- Electrical Rating: Not reliably established from available public references; verify against the equipment documentation
- Replacement Role: Maintenance spare for existing Tricon installations
Important procurement note: Public descriptions for 4000094-313 are inconsistent. Some references call it a cable assembly, while others incorrectly categorize the same part number as a module or supply/interface component. The stronger evidence identifies it as a cable assembly.
For a safety-system purchase, I would require a photograph of the actual part before approving a substitution.
Application Scenarios & Pain Points
When a Tricon cabinet develops intermittent I/O faults, engineers often check processors and I/O cards first. A degraded cable connection can sit unnoticed for much longer, particularly when vibration or repeated cabinet maintenance has stressed the connector.

Typical Applications
- Tricon SIS Cabinets: Used as an interconnection cable within legacy Tricon safety-system installations.
- I/O Interface Maintenance: Appropriate when troubleshooting points toward the cable path rather than the Tricon processor or I/O module itself.
- Shutdown Spare Inventory: Keeping the exact cable assembly on hand can prevent a minor wiring problem from extending a planned outage.
- Legacy System Support: Particularly useful where the original Tricon cabinet configuration must remain intact and an exact replacement is preferred over field fabrication.
Field Case:
A maintenance crew chasing intermittent I/O diagnostics may find that the controller and I/O modules test normally, while continuity changes when the cable is moved at the connector. In that situation, replacing the exact cable assembly is usually a cleaner repair than cutting and reterminating an undocumented field cable.
Related Products
- TRICONEX 4000094-310 — Another Tricon cable assembly reference. It is associated with the same general cable/connection family, but it should not be considered interchangeable with 4000094-313 without checking the cabinet drawings and connector arrangement.
- TRICONEX 4000093-306 — Related legacy Tricon cable/interface assembly. Its part-number family is similar, but the termination and intended connection point can differ.
- TRICONEX 4000093-316 — Another legacy Tricon cable/interface-related part. It should be treated as a separate assembly rather than a substitute for 4000094-313.
- TRICONEX 4000103-513 — Related Tricon interface cable assembly used for other system connections. Connector and application differences make exact part-number matching necessary.
- TRICONEX 4000066-025 — Tricon I/O communication bus cable reference. This serves a different communication function and is not a direct replacement for 4000094-313.
- TRICONEX 4000056-025 — Another I/O communication bus cable used in Tricon architectures. Application and connector configuration must be checked before selection.
- TRICONEX 4000093-110N — Main Processor Module. This is a controller component rather than a cable, but it is part of the same legacy Tricon system architecture and may be involved when diagnosing communication faults.
- TRICONEX 1600071-001 — Tricon interface module associated with legacy system hardware. It performs an active electronic interface function and should not be confused with the passive cable assembly.
