TRICONEX 8312 Power Module | Replacement, Equivalent & Selection Guide
The TRICONEX 8312 is a dedicated power supply module for the Triconex Tricon Safety System — a Triple Modular Redundant (TMR) safety controller widely deployed in oil & gas, petrochemical, and power generation facilities. It provides regulated DC power to the Tricon chassis backplane, ensuring uninterrupted operation of all installed I/O and communication modules.
Whether you are sourcing a direct replacement for a failed unit, evaluating a functionally equivalent spare, or comparing cross-brand substitutes during a system upgrade, this guide is designed to support your selection decision with accurate technical data and sourcing transparency.

Compatible Replacement & Equivalent Models
1. Direct Drop-in Replacements
The following part numbers are direct replacements for the 8312 and can be installed without any configuration change:
- TRICONEX 8312A — Revised hardware revision of the 8312; functionally identical, same slot footprint. Verify firmware compatibility with your Tricon MP (Main Processor) revision before installation.
- TRICONEX 8312B — Later production revision; backward-compatible in most Tricon v9.x and v10.x systems. Confirm with your system integrator.
2. Functional Equivalents
These modules perform the same power supply function within the Tricon platform but may require chassis or firmware verification:
- TRICONEX 8310 — Earlier generation power module; compatible with older Tricon chassis. Lower output capacity; confirm total chassis load before substituting.
- TRICONEX 8311 — Mid-generation variant; check chassis backplane connector pinout before use as a substitute.
Prerequisite: Functional equivalents must be validated against your specific chassis revision and Tricon software version. Consult the Tricon Hardware Planning Guide (document 9600-1-MS-0001).
3. Cross-Brand Alternatives
For system migrations or lifecycle replacements where a full platform evaluation is underway:
- Rockwell Automation / Allen-Bradley 1756-PA75 — ControlLogix power supply; not a drop-in substitute, but a reference point for cross-brand TMR power supply benchmarking during platform migration projects.
- Honeywell Safety Manager SC Power Module — Applicable only in full system replacement scenarios; requires complete re-engineering of I/O and logic.
⚠ Cross-brand alternatives are NOT plug-and-play substitutes. They are listed for reference in system migration planning only. Contact Konmask for migration feasibility assessment.
Why Choose the Original TRICONEX 8312
- Precision-Engineered for TMR Architecture: The 8312 is designed specifically for Tricon’s Triple Modular Redundant topology — voltage rails, timing, and fault diagnostics are tuned to the Tricon backplane protocol.
- SIL 3 Certified: Carries IEC 61508 SIL 3 certification, mandatory for safety instrumented systems (SIS) in high-hazard process industries. Third-party substitutes rarely carry equivalent certification for this chassis.
- Hot-Swap Redundancy: Supports live replacement without system shutdown, critical for continuous-process facilities where downtime costs are measured in tens of thousands per hour.
- Full OEM Compatibility: Guaranteed compatibility with all Tricon MP revisions, I/O modules, and Tristation 1131 programming environment — no integration risk.
- Traceable Warranty & Support: Sourced through verified channels, each unit supplied by Konmask includes documentation supporting OEM warranty claims and Schneider Electric technical support eligibility.
- Long-Term Availability: Konmask maintains strategic stock of legacy Triconex modules to support installed base through end-of-life cycles, reducing obsolescence risk.
Typical Applications
- Oil & Gas — Upstream: Emergency Shutdown Systems (ESD) on wellhead control panels and production separators requiring SIL 3 power integrity.
- LNG & Petrochemical Plants: Burner Management Systems (BMS) and High Integrity Pressure Protection Systems (HIPPS) where power module failure must be detected and isolated within milliseconds.
- Refinery Process Control: Redundant power supply for Tricon controllers managing distillation column safety interlocks.
- Power Generation: Turbine overspeed protection and boiler safety systems using Tricon TMR architecture.
- Nuclear Auxiliary Systems: Non-safety-class auxiliary control systems in nuclear facilities where TMR redundancy is specified.
- Offshore Platforms: Fire & Gas (F&G) detection system controllers in marine environments requiring wide-temperature, vibration-tolerant power modules.
System Compatibility
The TRICONEX 8312 is designed for use within the following Tricon system components:
- 8110 / 8111 / 8112 — Tricon Main Chassis (standard and extended configurations)
- 8100 / 8101 — Tricon Main Processor (MP) modules
- 3700A / 3703E / 3805E — Digital Input/Output modules (chassis-powered)
- 3721 / 3805H — Analog Input modules requiring stable ±12 VDC rail
- 4351B / 4352B — Tricon Communication modules (EICM, TCM)
- Tristation 1131 v4.x / v9.x / v10.x — Programming and diagnostic software environment
Selection Guide
Answer these three questions before confirming your order — or contact Konmask and we will guide you through the process:
- What is your Tricon chassis model and revision? The 8312 is compatible with 8110/8111/8112 series chassis. If you have an older 7xxx-series chassis, a different power module may be required. Share your chassis label with us for confirmation.
- Are you replacing a failed unit or building a spare inventory? For emergency replacements, Konmask offers same-day dispatch on in-stock units with full test documentation. For spare inventory, we can provide quantity pricing and staggered delivery.
- Do you require a specific hardware revision (8312, 8312A, 8312B)? If your system integrator or OEM has specified a revision, confirm this before ordering. If unsure, share your current installed revision and we will advise on the safest equivalent.

Replacement & Compatibility FAQ
Q1: Can the TRICONEX 8312A directly replace the 8312 without any system changes?
In most cases, yes. The 8312A is a hardware revision of the 8312 with the same electrical specifications and chassis footprint. However, you should verify that your Tricon Main Processor firmware version supports the 8312A revision. Konmask can advise based on your system’s current MP revision.
Q2: Is the TRICONEX 8312 compatible with both 120 VAC and 240 VAC input power?
Yes. The 8312 features auto-ranging AC input (120/240 VAC, 50/60 Hz), making it a suitable equivalent for installations in both North American and international facilities without hardware modification.
Q3: What is the best substitute for the TRICONEX 8312 if the original is no longer available?
The closest functional equivalent within the Tricon platform is the 8312A or 8312B revision. If these are also unavailable, the 8311 may serve as a substitute in older chassis configurations, subject to load capacity verification. Konmask maintains stock of all three variants and can recommend the safest substitute based on your specific system configuration. Cross-brand substitutes are not recommended for SIL 3 applications without full re-validation.
