Description
Key Technical Specifications
- Manufacturer: TRICONEX / Invensys / Schneider Electric
- Part Number: 4000093-316
- System Family: Tricon Safety Instrumented System
- Hardware Generation: Legacy Triconex equipment
- Reported Function: Power/interface/communication-related assembly
- Application: Tricon system chassis and associated control hardware
- Exact Electrical Rating: Not sufficiently verified from authoritative public documentation
- Connector Configuration: Revision-dependent; verify against the installed unit
- Replacement Status: Legacy/discontinued-type spare component
- Safety System Context: Tricon fault-tolerant safety-control architecture
The distinction is important. Standard Tricon v9–v11 chassis documentation identifies dedicated power modules such as Models 8310, 8311, and 8312, while 4000093-316 appears in other references as a separate legacy part number.
Application Scenarios & Pain Points
A safety-system spare that is merely “electrically similar” is not good enough. During a shutdown, discovering that the connector or assembly revision is wrong can turn a 30-minute replacement into a cabinet-level troubleshooting exercise.

4000093-316
Typical Applications
- Tricon Safety System Maintenance: Kept as a replacement component for existing Triconex installations where the original hardware remains in service.
- Legacy SIS Support: Useful for plants maintaining older safety-instrumented infrastructure rather than replacing an entire controller architecture.
- Shutdown Planning: A practical candidate for critical-spares inventories when the installed cabinet contains this exact part number.
- Troubleshooting and Repair: Particularly relevant when the maintenance team has already identified 4000093-316 from the failed assembly’s nameplate.
Field Note:
For this part, I would photograph the failed assembly before ordering. The reason is simple: public references classify 4000093-316 inconsistently. One source calls it a power supply module, another calls it a communication module, and another groups it with interface cable assemblies. That is a strong signal to verify the physical hardware rather than relying on a catalog title.
Related Products
- TRICONEX 4000093-306 — Closely related legacy Triconex part number. Public references describe it as a power/interface-related assembly; it should not be substituted for 4000093-316 without checking the chassis documentation.
- TRICONEX 4000094-313 — Another related legacy interface/supply assembly. Similar numbering does not establish electrical or mechanical interchangeability.
- TRICONEX 4000103-513 — Related Triconex hardware commonly listed in the same spare-parts family. Its function differs from 4000093-316, so treat it as a complementary/alternative system component rather than a direct replacement.
- TRICONEX 4000093-110N — Main Processor Module reference for Tricon systems. This is controller-processing hardware, not a substitute for 4000093-316.
- TRICONEX 8110 — High-density main chassis. It provides the physical Tricon chassis platform and therefore represents a system-level component rather than a direct replacement.
- TRICONEX 8111 — Related high-density chassis hardware used in Tricon installations. Selection depends on the installed system architecture.
- TRICONEX 8310 — Tricon 120 VAC/DC power module. This is a documented Tricon power-module model and should not be confused with the less clearly documented 4000093-316 assembly.
- TRICONEX 8311 — 24 VDC Tricon power module. In applications requiring ATEX compliance with 230 VAC input, the Tricon planning documentation specifies the 8311 configuration with an appropriate external 24 VDC supply.
- TRICONEX 8312 — 230 VAC power module for Tricon systems. The documentation specifically warns against using the 8312 in ATEX-required hazardous-location applications.
