Product Introduction
The TRICONEX 3000590-110 is an External Termination Assembly (ETA) used with the Tricon safety system. It is associated with termination-panel model 9668-110 and cable 4000094-110. The official-style Tricon technical documentation identifies this exact part-number relationship, making the termination-assembly classification considerably more reliable than generic reseller descriptions.
The TRICONEX 3000590-110 is not a Tricon main processor or I/O module. Its role is at the field-interface level: it provides the physical termination point for field wiring and connects that wiring to the corresponding Tricon I/O through the specified interface cable.
For Tricon v9–v11 systems, the installation documentation specifically lists 9668-110FC with cable 4000188-110 for use with the 3636TC configuration. The documentation also identifies the associated ETA as 3000590-110C when the LSZH cable option is required.
This distinction matters when sourcing replacements because 3000590-110, 3000590-110C, 9668-110, and the associated cable numbers are related but are not necessarily interchangeable ordering references.

Main Features & Field Considerations
External field termination
The 3000590-110 provides the interface between field wiring and the Tricon I/O system. It is therefore part of the signal path even though it does not perform the actual control logic.
Documented part-number relationship
The Tricon technical guide provides a clear cross-reference:
9668-110 → 3000590-110 → 4000094-110.
System-specific compatibility
Do not select this termination assembly solely by connector appearance. Confirm:
- Tricon system version
- I/O module model
- Termination-panel model
- Interface cable
- Field signal type
- Wiring arrangement
- Cabinet drawings
Cable matching
The standard technical-product cross-reference associates 3000590-110 with 4000094-110. A different Tricon termination cable should not be substituted simply because its connector appears physically compatible.
Replacement Checks
Before replacing a TRICONEX 3000590-110, verify:
- 3000590-110 marking
- 9668-110 termination-panel identification
- Associated Tricon I/O module
- Interface cable number
- Field terminal assignments
- System version
- Wiring polarity and signal type
- Physical terminal condition
- Grounding/shielding arrangement
- Whether the installation requires the 3000590-110C variant
For a safety-system installation, field wiring should be isolated according to the site’s approved maintenance procedure before removing the termination assembly.
Typical Applications
The TRICONEX 3000590-110 is used in Tricon safety-system installations for:
- Safety Instrumented Systems (SIS)
- Emergency shutdown systems
- Process shutdown applications
- Oil and gas facilities
- Refining and petrochemical plants
- Chemical processing
- Power-generation safety systems
- Tricon field I/O termination
Procurement Note
For TRICONEX 3000590-110, the strongest identification is:
3000590-110 / 9668-110 / 4000094-110
The Tricon Technical Product Guide explicitly establishes this cross-reference.
One important procurement detail: the newer Tricon v9–v11 planning documentation references 9668-110FC with cable 4000188-110, and identifies 3000590-110C as an LSZH-compatible ETA option. Therefore, do not assume that every 9668-110 installation uses the same cable or ETA suffix. Match the exact system revision and cable configuration before ordering.
