Triconex 3674 Supervisory Digital Output Module

• Name: Triconex 3674 module is a supervisory digital output module.
• Voltage: 24V DC.
• Output Channels: It is a dual-channel output module with 32 output points.

• Triple Modular Redundancy (TMR): The Triconex system achieves fault tolerance through TMR. As part of the system, the 3674 module also features this structure. The module contains three identical branch circuits, each of which can independently execute control programs and work in parallel with the other two. It performs a “two-out-of-three voting” on the output data to ensure the accuracy and reliability of the output.
• Optoelectronic Isolation Technology: It adopts optoelectronic isolation technology to isolate the internal circuit of the module from the external circuit. This effectively prevents external interference signals from entering the module and also avoids interference from internal signals of the module to the external circuit, improving the stability and anti-interference ability of the system.

• High Reliability: Due to the adoption of triple modular redundancy structure and advanced fault diagnosis mechanism, it can still ensure the normal operation of the system when single or multiple components fail, reducing system downtime and improving the continuity and stability of the production process.
• Fault Diagnosis and Alarm: It has a powerful fault diagnosis function, which can monitor its own working status in real-time. Once a fault is detected, it will immediately send an alarm signal to notify the operator for processing. At the same time, it can accurately locate the fault position, facilitating maintenance personnel to carry out quick repairs.
• Flexible Configuration: It can be flexibly configured according to different application requirements to adapt to various complex industrial control scenarios. Users can set the output mode and working parameters of the module through programming software to meet specific control requirements.

• Power Industry: It is used in the control systems of power facilities such as power plants and substations to achieve precise control of equipment such as circuit breakers and disconnectors, ensuring the safe and stable operation of the power system.
• Petrochemical Industry: In processes such as oil extraction, oil refining, and chemical production, it controls various equipment such as pumps, valves, and compressors to ensure the automation and safety of the production process and prevent accidents such as leaks and explosions.
• Metallurgical Industry: It is applied in steel plants, non-ferrous metal smelters, etc., to control metallurgical equipment such as blast furnaces, converters, and continuous casters, improving production efficiency and product quality.
• Water Treatment Industry: In places such as waterworks and sewage treatment plants, it is used to control the operation of equipment such as water pumps and valves, realizing automatic control of the water quality treatment process and ensuring that the water quality meets the standards.
