Description
The code “TRICONEX 3805E” refers to an industrial process control module manufactured by Invensys (now part of Schneider Electric). Here’s a breakdown of the product details:
Product Name:
- Invensys Triconex 3805E Analog Output Module
Product Description:
The Triconex 3805E is a module used in industrial process control systems, particularly within safety instrumented systems (SIS) for critical applications. It functions as an analog output module, providing a controlled electrical current signal to various process control elements.
Product Function:
The Triconex 3805E performs the following tasks within a process control system:
- Analog Signal Output: It receives a digital control signal from the SIS controller and converts it into a proportional analog current signal (typically 4-20 mA).
- Signal Isolation: The module isolates the internal control signal from the output current loop, ensuring safety and preventing ground loops that could affect signal integrity.
- Fault Detection and Diagnostics: The 3805E continuously monitors its health and the output current for potential faults. It can detect issues like open circuits, short circuits, or signal errors and report them to the SIS controller for corrective actions.
- Safe Operation: The module incorporates safety features to ensure reliable operation in safety-critical applications. These features might include redundancy, self-diagnostics, and fail-safe modes.
Process Control Applications:
The Triconex 3805E can be used to control various process elements based on the received control signal from the SIS controller. Here are some examples:
- Control Valves: Regulating the flow of fluids or gases within a process.
- Variable Speed Drives: Adjusting the speed of motors driving critical equipment.
- Alarms and Indicators: Providing output signals to activate alarms or indicator lights based on safety conditions.
Product Parameters and Specifications (Refer to Schneider Electric website or datasheet for details):
Exact specifications may vary depending on the revision of the Triconex 3805E module. However, some typical parameters might include:
- Output Current Range: The range of analog current output the module can provide (e.g., 4-20 mA).
- Output Accuracy: The level of precision in maintaining the desired current output based on the control signal.
- Response Time: The time it takes for the module to respond to changes in the control signal and adjust the output current.
- Communication Interface: The method used for receiving control signals from the SIS controller (e.g., Triconex communication protocol).
- Safety Certifications: Certifications by regulatory bodies for use in safety instrumented systems (e.g., IEC 61508).
Finding More Information:
