The Triconex 3506X is a high - performance digital input module applied in industrial automation and control systems. Here are the details:
- Basic Information
- Manufacturer: Schneider Electric (formerly Triconex).
- Model: DI 3506X.
- Module Type: High - density digital input module.
- Function: It is a 32 - channel isolated digital input module for safety systems, compatible with Tricon V9, V10, V11 safety systems.
- Technical Specifications
- Input Channels: It has 32 individually isolated digital input channels.
- Input Signal Type: It supports dry contact (form A/form B relays) and wet contact (24 VDC).
- Input Voltage Range: The nominal input voltage is 24 VDC, and it is compatible with 12 - 48 VDC (with external conditioning).
- Input Current: The typical input current is about 5 - 10 mA per channel.
- Isolation: The channel - to - channel isolation voltage is 500 VAC, and the field - to - backplane isolation voltage is 1500 VAC.
- Response Time: It is less than 10 ms (with a configurable debounce filter).
- Update Rate: It is synchronized with the Tricon scan time.
- Power Supply: It is backplane - powered, getting 5 VDC from the Tricon chassis, and the typical power consumption is about 2 W.
- Product Features
- Diagnostics Function: Each channel is equipped with LED indicators. The green one indicates the input is active, and the red one indicates a fault or error. The module also has status LEDs for power, communication, and fault. It has built - in diagnostics for open - wire and short - circuit detection.
- Safety Certification: It is certified to IEC 61508 (SIL 3), and approved by TÜV Rheinland. It also has industrial certifications such as ATEX/IECEx (for hazardous areas), CE, UL, and CSA.
- Triple Modular Redundancy (TMR): It adopts the TMR technology, which has three isolated and parallel control systems and extensive diagnostics integrated into one system, improving the reliability and safety of the system.
- Operating Environment
- Operating Temperature: - 40 °C to + 70 °C.
- Storage Temperature: - 40 °C to + 85 °C.
- Humidity: 5% to 95% (non - condensing).
- Vibration/Shock Resistance: It complies with IEC 60068 - 2 - 6/27.
- Mechanical Specifications
- Dimensions: Standard Tricon module size (fits 9 U/15 U chassis).
- Weight: About 0.5 kg.
- Mounting: It is hot - swappable, which supports online replacement.
- Typical Applications
- Emergency Shutdown Systems (ESD): Used to ensure the safe shutdown of the system in case of emergencies.
- Fire and Gas Detection Systems (FGS): Monitors the occurrence of fire and gas leakage and triggers corresponding protection actions.
- Turbine Control Systems: Controls the operation of turbines to ensure their stable and efficient operation.
- Process Safety Monitoring: Monitors the safety status of industrial processes to prevent accidents.
