Overview Manuals Specifications Monitoring & Control Safety & Compliance Applications

Features:

  • Triple Modular Redundancy (TMR) Architecture
  • Online Repair & Hot Swapping
  • Extended Remote I/O Capability
The TRICONEX 4310 integrates three independent microprocessor channels on a single module. This design ensures that no single point of failure can compromise your safety system, as the module continuously votes inputs and outputs to guarantee correct execution.

Minimize costly production downtime with the TRICONEX 4310's online repair capability. You can remove and replace the module while the Tricon system remains fully operational, without interrupting field wiring or the control process.

Deploy your safety system across vast facilities efficiently. The TRICONEX 4310 supports remote I/O modules located up to 12 kilometers away, allowing centralised control for geographically dispersed equipment.

The 4310 Invensys Triconex Enhanced Main Processor Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

General

  • Manufacturer Invensys
  • Model 4310
  • Condition New Original ready stock
  • Product Family 3624,8311,8312
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Centralised Logic Execution: The TRICONEX 4310 performs high-speed scanning of user-defined control programs, ensuring deterministic response times for critical safety functions.
  • Integrated Communication Management: It acts as the gateway, managing data exchange between the Tricon chassis, operator workstations, and plant-wide DCS systems via Modbus or TCP/IP.
  • Real-Time Health Monitoring: The module continuously monitors the status of its three internal microprocessors and reports any diagnostic alerts, allowing operators to see the "health" of the processor instantly.
  • Remote I/O Supervision: It monitors and controls I/O modules located kilometers away, providing real-time status updates and ensuring data integrity for distant field devices.
  • Triple Modular Redundancy (TMR): By running three isolated processors simultaneously and voting on the output, the TRICONEX 4310 ensures that no single component failure can cause a loss of safety function.
  • IEC 61508 SIL 3 Certified: The TRICONEX 4310 meets the highest requirements for hardware safety integrity, making it suitable for applications with the most severe risk reduction needs.
  • Online Repair Capability: Designed for fail-safe operations, the TRICONEX 4310 allows faulty modules to be replaced without interrupting the control process, maintaining safety coverage even during maintenance.
  • Harsh Environment Tolerance: The module is built to withstand extreme industrial conditions (temperature, vibration, humidity). Its robust design allows for direct on-site installation near the process, reducing the need for climate-controlled enclosures.
  • Emergency Shutdown (ESD) Systems: The TRICONEX 4310 executes safety logic to safely shut down processes when dangerous conditions are detected, protecting personnel and equipment.
  • Fire & Gas (F&G) Systems: It processes inputs from flame and gas detectors, triggering alarms and mitigating actions like ventilation or deluge systems to prevent explosions or toxic releases.
  • Turbine & Compressor Control: The high-speed processing of the TRICONEX 4310 provides precise control and overspeed protection for critical rotating machinery in power generation and gas compression.
  • Offshore & Remote Platforms: With support for remote I/O up to 12 km, the TRICONEX 4310 is ideal for centralised control of widely spread assets on offshore platforms or pipeline stations.
Description
The TRICONEX 4310 serves as the central brain of the Tricon safety system, executing logic solving and communication management. Its enhanced design provides faster processing speeds and larger memory capacity than standard versions, supporting complex control strategies for emergency shutdown (ESD) and fire & gas (F&G) systems.

Built on a robust TMR architecture, the TRICONEX 4310 contains three independent microprocessor channels that simultaneously execute the same control program. A hardware-based "2-out-of-3" (2oo3) voting mechanism ensures that if one channel fails, the other two maintain correct output without process interruption.

The TRICONEX 4310 supports extensive I/O capabilities, managing up to 118 analog and digital I/O modules. It also enables remote I/O connections up to 12 kilometers from the main chassis, making it ideal for large-scale industrial facilities.
