TRICONEX 3002 – TMR Controller Module for High‑Integrity Safety Instrumented Systems

The TRICONEX 3002 is a core module used inside the Tricon Triple Modular Redundant (TMR) safety platform. From my experience, engineers choose it when they need deterministic logic execution, robust diagnostics, and continuous operation in demanding SIS applications—think ESD, furnace/BMS, and HIPPS. One thing I appreciate is how it works as part of the triplicated architecture, so a single channel issue typically won’t take the system down.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery time: 1 week for in-stock; no more than one month at the latest
• Payment method: 50% advance payment, full payment for delivery
• Express delivery methods: FedEx, UPS, DHL

Key Features

• TMR architecture with on-line fault tolerance – Three independent channels with voting logic help sustain operation even if one path is impaired.
• Continuous self-diagnostics – Extensive built-in tests and status reporting make it easier to pinpoint issues quickly.
• Hot-swap within the rated system – Typically supports on-line replacement in a properly configured Tricon chassis to minimize downtime.
• Backplane-integrated operation – No direct field wiring on the module; it interacts with I/O and communication modules via the Tricon backplane.
• Engineering tool compatibility – Designed to work with TriStation environments used for logic management and system diagnostics.
• SIS-ready platform – When used as part of a certified Tricon system, it supports SIL 3 safety functions in many process applications.

Technical Specifications

Application Fields

In many cases, the TRICONEX 3002 is selected for mission-critical process safety roles where continuous availability is expected:

• Emergency Shutdown (ESD) systems in oil & gas production and refining
• Burner Management Systems (BMS) for boilers, furnaces, and heaters
• High-Integrity Pressure Protection Systems (HIPPS)
• Process interlocks and critical trip functions in petrochemical units
• Turbomachinery protection and auxiliary safety logic in power generation

Advantages & Value

• Reliability first – TMR voting and extensive diagnostics help maintain process uptime, even during single-channel faults.
• Lifecycle continuity – The Tricon platform has long-term market support, which typically reduces risk for expansion and spares.
• Compatibility – Works within the broader Triconex ecosystem of I/O and communication modules; simplifies brownfield upgrades.
• Cost of ownership – Hot-swap capability and quick fault isolation can lower maintenance overhead in many plants.
• Technical backing – Broad installed base means more field know-how, and faster troubleshooting paths.

A maintenance lead at a Gulf Coast refinery told us they value the way the module’s diagnostics “make failures boring”—you see it, you isolate it, and you keep running while you schedule the swap.

Installation & Maintenance

• Cabinet standards – Mount within a Tricon chassis housed in a clean, well‑ventilated industrial cabinet; maintain adequate clearance for airflow and service.
• Power and grounding – Use the approved Tricon power entry module and follow single‑point grounding practices; keep noise sources segregated.
• Wiring – Field wiring goes to dedicated I/O cards, not to the 3002; route I/O and communication cabling per SIS wiring practices.
• Hot replacement – The platform supports on-line module replacement; follow the site MOC and bypass procedures, confirm channel status, and handle with ESD precautions.
• Routine care – Periodic visual inspection, connector reseat checks, and dust removal with dry, oil‑free air. Align firmware and configuration revisions across the system before any update.

Quality & Certifications

• Designed for use in IEC 61508 SIL 3 safety architectures when deployed within a certified Tricon system
• CE and UL marks are commonly available on Triconex platform hardware
• RoHS-compliant hardware is widely adopted in the platform generation this module belongs to
• Warranty: 365 days (replacement or repair terms per order)

Common Companion Components

• TRICONEX 3008 – Main chassis (slot frame) used to host controller and I/O cards
• TRICONEX 3503E – Main processor module used in many Tricon configurations
• TRICONEX 3625 / 3721 – Example DI/AI modules for field signal interfacing
• TRICONEX communication modules – For external DCS/PLC connectivity and TriStation access

If you’re planning a system expansion or need a functional spare, the TRICONEX 3002 fits smoothly into existing Tricon backplanes. You might notice that lead times for safety hardware fluctuate; we typically recommend confirming slot assignment and firmware compatibility upfront to avoid on‑site surprises.
