TRICONEX 3700 Safety Instrumented System

The Triconex 3700 is part of the Triconex Safety Instrumented System (SIS) by Schneider Electric, designed for high-integrity safety applications. Below are the key technical parameters for the Triconex 3700 series (which includes models like 3700E, 3700A, etc.):

General Technical Specifications:

1. Type: Triple Modular Redundant (TMR) Safety System

2. Safety Certification:

• • SIL 3 (IEC 61508, IEC 61511)
  • TÜV Certified

3. Processor:

• • 32-bit RISC-based processors (TMR architecture)

4. Memory:

• • Flash & SRAM for program storage

5. Communication Ports:

• • Ethernet/IP (for integration with control systems)
  • Modbus TCP/IP
  • TriStation (for programming & diagnostics)

6. I/O Modules:

• • Supports digital & analog I/O (redundant or TMR configurations)
  • Hot-swappable modules for maintenance

7. Power Supply:

• • 24V DC (typical)
  • Redundant power supply options available

8. Operating Temperature:

• • 0°C to 60°C (32°F to 140°F)

9. Humidity:

• • 5% to 95% (non-condensing)

10. MTBF (Mean Time Between Failures):

• • Typically > 100 years (due to TMR redundancy)

11. Fault Tolerance:

• • 2-out-of-3 (2oo3) voting logic for high availability

Key Features:

• High Availability & Fault Tolerance (TMR architecture ensures no single point of failure)
• Online Diagnostics & Repair (hot-swappable modules)
• Cyber Security Features (secure communication protocols)
• Backward Compatibility with older Triconex systems

Typical Applications:

• Emergency Shutdown Systems (ESD)
• Fire & Gas Systems (FGS)
• Turbine Control
• Critical Process Safety
