Compatible Replacement & Equivalent Models
When the TRICONEX 3624 is unavailable or end-of-life, the following modules may serve as functional replacements or equivalents depending on your system revision and firmware version. Always consult your system integrator or Triconex-certified engineer before substitution.
- TRICONEX 3625 — Enhanced Supervised DO module; direct functional upgrade with additional diagnostics. Recommended first-choice replacement.
- TRICONEX 3603E — Digital Output module for Tricon systems; verify channel count and supervision requirements.
- TRICONEX 3604E — Alternative DO module; confirm backplane slot compatibility.
- TRICONEX 3623 — Earlier-generation Supervised DO; may require firmware alignment.
- TRICONEX 3805E — For systems requiring expanded I/O; consult system architecture documentation.
Compatibility depends on Tricon chassis version, system software revision, and project-specific safety requirements. Contact Konmask for pre-sales technical verification.
Why Choose the Original Model
- Proven SIL 3 Safety Performance: The 3624 is TÜV-certified and validated for use in IEC 61508 SIL 3 safety loops — no re-validation required when using the original part.
- Seamless System Integration: Plug-and-play replacement within existing Tricon TMR chassis without configuration changes.
- Supervised Output Integrity: Built-in line fault detection prevents undetected wiring failures, a critical requirement in SIS applications.
- Long Field Track Record: Widely deployed in global SIS installations since the 1990s; extensive field reliability data available.
- Regulatory Compliance: Maintains existing SIL certification and functional safety documentation for your plant.
Typical Applications
- Emergency Shutdown Systems (ESD) in oil & gas upstream and downstream facilities
- Burner Management Systems (BMS) in power plants and refineries
- High Integrity Pressure Protection Systems (HIPPS)
- Compressor and turbine safety shutdown control
- Chemical reactor safety interlocks
- Offshore platform safety systems
- LNG terminal process safety control
System Compatibility
- Compatible Chassis: Triconex Tricon TMR Safety System (Model 3000 series chassis)
- System Software: TriStation 1131 v3.x and above (verify with your project baseline)
- Slot Type: Standard Tricon I/O slot (non-MP slot)
- Power Requirements: Supplied via Tricon backplane; no external power wiring required
- Not Compatible With: Trident, Tri-GP, or Tricon CX platforms without engineering review
Selection Guide
Use the following criteria to confirm the TRICONEX 3624 is the correct module for your application:
- Step 1 — Confirm Platform: Verify your chassis is a Tricon 3000-series TMR system.
- Step 2 — Check I/O Requirements: Confirm you need 32-channel supervised digital outputs at 24 VDC.
- Step 3 — Verify Supervision Needs: If open/short-circuit line fault detection is required, the 3624 is appropriate; unsupervised applications may use lower-cost alternatives.
- Step 4 — Review SIL Target: For SIL 2 or SIL 3 loops, the 3624 is validated; for SIL 1 applications, consider cost-optimized alternatives.
- Step 5 — Check Firmware Baseline: Confirm TriStation software version compatibility with your existing project file.
- Step 6 — Spare Parts Strategy: For long-term plant operations, consider stocking 1–2 spare units per chassis to minimize unplanned downtime.

Replacement & Compatibility FAQ
Q: Can the TRICONEX 3625 directly replace the 3624?
A: In most Tricon 3000-series systems, yes — the 3625 is the recommended upgrade path. However, TriStation project file updates may be required. Consult your system integrator.
Q: Is the 3624 still in production?
A: The TRICONEX 3624 is considered a mature/legacy product. Schneider Electric may supply it as a spare part; availability varies by region. Konmask maintains surplus stock to support ongoing plant operations.
Q: What is the difference between supervised and unsupervised digital outputs?
A: Supervised outputs include continuous line fault detection (open and short circuit monitoring), which is mandatory for SIL-rated safety loops. Unsupervised outputs do not provide this diagnostic capability.
Q: Can I use the 3624 in a Trident system?
A: No. The 3624 is designed exclusively for the Tricon TMR platform. Trident systems use a different I/O module family.
Q: Do you provide a warranty?
A: Yes. Konmask offers a standard 12-month warranty on all modules. Extended warranty and exchange programs are available — contact us for details.
Q: How do I verify authenticity of the module I receive?
A: Each module is shipped with serial number documentation. You may verify the serial number with Schneider Electric’s product authentication service. Konmask provides full traceability records on request.
