TRICONEX 3005 Digital input module

TRICONEX 3005 Digital input module

I. Oil and Gas Extraction and ProcessingCore Application Scenarios

• Drilling Platform Safety Monitoring: Collects switch signals from wellhead pressure sensors and combustible gas detectors in real time, and connects to the SIS (Safety Instrumented System) to enable emergency shutdown (ESD) control.

• Oil and Gas Pipeline Monitoring: Detects the status of pipeline valves (open/close) and flow switch signals, and ensures fast interlock protection for long-distance pipelines during leaks through the TRICONEX fault-tolerant system.

Technical Adaptability

• Wide-temperature design (-40°C to +85°C) adapts to high-temperature and high-humidity environments on offshore platforms, and salt fog corrosion-resistant coatings meet marine engineering requirements.

• 16-channel isolation design avoids signal interference, ensuring accurate transmission of combustible gas alarm signals (e.g., interlock actions when H2S concentration exceeds the limit).

• 
  

II. Chemical and Petrochemical Production UnitsCore Application Scenarios

• Reactor Safety Control: Collects digital signals from temperature switches and pressure transmitters, and coordinates the logic for safety pressure relief valves (PSV) and agitator shutdown to prevent over-temperature explosions.

• Storage Tank Fire Interlock: Monitors the status of flame detectors and level switches, triggers the activation of sprinkler systems and the closure of emergency shutdown valves for storage tanks, meeting the SIL3 safety integrity level requirements.

Technical Advantages

• ATEX certification supports installation in hazardous areas (such as Zone 1 explosive environments), and the module's fail-safe design ensures safe output states during power outages.

• A response time of less than 1ms meets the fast interlock requirements of chemical processes (e.g., emergency shutdown of ethylene cracking furnaces).

• 
  

III. Power and Energy Production SystemsCore Application Scenarios

• Key Equipment Monitoring in Nuclear Power Plants: Collects temperature switch signals from reactor pressure vessels and overspeed protection sensors for steam turbines, and connects to the Tricon triple fault-tolerant system to achieve safety-level control.

• Gas Turbine Protection System: Monitors the status of vibration switches and shaft displacement sensors, triggers trip logic to prevent equipment damage, and complies with the ISO 10884 mechanical safety standard.

Key Features

• Anti-electromagnetic interference (EMI) design adapts to the electromagnetic environment of high-voltage equipment in substations, ensuring no false operation of relay protection signals.

• Hot-swappable functionality supports online maintenance, avoiding power system downtime (e.g., replacing faulty channels while generator sets are in operation).

• 
  

IV. Metallurgy and Iron & Steel IndustryCore Application Scenarios

• Blast Furnace Top Equipment Control: Collects material level switch and pressure equalizing valve status signals, coordinates the logic for burden distributor actions, and prevents gas leakage from the furnace top.

• Continuous Casting Machine Emergency Shutdown System: Monitors mold level switches and straightener overload signals, quickly cuts off the casting process, and avoids steel leakage accidents.

Environmental Adaptability

• Vibration resistance (50G impact) adapts to mechanical vibrations during rolling mill operation, and wide-temperature performance meets the high-temperature environment beside heating furnaces (up to 85°C).

• Redundant power input design (dual 24VDC power supplies) prevents signal loss caused by power grid fluctuations in metallurgical workshops.

• 
  

V. Rail Transit and Tunnel EngineeringCore Application Scenarios

• Subway Tunnel Fire Alarm: Collects digital signals from smoke detectors and temperature sensors, coordinates the start/stop of tunnel fans and evacuation indicator systems, and complies with the EN 50156 rail traffic safety standard.

• High-Speed Railway Traction Converter Monitoring: Detects over-temperature protection signals for IGBT modules and circuit breaker status, and connects to the train TCMS (Train Control and Management System) to achieve fault early warning.

Functional Highlights

• Complies with the EN 61373 railway vehicle impact and vibration standard, ensuring module stability during train operation.

• Real-time channel status display via LEDs facilitates quick fault location for maintenance personnel in tunnel equipment (e.g., signal collection points in underground stations).

• 
  

VI. Pharmaceutical and Food Sterile ProductionCore Application Scenarios

• Sterile Filling Line Status Monitoring: Collects sealing detection switch signals for filling heads and pressure switch signals for sterilization kettles, ensuring compliance with GMP (Good Manufacturing Practice) standards.

• Food Processing Equipment Safety Interlock: Monitors limit switch status for sterilization kettle doors and emergency stop buttons on conveyor belts, preventing safety accidents caused by human error.

Compliance Design

• Housing materials comply with FDA food contact standards, featuring smooth surfaces for easy cleaning, adapting to CIP (Clean-in-Place) requirements in pharmaceutical workshops.

• Module fault diagnosis functionality supports electronic signatures and audit trails, meeting data integrity requirements in the pharmaceutical industry (e.g., 21 CFR Part 11).
