TRICONEX 4000093-110N Safety System Module

Product Description

The TRICONEX 4000093-110N is a critical component from the Triconex/Tricon family of Triple Modular Redundant (TMR) safety instrumented systems (SIS), manufactured by Emerson. This specific part number identifies a main processor module, a communication module, or a vital power supply unit for the Tricon controller chassis. As a core system module, the TRICONEX 4000093-110N is responsible for executing safety logic, managing high-speed communication between redundant channels, or providing conditioned power to the TMR system’s critical electronics. Engineered for the highest levels of fault tolerance and reliability, this module is designed to operate continuously in harsh industrial environments where system failure is not an option. For detailed safety manuals, hardware specifications, and configuration guides, please visit the official product resource: TRICONEX 4000093-110N. The integration and flawless operation of the 4000093-110N module are fundamental to the integrity of the entire safety shutdown system, ensuring that safety functions are performed with the required Safety Integrity Level (SIL 3) availability and reliability. Its TMR architecture is central to the system’s ability to detect faults, perform 2-out-of-3 voting, and maintain operation even during a single module failure.

Product Parameters

• Product Model: TRICONEX 4000093-110N
• System Platform: Triconex Tricon TMR Safety Instrumented System.
• Module Type: System-Level Module (e.g., Main Processor, Communication Processor, or System Power Supply – specific function must be verified via Triconex documentation for this exact part number).
• Primary Function:
  • If a Main Processor: Contains three independent, synchronized microprocessors, each executing the same application logic for one leg of the TMR system.
  • If a Communication Module: Manages the high-speed TriBus for inter-processor communication or external network interfaces (e.g., Modbus, TCP/IP).
  • If a Power Supply: Provides redundant, isolated DC power to the three separate chassis legs from an AC or DC source.
• TMR Architecture: Integral part of the TMR design, featuring triple redundancy for all critical functions.
• Diagnostics: Comprehensive continuous online self-diagnostics and fault detection with detailed status reporting.
• Communication: If a processor or comms module, utilizes the proprietary high-speed TriBus or TRISTATION communication ports.
• Safety Certification: Designed and certified for use in Safety Instrumented Systems up to SIL 3 according to IEC 61508 and IEC 61511 standards.
• Hot-Swap Capability: Designed to be hot-swappable in a redundant configuration, allowing replacement without shutting down the safety system.

Advantages and Features

• Ultra-High Fault Tolerance: The TMR architecture ensures no single point of failure. The system can suffer a fault in one of the three channels (including a fault in the 4000093-110N module’s leg) and still maintain the safety function without a spurious trip.
• Continuous Diagnostics: Performs rigorous, ongoing diagnostics to detect failures within milliseconds, ensuring the system’s health is constantly verified and dangerous undetected faults are minimized.
• High Availability and Safety: Simultaneously achieves high safety availability (to prevent accidents) and high operational availability (to avoid nuisance shutdowns), which is the hallmark of a TMR system.
• Secure and Deterministic Performance: Provides predictable, millisecond-level response times for safety functions and is designed with cybersecurity features to protect against malicious interference.
• Proven Safety Heritage: As a module within the industry-leading Triconex platform, it benefits from decades of proven application in the world’s most critical safety systems in oil & gas, petrochemical, and power generation.

Application Cases in Various Fields

• Offshore Oil & Gas Platform (ESD): Serves as the main processing or communication module in the Tricon controller that executes the Emergency Shutdown (ESD) logic, processing signals from gas detectors and pressure transmitters to safely isolate sections of the platform.
• Refinery Furnace Protection (BMS): Acts as a critical component in the Burner Management System (BMS) controller, ensuring safe start-up, operation, and shutdown of large process heaters to prevent furnace explosions.
• Gas Turbine Overspeed Protection: Used in the safety controller dedicated to turbine protection, ensuring that overspeed trips are executed with extreme reliability to prevent catastrophic mechanical failure.
• Chemical Plant High Integrity Pressure Protection System (HIPPS): Forms part of the logic solver that activates emergency valves to isolate overpressure scenarios in reactor systems.

Comparison with Competing Products

The TRICONEX 4000093-110N competes with safety system modules from other vendors like HIMA and Siemens (SIMATIC Safety). Its primary differentiator is its dedicated hardware-based TMR architecture. Unlike 1oo2D (one-out-of-two with diagnostics) systems that use dual redundancy with software diagnostics, the Tricon system’s TMR design, enabled by modules like the 4000093-110N, provides inherent hardware fault tolerance and simpler, more deterministic fault detection. This makes it the preferred choice for applications where the highest possible safety availability and protection against common-cause failures are required.

Selection Suggestions and Precautions

1. Function Identification is Critical: It is imperative to identify the exact function of the TRICONEX 4000093-110N module (Processor, Comms, Power) by cross-referencing the part number with the Tricon system’s configuration drawings, Bill of Materials (BOM), or Emerson technical support. Using the wrong module type will cause system failure.
2. Tricon System Compatibility: The module must be compatible with the specific Tricon chassis model (e.g., Tricon v9, v10, Tricon CX) and the system’s firmware version. Mixing incompatible hardware revisions can compromise system integrity.
3. Safety Lifecycle Compliance: This module is part of a Safety Instrumented System (SIS). Its selection and replacement must be governed by the plant’s Safety Lifecycle management procedures, including a Management of Change (MOC) process and updates to the Safety Requirements Specification (SRS).
4. Handling and ESD Protection: Treat the module as sensitive safety-critical electronics. Use proper electrostatic discharge (ESD) protection during all handling and installation procedures.
