Triconex HCU3805E Triple Modular Redundant Analog Output Module

Description

• Superior Redundancy and Stability
  • The triple modular redundant structure makes three identical circuits operate in parallel. The module receives signals from the main processor module through three channels, conducts voting on the data, and selects a normal channel to drive the output, which greatly improves the reliability of the system.
  • It can still operate normally even if as many as two internal channels fail, and will not cause the overall downtime of the control link, which ensures the continuity of industrial production.
• Comprehensive Self-Diagnosis and Self-Calibration
  • It maintains an internal voltage reference to realize the self-calibration function, and each channel is equipped with a current loopback circuit that can independently verify the accuracy and existence of analog signals without being affected by load or channel selection.
  • It continuously performs diagnostic operations on each internal channel and circuit. When a fault is detected, the faulty channel will be deactivated immediately, the fault indicator will be turned on, and the chassis alarm will be triggered at the same time to remind the staff to deal with it in time.
• Reliable Circuit and Power Protection
  • The design of the module can prevent unselected channels from driving analog signals to the on-site equipment, avoiding signal confusion and incorrect operation of the equipment.
  • It supports redundant loop power supply sources, and is equipped with independent power supply and fuse indicators. This design can prevent the entire module from stopping working due to a single power supply failure.
• Convenient Maintenance and Installation
  • It supports hot-spare capability, allowing online replacement of faulty modules without shutting down the entire system, minimizing production losses caused by maintenance.
  • The modular design not only facilitates the expansion of the number of output points according to the scale of the industrial project, but also makes daily inspection and part replacement more efficient.

• Oil and Gas Industry
  • In onshore and offshore drilling platforms, it connects with the control system and drives the valves on the oil and gas transmission pipelines. By adjusting the opening of the valves according to the analog signals, it precisely controls the oil and gas transmission flow and ensures the safety and efficiency of the drilling operation.
  • In natural gas processing plants, it is used to drive the actuators of compression equipment, and adjusts the operating parameters of the equipment according to the system instructions to maintain the stability of the gas pressure during the processing.
• Chemical Industry
  • In the cracking units of large petrochemical enterprises, it is used as a core control component to control the actuators related to the cracking furnace. It ensures that the cracking reaction proceeds under the optimal process conditions by precisely controlling parameters such as temperature and pressure of the cracking furnace.
  • In the production process of chemical raw materials, it drives the feeding pumps and discharge valves of the reaction kettles, and adjusts the feeding and discharge speed according to the system signals to maintain the stability of the reaction process and avoid safety accidents caused by improper control.
• Power Industry
  • In thermal power plants, it is integrated into the control system of boilers and steam turbines. It drives the actuators of fuel supply pipelines and air intake valves, adjusts the fuel supply and air intake volume according to the operating parameters of the equipment, and ensures the stable output of the power generation system.
  • In nuclear power plants, it is applied to the auxiliary control systems such as the reactor cooling system. It drives the related pump and valve actuators to ensure the stable operation of the cooling system and provides a guarantee for the safe operation of the reactor.
• Pharmaceutical and Food Processing Industry
  • In pharmaceutical production lines, it is used to control the actuators of mixing tanks and distillation equipment. It precisely adjusts the operation state of the equipment through converted analog signals to ensure that each production link meets the strict quality and safety standards of the pharmaceutical industry.
  • In food and beverage processing plants, it drives the flow control valves of material conveying pipelines and the speed-regulating actuators of mixing equipment, ensuring the accuracy of material proportioning and the stability of the processing process, and improving the consistency of product quality.
