Triconex TCM4351B Tricon Communication Module

Description

• Environmental Specifications
  • The operating temperature range is -40°C to +70°C, which can adapt to the extreme temperature changes of indoor and outdoor industrial sites such as cold northern workshops and high-temperature chemical plants.
  • It has strong environmental adaptability and can maintain stable communication performance even in industrial environments with large electromagnetic interference and mechanical vibration.

Functional Characteristics

• Diversified Communication Capabilities
  • It is equipped with four serial ports, two network ports and one debug port. Each serial port can be configured as a Modbus master or slave, and the first serial port supports Modbus or Trimble GPS interface, while the fourth serial port supports Modbus or Tristation interface.
  • It supports multiple protocols such as TCP/IP, Modbus TCP/IP, Tristation, SNT P and Jet Direct. The first network port also supports peer-to-peer and peer-to-peer time synchronization protocols to meet the interconnection needs of different devices.
• High Reliability Based on Redundant Architecture
  • The triple modular redundancy structure allows three identical functional units to work in parallel. When one unit fails, the other two can continue to maintain normal operation, and the faulty unit output is discarded to avoid communication interruption.
  • A single Tricon system can support up to four such modules, which can provide sixteen serial ports and eight Ethernet ports in total, realizing redundant configuration of communication links and improving the overall reliability of the system.
• Convenient Maintenance and Expansion
  • Although it does not have a hot – spare function, the faulty module can be replaced when the controller is running online, which avoids the production stop loss caused by system shutdown for maintenance.
  • Different modules of the same type can be assembled in the logical slots of the system. The modular design makes the later inspection of ports and circuits more convenient, and also provides convenience for the subsequent expansion of the communication system.

Application Scenarios

• Oil and Gas Industry
  • It is applied to refineries and natural gas processing plants to realize data transmission between the safety instrument system and on-site flow meters, pressure sensors and emergency shutdown valves, ensuring that the system can immediately receive fault signals and issue shutdown commands.
  • It is used in long-distance oil and gas pipeline control systems to connect the central controller with the remote valve stations and leak detection equipment along the pipeline, and transmit pipeline operation data and control commands in real time.
• Chemical and Nuclear Energy Industry
  • It is integrated into the control system of chemical reactors and distillation towers, and realizes data interaction between the DCS system and temperature, pressure and liquid level control equipment to ensure that the chemical reaction process is carried out within the set safety parameters.
  • It is deployed in the safety monitoring system of nuclear power plants, responsible for transmitting the data of radiation detectors, equipment operation status sensors and other devices to the central monitoring room, and ensuring the reliable transmission of safety control commands.
• Power Industry
  • It is used in the control and protection system of thermal power and hydropower plants to connect the turbine control system with the power grid scheduling equipment, realizing the real-time transmission of power generation data and scheduling instructions.
  • It is applied to the auxiliary control system of power transmission and transformation stations, communicating with the relay protection device and power quality monitoring equipment to ensure the stable operation of the power transmission and transformation network.
• General Industrial Automation
  • It is used in pharmaceutical production lines to connect the PLC and human – machine interface of the production equipment, transmitting the parameters of mixing, sterilization and filling processes to ensure that the production process complies with the norms.
  • It is integrated into the water treatment system, realizing data communication between the water quality detection sensor, water pump and valve control equipment, and ensuring the stability of the water purification and sewage treatment process.
