TRICONEX 3564 – TMR Discrete Output I/O Module for Tricon Safety Systems

The TRICONEX 3564 is commonly specified anywhere high-integrity shutdown or permissive logic is required. Typical use cases include:

• Oil & Gas: ESD valve actuation, F&G outputs, HIPPS valve control, compressor/turbine trip logic.

• Petrochemical & Chemical: Reactor emergency quench, burner management outputs, inerting/purging sequences.

• Power Generation: Turbomachinery protection, boiler/trip relays, auxiliary system permissives.

• Pharma & Specialty Process: High-integrity interlocks and controlled shutdown pathways.

• Pipelines & Terminals: Pump shutdown, pressure protection output chains, loading arm interlocks.

• Proven reliability: The TMR architecture and diagnostic coverage typically reduce spurious trips and help maintain availability.

• Lifecycle continuity: Ideal as a drop-in spare for existing Tricon installations, preserving your validated logic and wiring practices.

• Maintenance efficiency: Online replacement and clear LEDs shorten mean-time-to-repair; teams often report faster turnaround during planned outages.

• System compatibility: Works within the broader Triconex ecosystem (TriStation engineering, TCM communications, certified termination hardware).

• Safety compliance: Supports SIL3-rated functions when used in a certified Tricon system, which in many cases simplifies audits and functional safety reviews.

A maintenance lead from a Middle East refinery told us they swapped a 3564 during a hot repair in under 10 minutes, and the diagnostics made it obvious which channel group had faulted. That seems to be the norm with properly maintained Tricon racks.

• Cabinet and environment: Install in a clean, ventilated enclosure; maintain ambient within the Tricon system’s specified range (typically up to 60°C). Allow space for airflow around the chassis.

• Wiring: Use the designated termination assembly and cable set for the 3564. Keep field cable shields and grounding consistent with site standards to minimize noise and nuisance trips.

• Safety: De-energize affected circuits before changing field wiring. Follow ESD handling procedures when inserting/removing modules.

• Commissioning: Verify channel mapping in TriStation 1131, confirm output action (energize-to-trip vs. de-energize-to-trip), and proof-test per safety plan.

• Routine upkeep: Perform periodic visual inspections, check terminal tightness on the termination panel, review diagnostics/sequence-of-events logs, and align firmware with validated system revisions when applicable.

• TRICONEX 3008 Main Processor – controller CPU running your safety logic with TMR voting.

• TRICONEX 3700A Tricon Communication Module (TCM) – system communications and TriStation access.

• TRICONEX Power Modules (e.g., 8110/8111) – redundant power feeding the chassis backplane.

• Matched Termination Assemblies for 3564 – field wiring interface; select types to suit output voltage/current and isolation needs.

• TriStation 1131 engineering software – configuration, diagnostics, and forcing for commissioning and maintenance.

• IEC 61508 SIL3 (system-level certification when used in a certified Tricon configuration)

• CE compliance and UL recognition are commonly available for Triconex modules (verify per system BOM and region).

• RoHS status may vary by hardware revision; many sites accept Triconex modules under industrial exemptions—check site policy.

• Manufacturer’s warranty is typically 12 months for new units; terms can vary by procurement channel.

Note: Specific electrical ratings (voltage/current per channel and channel count) can vary by termination assembly and hardware revision. If you share your field device type and trip philosophy, we can match the exact 3564 variant and TA combination that fits your loop calculations.
