131 v4.x and above
- Network Interfaces: Compatible with plant DCS, SCADA, and historian systems via standard industrial protocols
- Not Compatible With: Trident or Tri-GP platforms (different module form factor)
Selection Guide
Use the following criteria to determine whether the TRICONEX 4400 or an alternative model is the right choice for your application:
- Step 1 – Identify your Tricon chassis version (v9 / v10 / v11) from the chassis nameplate or TriStation project file.
- Step 2 – Confirm slot assignment – Communication modules occupy designated slots; verify the 4400 is specified in your I/O map.
- Step 3 – Check firmware revision – Ensure the module firmware is compatible with your TriStation 1131 project version.
- Step 4 – Evaluate network protocol requirements – If dual-port or expanded protocol support is needed, consider the 4352B or 4409 as alternatives.
- Step 5 – Assess lifecycle status – If the 4400 is end-of-life in your region, Konmask can source tested surplus units or recommend a validated upgrade path.

Replacement & Compatibility FAQ
Q: Can I replace the TRICONEX 4400 with a 4352B without re-validation?
A: In many cases, yes — if the chassis firmware and TriStation project are compatible. However, any hardware change in a SIL-rated system should be reviewed by your functional safety engineer. Konmask can provide technical documentation to support your MOC (Management of Change) process.
Q: Is the 4400 still in production?
A: The TRICONEX 4400 may be at end-of-life or limited availability from OEM channels. Konmask specializes in sourcing tested surplus and new-surplus units to support legacy system maintenance.
Q: What is the difference between the 4400 and the 4409?
A: The 4409 is a later-generation communication module with expanded protocol support and improved diagnostics. It may require firmware updates and configuration changes. Contact us for a detailed comparison.
Q: Do you provide a certificate of conformance (CoC)?
A: Yes. A CoC and inspection report are available upon request for all units shipped from Konmask.
Q: Can you source multiple units for a plant-wide spares program?
A: Yes. Konmask supports bulk procurement and consignment stocking programs. Contact us for volume pricing.
