Triconex HCU3700 Isolated Analog Input Module

Description

• Environmental and Physical Specifications
  • The working temperature range is – 40°C to 85°C, and the storage temperature range is – 55°C to 90°C, which can work stably in extremely cold and high – temperature industrial environments.
  • The overall dimensions are 194mm × 110mm × 50mm, and the weight is 1.2kg. The compact size is convenient for installation in dense control cabinets.
• Communication Specifications
  • It supports multiple communication protocols such as Modbus TCP/IP, RS – 232, RS – 485 and CANopen, which can realize data interaction with various industrial control devices and systems.
  • It is equipped with a HART interface, which can be connected with HART smart transmitters and other equipment to achieve two – way communication while collecting signals.

• Reliable Isolation and Anti – Interference Performance
  • It adopts channel – to – channel isolation design, with a typical channel – to – channel isolation resistance of 200kΩ, which can prevent signal crosstalk between different input channels.
  • The common mode rejection ratio can reach – 80dB in the range of DC – 100Hz, and it has input over – range protection of 150V DC continuous and 115V AC continuous, which can resist harsh industrial electromagnetic interference.
• Comprehensive Self – Diagnosis and Fault Tolerance
  • It provides complete and continuous diagnostic functions for each input channel. When a fault occurs in a channel, the module’s fault indicator will be activated immediately, and the backplane alarm signal will be triggered at the same time.
  • It can operate normally with up to two faulty channels, and supports online replacement of faulty modules, which minimizes system downtime caused by module failures.
• Strong Scalability and Compatibility
  • The modular design allows it to be flexibly combined with other I/O modules of the Triconex series. It can be expanded from small – scale systems with a few I/O points to large – scale systems with thousands of I/O points.
  • It is compatible with various general – purpose industrial instruments and upper – level control systems, and its support for multiple communication protocols and HART interfaces eliminates the need for a large number of adapter devices during system integration.
• Stable and Efficient Signal Processing
  • It uses a median selection algorithm in triple modular redundancy mode to select accurate data for each scan, ensuring the reliability of the transmitted data.
  • The minimum input change detection is 2% of the full scale, and the input change sampling period is 1 scan or 200ms (whichever is longer), which can accurately capture the subtle changes of on – site parameters.

• Nuclear Power Industry
  • It is applied to nuclear reactor protection systems to collect parameters such as temperature, pressure and water level of the reactor in real time. When parameters exceed the safe threshold, it can quickly send signals to trigger the emergency shutdown program to avoid nuclear safety accidents.
  • It is used in the monitoring of nuclear power plant auxiliary systems, such as the parameter collection of cooling water systems and pressure regulating devices, to ensure the stable operation of the entire nuclear power plant system.
• Oil and Gas Industry
  • In onshore and offshore drilling platforms, it connects with pressure transmitters and flow meters on pipelines to monitor key parameters such as oil and gas flow and pipeline pressure, and provides data support for the emergency shutdown system.
  • In natural gas processing and transportation stations, it collects data of gas compression equipment and transmission pipeline temperature, ensuring the safety and efficiency of the entire gas processing and transportation process.
• Chemical and Pharmaceutical Industry
  • In chemical reaction workshops, it monitors parameters such as temperature, pressure and material concentration in reactors. It transmits real – time data to the control system to adjust the feeding speed and reaction time and ensure the stability of chemical reactions.
  • In pharmaceutical production lines, it is used to collect parameters of mixing tanks and distillation equipment, ensuring that each production link meets the strict quality standards of the pharmaceutical industry.
• Power Industry
  • In thermal power plants, it is integrated into boiler and steam turbine control systems to collect parameters such as boiler flue gas temperature and steam pressure, and adjusts fuel supply according to the data to avoid equipment damage caused by abnormal parameters.
  • In substations, it monitors the operating parameters of transformers and high – voltage switchgear, and provides early warning for potential equipment failures through continuous data collection and analysis.
