Triconex 3805E Enhanced Triple Modular Redundancy Analog Output Module

Product Short Description

Technical Specifications

Electrical Parameters
- Output Configuration: Equipped with 8 DC-coupled analog output channels with a commoned return, focusing on 4 – 20mA current output and supporting a +6% over-range capacity that expands the output range to 2 – 21.2mA.
- Resolution and Accuracy: Boasts 12-bit resolution to guarantee stable signal conversion quality. The output accuracy is less than 0.25% of the full-scale range within the temperature range of 0°C to 60°C, which ensures precise control of actuators.
- Power Supply Parameters: Operates with a nominal 24VDC power supply and is reverse voltage protected. It can continuously withstand a maximum external loop power of 42.5VDC, and different load resistances have specific voltage requirements, such as needing more than 20V for a 250Ω load and more than 35V for a 1000Ω load, with a minimum current of 1A for all these load conditions.
- Fault Response Speed: The typical switch time on channel failure is 10ms, and the maximum does not exceed 20ms, enabling rapid response to abnormal channel conditions.
- Status Indicators: Equipped with indicators for module status, showing pass, fault, active, and load states, as well as loop power status indicators that detect the presence of loop power above 20VDC.

Description

- Physical Parameters
  - Dimensions and Weight: The module weighs approximately 2.2 kilograms, and its compact structure with dimensions around 150mm×100mm×30mm allows for easy installation in standard industrial control cabinets.
  - Housing Features: Adopts a pea green color-coded housing, which helps maintenance personnel quickly locate and identify the module among numerous equipment components.
- Environmental Parameters
  - Operating Temperature: Maintains stable performance within the range of -40°C to 70°C, adapting to both low-temperature outdoor and high-temperature workshop environments.
  - Environmental Adaptability: Resists common electrical interference in industrial environments, and the isolated design between circuits further enhances its stability in complex electromagnetic environments.
Functional Features
- Triple Modular Redundancy for High Reliability: The triple modular redundancy design enables three independent circuit paths to process and transmit signals simultaneously. Even if one path malfunctions, the other two can continue to work normally, completely eliminating the impact of single-point faults and ensuring the continuous operation of the safety instrumented system.
- Precise Output and Strong Overload Protection: The module maintains high accuracy during signal conversion, and its 4 – 20mA standard current output is fully compatible with most industrial actuators. The continuous 42.5VDC over-range protection function effectively prevents module damage caused by sudden voltage surges in the loop, extending the service life of the module.
- Seamless Integration and Multi-Protocol Support: It supports multiple industrial communication protocols including Ethernet/IP, Modbus TCP/IP, and Profibus. This allows it to not only connect smoothly with Triconex controllers but also integrate with upper-level systems such as SCADA, realizing efficient data interaction between the module and the overall control system.
- Hot-Swap and Easy Maintenance: It supports hot-swap functionality, allowing maintenance personnel to replace the faulty module without shutting down the entire system, which minimizes production downtime. The clear status indicators facilitate quick troubleshooting of module operation problems and loop power issues.
- Stable Signal Transmission: With DC-coupled output design and excellent electrical stability, the module reduces signal loss and distortion during transmission. It ensures that the analog signals sent to the actuators accurately reflect the control instructions of the upper controller, thus realizing precise regulation of industrial process variables.
Application Scenarios
- Oil and Gas Industry: Deployed on offshore drilling platforms and onshore oil transmission pipelines, it converts control signals into 4 – 20mA current signals to regulate valves and pumps. When the system detects abnormal pressure or flow, it can quickly adjust the opening of valves to prevent oil and gas leakage and other major safety accidents.
- Petrochemical Industry: Installed on chemical reactors and distillation towers, it controls the feeding pumps and regulating valves in the production process. It accurately adjusts the flow of raw materials and the exhaust speed according to the system instructions, avoiding dangerous reactions caused by unstable process parameters and ensuring the stability of product quality.
- Power Industry: Used in thermal power plants and substations, it is responsible for controlling equipment such as transformer cooling systems and circuit breakers. It adjusts the operating status of the cooling system according to the temperature changes of the transformer, ensuring the transformer operates within a safe temperature range and maintaining the stable operation of the power grid.
- Metallurgical Industry: Applied to heating furnaces and cooling systems in steelmaking and smelting processes, it converts control signals into analog signals to regulate the fuel supply volume and cooling water flow. It precisely controls the smelting temperature, which improves the quality of metal products and protects the furnace body from damage due to excessive temperature.
- Pharmaceutical and Food Processing Industry: In pharmaceutical factories, it controls the valves and pumps in drug mixing and sterilization processes to ensure that parameters such as mixing speed and sterilization temperature meet production standards. In food processing plants, it regulates the speed of conveyor belts and the temperature of drying equipment, guaranteeing the consistency and safety of food products.
