Triconex TCM4355X Tricon Communication Module (TCM) | Replacement, Equivalent & Selection Guide
The Triconex TCM4355X is a Tricon Communication Module (TCM) designed for use in Triconex Triple Modular Redundant (TMR) safety systems. It provides high-speed, deterministic communication between the Tricon main chassis and remote I/O panels or host supervisory systems, making it a critical component in process safety and control architectures across oil & gas, petrochemical, and power generation industries.
At Konmask.com, we specialize in sourcing, cross-referencing, and supplying both original and compatible replacement modules for Triconex safety systems. This page provides a comprehensive selection guide to help engineers and procurement teams make informed decisions.

System Compatibility
The TCM4355X is designed for use within the Triconex Tricon TMR platform. Confirm the following before ordering:
- Chassis Model: Compatible with standard Tricon main chassis (verify slot type and backplane revision)
- Firmware Version: TCM firmware must match the Tricon MP (Main Processor) firmware version
- TriStation Software: Compatible with TriStation 1131 programming environment
- Communication Protocol: Supports Triconex proprietary protocol; confirm host SCADA/DCS interface requirements
- Power Budget: Verify chassis power supply capacity when adding or replacing TCM modules
Selection Guide
Use this guide to determine whether the TCM4355X or an alternative is the right choice for your application:
| Scenario | Recommended Action |
|---|---|
| Direct like-for-like replacement in existing Tricon system | Order TCM4355X (original) — no re-validation needed |
| System is being upgraded to newer Tricon firmware | Evaluate TCM4356X or TCMX with Konmask technical support |
| Budget-constrained MRO replacement with same functionality | Request refurbished / tested TCM4355X from Konmask |
| Expanding Tricon system with additional remote I/O | Confirm chassis slot availability; order matching TCM revision |
| Migrating from legacy Tricon to Trident or Triconex v2 | Contact Konmask for full migration BOM and engineering support |
