Triconex EPI3382 Digital Output Module for Safety Instrumented Systems

Description

• Communication Specifications
  • It supports multiple communication protocols including Modbus, TCP/IP and Ethernet/IP, which can realize data transmission and command interaction with different types of industrial equipment and upper monitoring systems.
  • The standardized communication interface design ensures that there is no need to redevelop the communication program during system integration, reducing the difficulty of system construction.

• Dual Signal Processing Capability
  • It mainly undertakes the digital output task, providing stable digital signals to control external equipment such as industrial valves, actuators and alarm devices, and ensuring the accurate execution of on-site control commands.
  • With 8-channel analog input and output functions, it can process analog signals such as temperature and pressure collected on site, expanding its application scope in complex industrial control scenarios that require both digital and analog control.
• Redundancy Ensures Continuous Operation
  • The triple modular redundancy design is adopted. When a certain component inside the module fails, the other two redundant components can immediately take over the work.
  • This design avoids system downtime caused by module failure, ensuring the uninterrupted operation of the safety instrumented system and effectively reducing production losses caused by equipment failure.
• Flexible Configuration and Easy Integration
  • Users can flexibly configure input and output channels according to actual industrial control needs, and select appropriate communication protocols to match different upper system and on-site equipment requirements.
  • The compact structural design and standardized installation interface enable it to be quickly installed in the Triconex system chassis, and it can be integrated into the existing control system without major modifications to the original system.
• Energy-saving and Stable Operation
  • The maximum power consumption is only 10 watts, which has excellent energy-saving performance. When a large number of modules are used in the system, it can significantly reduce the overall energy consumption of the system and reduce the operating cost of the enterprise.
  • The wide voltage working range of 18 – 36VDC makes it not affected by the fluctuation of the on-site power supply, and ensures stable output of control signals even in the case of unstable power supply.

• Oil and Gas Industry
  • It is used in the safety interlocking system of offshore drilling platforms. It outputs digital signals to control the opening and closing of wellhead valves. When abnormal pressure is detected, it can immediately trigger the valve closing command to prevent oil and gas leakage.
  • In long-distance oil and gas transmission pipelines, it cooperates with the leakage monitoring system. Once a leakage point is found, it sends signals to start the emergency shutdown device and the alarm system to avoid large-scale environmental pollution and safety accidents.
• Chemical and Pharmaceutical Industry
  • In chemical production workshops, it controls the feeding equipment and discharge valves of reaction kettles. According to the instructions of the upper system, it outputs stable signals to accurately control the feeding amount and discharge speed, ensuring the stability of the chemical reaction process.
  • In pharmaceutical production lines that require strict process control, it is used to monitor and control the temperature and pressure of drug synthesis equipment, and controls the operation of heating and pressure relief devices through signal output to ensure the quality and production safety of drugs.
• Power Industry
  • In thermal power plants, it is integrated into the boiler safety control system. When the boiler pressure or temperature exceeds the safety threshold, it outputs control signals to adjust the fuel supply device and air intake mechanism, or triggers an emergency shutdown to avoid boiler explosion accidents.
  • In hydropower stations, it is used to control the opening and closing of water turbine guide vanes. Through stable digital signal output, it adjusts the water flow entering the water turbine to realize the stable control of power generation power.
• Metallurgical Industry
  • In steel plant blast furnace systems, it controls the cooling water circulation equipment. It outputs signals to adjust the water pump speed according to the furnace temperature signal, ensuring that the blast furnace is always in a safe temperature range and preventing equipment damage due to overheating.
  • In non-ferrous metal smelting processes, it controls the alarm and emergency cooling systems. When the smelting temperature is abnormal, it immediately sends an alarm signal and starts the cooling device to ensure the safety of the smelting process and equipment.
