Description
Key Technical Specifications
- Manufacturer: TRICONEX / Invensys
- Part Number: 4000103-513
- Product Type: External Terminal AI Cable Assembly
- System Family: Tricon Safety Instrumented System
- Signal Application: Analog Input (AI)
- Primary Function: Interconnection between Tricon AI hardware and external termination circuitry
- Installation Location: Tricon I/O cabinet / termination interface
- Cable Configuration: System-specific prefabricated assembly
- Connector Configuration: Must be matched to the installed system
- Cable Length: Verify against the original assembly
- Firmware: None expected in the passive cable assembly itself
- Replacement Role: Tricon I/O maintenance spare
The part-specific references identify 4000103-513 as an external terminal AI cable assembly. A separate reference associates it with the CN1753100199-01/4000103-513 cable designation.
Procurement caution: A few catalogs incorrectly classify 4000103-513 as a communication module or redundant power supply. Those descriptions conflict with the more specific cable-assembly references. For an actual replacement, the physical cable and connector configuration should take precedence over a generic catalog title.
Application Scenarios & Pain Points
Analog input problems are particularly unpleasant during plant troubleshooting. A transmitter may be blamed, then the AI module, then the termination board—while the actual problem sits in the cable between them.

Typical Applications
- Tricon Analog Input Cabinets: Provides the prefabricated connection between the AI-side hardware and external termination circuitry.
- Process Measurement Systems: Suitable for Tricon installations handling analog process variables such as pressure, temperature, flow, and level.
- Legacy SIS Maintenance: Useful where the original Tricon cabinet architecture must remain unchanged and field-fabricating a replacement cable would introduce unnecessary uncertainty.
- Shutdown Spare Inventory: A worthwhile spare when an installed system already uses the exact 4000103-513 assembly.
Field Case:
A maintenance team investigating unstable analog values may see the transmitter and AI card testing normally while the signal changes when the cabinet cable is moved. In that situation, checking continuity and connector integrity across the 4000103-513 assembly can isolate the fault without unnecessarily replacing the AI module.
Related Products
- TRICONEX 4000093-306 — Output cable assembly used on the output side of the Tricon I/O architecture. It is functionally different from the AI-oriented 4000103-513 and should not be substituted.
- TRICONEX 4000094-313 — Related Tricon interface cable assembly. Similar legacy hardware category, but the termination and signal application differ; verify the cabinet drawing before substitution.
- TRICONEX 4000093-316 — Another legacy Tricon interface/power-related assembly. Similar numerical family does not establish interchangeability.
- TRICONEX 4000098-513 — Analog-output prefabricated cable reference. It is particularly relevant as a comparison because 4000103-513 is associated with AI, while 4000098-513 is associated with analog output.
- TRICONEX 3700A — Analog input module family used for Tricon AI applications. Unlike 4000103-513, this is active I/O electronics that performs signal processing.
- TRICONEX 3706A — Thermocouple analog-input module. It handles thermocouple signals and therefore represents a specific AI hardware application rather than a general cable replacement.
- TRICONEX 9761-210 — Analog input termination board/interface hardware. This is a complementary termination-side component and should be checked alongside the cable when troubleshooting AI signal paths.
- TRICONEX 4000066-025 — I/O communication bus cable. It serves system communication rather than analog signal termination, so it is not an alternative to 4000103-513.
