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.
