TRICONEX 3708EN

The Triconex 3708E/3708EN is a Main Processor Module for the Tricon v9/v10/v11 Safety Instrumented System (SIS) by Schneider Electric. It is the brain of the Tricon system, executing safety logic and managing I/O communications.

Triconex 3708E/3708EN Technical Parameters

General Specifications:

• Manufacturer: Triconex (Schneider Electric)
• Model: 3708E (Standard) / 3708EN (Enhanced)
• Type: Main Processor Module (MPM)
• Function: Executes Triple Modular Redundant (TMR) safety logic and controls I/O modules.
• Safety Integrity Level (SIL): SIL 3 (IEC 61508 / IEC 61511)

Processor & Performance:

• Architecture: Triple Modular Redundancy (TMR) – Three independent 32-bit processors running in parallel.
• Processor Speed:
  • 3708E: ~25 MHz
  • 3708EN: Faster processing (exact speed depends on firmware)
• Memory:
  • RAM: 8 MB (expandable)
  • Flash Memory: For firmware and application storage
• Scan Time: Typically 10-50 ms (depends on logic complexity)

Communication & Interfaces:

• Backplane Communication:
  • Controls and monitors Tricon I/O modules (e.g., 3503E, 3664, 4351B).
  • Supports hot-swappable module replacement.
• External Communication:
  • TriStation 1131 (for programming & configuration)
  • Modbus TCP/IP, OPC (via communication modules like 8101/8102)
  • Peer-to-Peer (via 4009 module, if used)

Redundancy & Fault Tolerance:

• TMR Architecture: Three independent channels with 2-out-of-3 (2oo3) voting for fault tolerance.
• Fault Detection:
  • Continuous self-testing (watchdog timers, memory checks).
  • Automatic failover if a fault is detected.

Environmental & Mechanical:

• Operating Temperature: -40°C to +70°C (-40°F to +158°F)
• Humidity: 5% to 95% (non-condensing)
• Mounting: Installed in Tricon chassis (e.g., 3008, 3009).
• Certifications:
  • ATEX / IECEx (for hazardous areas, if applicable)
  • UL, CE, cUL, TÜV

Power Requirements:

• Voltage: 5V DC (supplied via Tricon backplane)
• Power Consumption: ~10W (varies based on configuration)

Typical Applications:

• Emergency Shutdown Systems (ESD)
• Fire & Gas Systems (F&G)
• Turbomachinery Control (TMC)
• Critical process safety in oil & gas, chemical, power plants.
