Safety Relay Output Solution – TRICONEX 3636T | Tricon TMR Series
Where This Product Is Used
The TRICONEX 3636T Relay Output Module is a critical safety-rated output component deployed in Triple Modular Redundant (TMR) control architectures across high-hazard industries. Engineers specify this module wherever a certified, fault-tolerant relay output interface is required between the safety PLC and field actuators.
Typical deployment environments include:
- Oil & Gas Production & Refining — Emergency Shutdown Systems (ESD), High Integrity Pressure Protection Systems (HIPPS), and compressor/turbine trip circuits
- Petrochemical & Chemical Plants — Burner Management Systems (BMS), reactor interlock loops, and toxic gas release prevention systems
- LNG Terminals & Pipelines — Valve actuator control, fire & gas detection output, and pipeline isolation logic
- Power Generation — Turbine protection, boiler safety shutdown, and generator trip relay interfaces
- Offshore Platforms — Wellhead control panels, subsea control system interfaces, and platform ESD
- Nuclear & Utilities — Safety instrumented function (SIF) output loops requiring IEC 61511 compliance

Why Engineers Specify This Model
- SIL 3 Rated Architecture — The 3636T operates within the Tricon TMR framework, achieving SIL 3 capability through hardware fault tolerance (HFT=2) and 2oo3 voting logic, meeting the most stringent functional safety requirements.
- Hot-Swap / Online Replacement — Modules can be replaced under power without process shutdown, minimizing plant downtime during maintenance windows.
- Proven Field Reliability — TRICONEX TMR systems have accumulated decades of runtime in critical process industries; the 3636T is a well-documented, widely deployed output module with extensive installed base.
- Relay Contact Versatility — Dry contact relay outputs interface directly with solenoid valves, motor starters, and alarm annunciators without additional signal conditioning.
- Diagnostic Coverage — Continuous self-diagnostics detect channel faults and report to the Tricon main processor, supporting proof-test interval optimization.
- Backward Compatibility — Compatible with existing Tricon chassis and I/O termination assemblies, enabling like-for-like replacement without rewiring.

Application-Specific FAQ
Q: Is the 3636T compatible with the Tricon v9 and v10 chassis?
A: The 3636T is designed for the Tricon TMR platform. Compatibility depends on chassis generation and backplane revision. Please provide your chassis model number when inquiring so we can confirm fit.
Q: Can this module be used in a SIL 2 application?
A: Yes. A SIL 3-rated module can be deployed in SIL 2 applications. The SIL level of the Safety Instrumented Function is determined by the overall loop design, not the module rating alone.
Q: Do you provide a warranty on used/surplus modules?
A: We offer a 90-day functional warranty on all tested units. Warranty terms are provided with the quotation.
Q: What is the typical lead time?
A: In-stock units ship within 1–3 business days. For out-of-stock items, lead time is quoted based on current sourcing pipeline, typically 2–6 weeks.
Q: Can you supply the matching termination assembly (3703E)?
A: Yes. We stock a range of Tricon termination assemblies and I/O accessories. Include your full BOM in your RFQ for consolidated sourcing.
Q: Do you export internationally?
A: Yes. We ship globally via DHL Express and FedEx International Priority. Export documentation, including commercial invoice and HS code declaration, is provided for all international shipments.
