Description
Product Description
The Triconex 3805E is an enhanced analog output PLC module designed for use in safety – critical applications9. It is a high – performance, high – reliability module9. The 3805E provides eight independent analog output channels, each of which is capable of driving a variety of loads, including actuators, valves, and solenoids9. It receives output signals from the main processor module on each of three channels. Each set of data is then voted and a healthy channel is selected to drive the eight outputs. The module monitors its own current outputs and maintains an internal voltage reference to provide self – calibration and module health information.

- Output accuracy: <0.25% (in the range of 4 – 20 mA) of FSR (0 – 21.2 mA), from 32°F to 140°F (0°C to 60°C)
- Over – range protection: +42.5 VDC, continuous
- Switch time on leg failure: <10 ms, typical
- Power supply: 120/240 VAC or 24 VDC9
- Operating temperature: – 40°C to +70°C9
- Communication interface: RS – 485 Modbus RTU13
Advantages and Characteristics
- High reliability: The 3805E has a redundant design that includes dual microprocessors, dual power supplies, and dual communication ports9. This ensures that the module will continue to operate even if one of its components fails9. It also has built – in diagnostics that continuously monitor the module’s health, detecting any problems with the hardware or software and reporting them to the control system9.
- Precise control: With a 12 – bit resolution and high – accuracy output, the 3805E can provide precise analog control signals, which is crucial for applications that require accurate regulation of process parameters.
- Fail – safe operation: The module is designed to fail in a safe state, driving its outputs to a safe value in case of failure, helping to prevent accidents and protect personnel and equipment9.
Application Areas and Application Cases
- Application areas: The Triconex 3805E is widely used in industries such as oil and gas, chemical processing, power generation, and manufacturing. It is suitable for safety – critical applications that require high – reliability analog output control, such as controlling the flow of fluids in pipelines, regulating the temperature of reactors, and controlling the speed of motors.
- Application case: In a chemical plant, the Triconex 3805E is used to control the opening and closing of valves that regulate the flow of raw materials into reactors. The precise control provided by the 3805E ensures that the correct amount of raw materials is added to the reactors, maintaining the stability and safety of the chemical reaction process.
Competitor Comparison
Compared with similar products, the Triconex 3805E stands out in terms of reliability and safety. Its triple – modular redundant design and fail – safe operation features provide higher levels of protection and stability in critical applications. It also offers better accuracy and resolution, enabling more precise control of process parameters. Additionally, the 3805E has a wider operating temperature range, making it suitable for use in harsh industrial environments.
Selection Recommendations
- Compatibility: Ensure that the Triconex 3805E is compatible with your existing control system, including the main processor module and other related components.
- Installation environment: Consider the installation location and environmental conditions, such as temperature, humidity, and vibration. The 3805E is designed to operate in harsh industrial environments, but it is still necessary to ensure that the installation environment meets its operating requirements.
- Budget: The Triconex 3805E is a high – quality and high – reliability module, and its price may be relatively higher than some other products. When selecting, it is necessary to consider your budget and balance the performance and cost.
Precautions
- Safety regulations: When installing and using the Triconex 3805E, follow relevant safety regulations and standards to ensure the safety of personnel and equipment.
- Maintenance suggestions: Regularly check the module’s operating status and perform necessary maintenance and calibration. Clean the module regularly to prevent dust and dirt from affecting its performance. In case of any faults or abnormalities, promptly contact the manufacturer or a professional maintenance team for repair.
