Description
Key Technical Specifications
- Manufacturer: TRICONEX / Invensys
- Part Number: 4000093-306
- Product Type: Output Cable Assembly
- System Family: Tricon Safety Instrumented System
- Primary Function: Output-side I/O interconnection
- Application: Tricon I/O base/interface and external termination arrangement
- Hardware Category: Legacy Triconex system accessory
- Signal Direction: Output
- Connector Configuration: Must be verified against the installed assembly
- Cable Length: Verify from the original assembly or cabinet drawing
- Electrical Rating: Not reliably established from authoritative public documentation
- Replacement Role: Direct part-number spare for an existing 4000093-306 installation
The available installation documentation describes Tricon I/O bases and interconnection assemblies as part of the I/O column installation architecture.
Application Scenarios & Pain Points
When a safety-system output starts behaving intermittently, replacing the electronic I/O module is not automatically the right answer. A cable assembly with one marginal contact can create a surprisingly convincing “bad module” symptom.

Typical Applications
- Tricon I/O Cabinets: Used to carry output connections between the Tricon I/O hardware and its associated termination/interface arrangement.
- Legacy SIS Maintenance: Particularly relevant when a plant has older Tricon cabinets that still depend on the original cable architecture.
- Shutdown Spare Inventory: A relatively small cable can become a major outage problem when the exact connector and pin arrangement are no longer readily available.
- Output Troubleshooting: Useful when module diagnostics are normal but field output behavior remains intermittent.
Field Case:
A maintenance team troubleshooting an intermittent shutdown signal may initially suspect the digital output module. After checking the I/O diagnostics and field wiring, movement of the interconnection cable can reveal a marginal connector contact. Replacing the correct cable assembly can resolve the fault without disturbing the processor or I/O configuration.
Related Products
- TRICONEX 4000094-313 — Related Tricon interface/supply cable assembly. Similar legacy hardware, but it should not be substituted for 4000093-306 without checking the connector and cabinet drawing.
- TRICONEX 4000103-513 — Another Tricon cable/interface assembly reference. Public references identify it with external termination/AI applications, making it functionally different from the output-oriented 4000093-306.
- TRICONEX 4000093-316 — Related legacy Tricon cable/interface component. Similar numbering does not establish interchangeability.
- TRICONEX 1600071-001 — Triconex interface/control hardware used in legacy Tricon systems. Unlike 4000093-306, this is an electronic interface assembly rather than simply an output cable.
- TRICONEX 3503E — Tricon digital input module. It belongs to the I/O family but handles input signals rather than the output-side connection associated with 4000093-306.
- TRICONEX 3664 — Tricon analog output module. It performs active analog output processing, whereas 4000093-306 serves as the interconnection hardware.
- TRICONEX 3611E — Tricon digital output module. This is an active I/O module and therefore a functional component upstream of the output cable assembly.
- TRICONEX 3805H — Tricon analog output module. Applicable to analog output applications rather than the cable assembly itself.
