Triconex 3625 Triple Module Redundant architecture module

Triconex 3625 Triple Module Redundant architecture module

Product Overview

The Triconex 3625 module is designed based on the Triple Module Redundancy (TMR) architecture. It can convert the digital signals of the control system into analog signals and output them to the field actuators, such as control valves and frequency converters, to achieve precise process control and ensure the stable and reliable operation of the system even under harsh working conditions.

Key characteristics

Triple redundancy architecture: The module is equipped with three independent processing channels inside, and each channel can independently process the input data and output analog signals. A three-out of two voting mechanism is adopted, that is, only when the output results of at least two of the three channels are consistent will the result be regarded as the final output. This design greatly enhances the fault tolerance of the system. Even if a single channel fails, the system can continue to operate normally, reducing production interruptions or safety accidents caused by module failures.

High-precision output: It can provide high-precision analog output. Common output signal types include 4-20mA current signal, 0-10V voltage signal, etc., which can meet the input signal requirements of different field devices. It has a relatively high resolution, generally up to 16 bits or even higher, which can precisely control the actuator, achieve fine process regulation, and ensure that all parameters in the industrial production process remain stable within the set range.

Wide range of working conditions: It has good environmental adaptability, with a general operating temperature range of -40℃ to +75℃, and can operate reliably in harsh environments such as high and low temperatures. At the same time, it also has a strong tolerance to humidity, vibration, electromagnetic interference, etc., meeting the complex working environment requirements of industrial sites.

Fault diagnosis and self-monitoring: It is equipped with a complete fault diagnosis function, which can monitor the working status of the module itself and the signal conditions of the output channel in real time. It can quickly detect faults such as channel short circuit, open circuit and over-range, and promptly feedback fault information through indicator lights, communication interfaces and other means, facilitating maintenance personnel to quickly locate and eliminate faults and improving the maintainability of the system.

Communication capability: Supports multiple industrial communication protocols, such as Modbus, Profibus, Ethernet/IP, etc., facilitating data interaction and integration with other controllers and upper computer monitoring systems, achieving remote configuration, monitoring and control, and facilitating centralized management of the entire control system by operators.

Technical parameters

Number of channels: Usually 8 or 16 analog output channels (depending on the model).

Output type: Supports multiple analog output signal types such as 4-20mA, 0-5V, 0-10V, ±5V, ±10V, etc.

Output accuracy: Throughout the entire output range, the accuracy can generally reach ±0.1% or higher.

Response time: The output response speed is relatively fast, capable of converting digital signals into analog signals within a short period of time (usually within tens of milliseconds) to meet the requirements of real-time control.

Isolation voltage: There is a relatively high isolation voltage between channels and between channels and the system ground, generally 2500VDC or above, which effectively enhances electrical safety and anti-interference capability.

Power consumption: The power consumption is relatively low, with typical values generally less than 10W (the specific value varies by model), which helps to reduce the overall energy consumption of the system.

Application scenarios

In the petrochemical industry, in the processes of petroleum refining and chemical production, it is used to control the opening degree of the feed valve of the reaction vessel, adjust the reflux ratio of the distillation column, and control the fuel flow of the heating furnace, etc. Through precise analog output control, it ensures the stability and efficiency of the production process, and guarantees product quality and production safety.

Power industry: In power plants, it can be used to regulate the excitation current of generators and control the stability of output voltage. It can also control the opening degree of the steam inlet valve of the steam turbine and adjust the power output of the unit. In substations, it is used to control the switching of capacitor banks, regulate reactive power, and maintain the stability of grid voltage.

Metallurgical industry: In the process of steel smelting, controlling the coal injection volume of blast furnaces, regulating the oxygen flow rate of converters, and controlling the billet pulling speed of continuous casting machines, etc. In the smelting of non-ferrous metals, precisely controlling parameters such as current and voltage in electrolytic cells can enhance the quality of metal products and production efficiency.

In the pharmaceutical and food industries: During the production processes of pharmaceuticals and food, parameters such as temperature, pressure, and liquid level of reaction vessels and fermentation tanks, as well as the operating speed of various equipment on the production line, are controlled to ensure that the production process meets the process requirements and quality standards.
