TRICONEX 3003 – Main Processor Module for Tricon TMR Safety Systems

Plants typically deploy the TRICONEX 3003 where high availability and verifiable safety performance are required. Common roles include:

• Emergency Shutdown (ESD) and High Integrity Pressure Protection (HIPPS)

• Fire & Gas (F&G) detection and mitigation logic

• Burner Management Systems (BMS) in refining and utilities

• Turbine and compressor protection in power and midstream

• Pipeline block valve control and subsea topside safety interlocks

“We swapped a single 3003 during a turnaround and kept the rest of the segment live,” a maintenance lead at a Gulf gas plant told us. “Diagnostics were clear, and proof testing went smoother than usual.”

• Reliability – True 2oo3 voting with continuous diagnostics; tolerant to single faults with graceful degradation.

• Lifecycle assurance – Strong global installed base and multi-year support; spare-part strategies are straightforward in many cases.

• Compatibility – Works within Tricon chassis alongside existing I/O and comms modules; typically minimal disruption in mixed-revision systems when engineered correctly.

• Cost control – Online repair and hot replacement reduce outage requirements and labor overhead during maintenance.

• Traceability – Event logging and well-established TriStation workflows help with audits and MOC processes.

• Cabinet & environment – Install in a standard Tricon chassis within a ventilated control cabinet. Maintain clearance for airflow; avoid excessive vibration and corrosive atmospheres.

• Slotting – The 3003 is used as a set of three processors in adjacent slots. Keep the set matched per the project’s BOM and follow the system slot map.

• Wiring – Field wiring terminates on I/O modules, not on the 3003. Use shielded cables for comms modules and maintain proper grounding.

• ESD handling – Treat the module as ESD-sensitive; use wrist straps and antistatic packaging during replacement.

• Firmware & configuration – Align firmware revisions across the TMR set; validate application downloads with TriStation 1131 and keep a signed backup.

• Routine tasks – Review diagnostics and event logs, verify time sync, perform proof tests per SRS, and keep the cabinet dust-free.

• Designed for use in TüV-certified, IEC 61508 SIL3 Tricon systems when applied per the safety manual

• CE marking and UL/cUL compliance are typical for the product family; specific marks may vary by hardware revision

• RoHS status can depend on vintage; many installations rely on established industrial exemptions—confirm against your site standards

• Manufacturer’s limited warranty is commonly 12 months; extended coverage available through service agreements

When specifying or replacing a TRICONEX 3003, teams typically review the surrounding bill of materials to ensure smooth integration:

• Tricon chassis and power supplies (matching your installed base and redundancy scheme)

• Tricon I/O modules (DI/DO/AI/AO) for process interfacing, kept in matched TMR sets

• Communications modules for programming and integration (e.g., Ethernet/serial gateways within the Tricon family)

• TriStation 1131 software with project backups and validated firmware packages

If you’re planning a like-for-like replacement or a staged modernization, we can help verify part revisions, firmware alignment, and on-site commissioning steps so the changeover is predictable and audit-ready.
