TRICONEX 3674 Digital Output Module

TRICONEX 3674 Digital Output Module

Product Overview

The TRICONEX 3674 digital output module is a component designed for safety and automation systems. It is capable of converting digital signals from the control system into drive signals for the actual operating devices, thus enabling precise control of actuators, relays and other devices.

Main functions

Digital Signal Conversion: Converts digital signals from the control system into drive signals to control various operating devices.

Precise control: Provide precise control signal output to ensure stable operation and efficient operation of equipment.

Strong compatibility: It can be widely used in various industrial automation fields and is compatible with a variety of equipment and systems.

Application Areas

TRICONEX 3674 digital output module plays an important role in many fields, including but not limited to:

Chemical and petrochemical industry: used to control valves, pumps, heaters and other equipment to ensure the safety and stability of the chemical process.

Refineries: to control critical equipment and manage operational steps and safety interlock systems in the refining process.

Power plants: for controlling the start and stop of power generation equipment, opening and closing of circuit breakers and operation of other auxiliary equipment to ensure the reliability and safety of power production.

Power Distribution Systems: to control switches and circuit breakers in the power distribution network for automated power distribution and load management.

Water Treatment Plant: for controlling equipment such as pumps, valves and filters to ensure efficient and stable water treatment processes.

Wastewater treatment plants: to manage the operation of wastewater treatment plants, optimise the treatment process and ensure environmental compliance.

Drilling rigs and refineries: for controlling critical drilling and refining equipment to ensure the safety and efficiency of the production process.

Pipeline systems: to control pipeline valves and pressure regulating equipment, preventing leaks and optimising delivery efficiency.

In addition, TRICONEX 3674 is widely used in automated production lines, CNC machine tools, building management systems, fire and security systems, intelligent transport systems and infrastructure management.

Technical Features

Remote I/O function: TRICONEX 3674 is not only a digital output module, but also has a remote I/O function that can execute local logic and reduce the processing burden of the host controller.

Intelligent MCC: Connecting devices such as PLCs, soft starters and VFDs via a digital network greatly reduces the amount of wiring and provides additional functions such as access to diagnostic data, controlled variable status and variable representation information.

High reliability: High-quality materials and manufacturing processes are used to ensure stable performance in a variety of harsh environments.

Installation and Maintenance

Installation: Please follow the installation guide in the product manual to ensure that the module is correctly installed and fixed to the appropriate position.

Maintenance: Regularly inspect and maintain the TRICONEX 3674 to ensure that it shows no signs of damage or aging. If a fault is found, replace and reconfigure the system.

Controller Features

• Provides Triple Modular Redundant (TMR) architecture, whereby each of  three identical channels independently executes the application, and  specialized hardware and software mechanisms vote all inputs and outputs. 

• Withstands harsh industrial environments. 

• Integrates the I⁄O module with the termination assembly. 

• Enables field installation and repair to be done at the module level while the  controller remains online without disturbing field wiring. 

• Supports up to 14 I⁄O modules. (If the controller includes AO or PI  Modules, up to 10 modules are supported.) 

• Provides TriStation and Modbus communication directly from the Main  Processor (MP) or from the Communication Module (CM). 

• Executes applications developed and debugged using TriStation. 

• Provides a dedicated co-processor which controls the input and output  modules to reduce the workload of the MP. Each I⁄O module is supported by  custom application-specific integrated circuits (ASICs), which scan inputs  and perform diagnostics to detect hardware faults. Output module ASICs do  the following: 

– Supply information for voting of output data.

– Check I⁄O loop-back data from the output terminal for final validation of  the output state. 

– Perform diagnostics to detect hardware and field-wiring problems. 

• Provides integral online diagnostics with adaptive-repair capabilities. 

• Allows normal maintenance while the controller is operating, without  disturbing the controlled process. 

• Supports hot-spare I⁄O modules for critical applications for which prompt  service may not be possible. 

• Provides integral support for redundant field and logic power sources.
