TRICONEX 8312 execution control module

Basic features: TRICONEX 8312 is an intelligent executive control module. It usually adopts a compact design and can be conveniently installed in a standard industrial control cabinet. It supports multiple installation methods, such as DIN rail installation, etc., and can adapt to different industrial environments.

Redundant design: Inherits the typical three-mode redundancy (TMR) technology of TRICONEX products. There are three independent processors and related circuits inside the module, which process the input signals simultaneously and ensure the accuracy and reliability of the output results through a voting mechanism. Even if one of the processors or related circuits malfunctions, it will not affect the normal operation of the module, greatly enhancing the fault tolerance and stability of the system. It is suitable for industrial applications with extremely high reliability requirements, such as the petrochemical and power industries.

Signal processing capability: Equipped with a rich array of input and output interfaces, it can handle various types of signals. It can receive analog input signals, such as 4-20mA or 0-10V signals from temperature, pressure, flow sensors, etc., and can also process digital input signals, such as switch status signals. Meanwhile, analog signals can be output according to the control logic to control actuators such as control valves, or digital signals can be output to control devices such as relays and solenoid valves, achieving precise control of industrial processes.

Communication function: It supports multiple industrial communication protocols, such as Modbus, Profibus, etc., and can communicate with other control devices, PLCS, upper computers, etc., facilitating integration into complex industrial automation control systems to achieve data transmission and sharing. This makes it easy for operators to remotely monitor and control the operating status of the module, as well as set and adjust parameters.

Diagnostic function: The module is equipped with a self-diagnostic function, which can monitor its own working status in real time, including processor status, power supply status, communication status, etc. When a fault is detected, an alarm signal will be sent out through the indicator light on the module or the communication interface, facilitating maintenance personnel to quickly locate and eliminate the fault, reducing system downtime and improving production efficiency.

Programming and configuration: Programming and configuration can be carried out through dedicated programming software. Users can flexibly set control logic, parameters, etc. according to specific process requirements to achieve personalized control needs. The module supports online programming and configuration, allowing for parameter modification and program update without downtime, which enhances the flexibility and maintainability of the system.

Application field

Control of oil refining and chemical plants

Application scenarios: Real-time control of core equipment such as atmospheric and vacuum distillation units, catalytic cracking units, and ethylene cracking furnaces.

Functional value: By precisely adjusting process parameters such as temperature, pressure, and flow rate, it ensures the stability of the reaction process and avoids safety accidents caused by control deviations (such as overpressure and leakage). It supports linkage with the safety instrument system (SIS) to quickly execute the emergency shutdown (ESD) logic in case of abnormality.

The field of electricity and new energy

Application scenarios: Grid connection control of steam turbine speed regulation systems in thermal power plants and photovoltaic inverters (with dedicated interfaces required).

Functional value: In thermal power units, it receives the speed signal and outputs the regulation signal to the servo valve to maintain the stability of the steam turbine speed. In the new energy scenario, the stability of grid connection is ensured by precisely controlling the output of the inverter.

Aseptic production process control

Application scenarios: Temperature control of fermentation tanks in vaccine production lines, pressure/flow regulation of aseptic filling lines.

Functional value: Meets the requirements of GMP (Good Manufacturing Practice) for equipment reliability and avoids abnormal batch product quality caused by control module failure. Support online parameter adjustment to adapt to process switching of different products.

Process control of steel smelting

Application scenarios: Furnace temperature control in blast furnace ironmaking, adjustment of pulling speed in continuous casting machines.

Functional value: It can operate stably in high-temperature and strong electromagnetic interference environments, adjust the cooling water flow and fuel supply in real time, and ensure the accuracy of smelting process parameters. Reduce the production halt losses caused by module failures through redundant design.

Offshore platform safety system

Application scenarios: Blowout preventer control on drilling platforms, fire and gas detection and execution of FPsos (Floating Production Storage Units).

Functional value: Maintain high reliability in damp and salt spray corrosive Marine environments, support remote communication with underwater equipment, respond quickly to emergencies such as blowouts, and execute shutdown logic. Sewage treatment and water supply and drainage

Application scenarios: Dissolved oxygen control in aeration tanks of sewage treatment plants, variable frequency regulation of pumps in urban water supply systems.

Functional value: By real-time monitoring of water quality parameters (such as COD and pH value), the flow rate of the dosing pump can be adjusted. In the water supply system, the speed of the water pump is automatically adjusted according to the water consumption to achieve energy-saving operation.
