Description
The TRICONEX 3721 is a Triple Modular Redundant (TMR) Analog Input Module used in safety-critical applications within the Triconex Triconex Trident Safety Instrumented System (SIS). It provides a high-integrity analog input solution for monitoring critical process parameters in various industries.
Key Features:
- Triple Modular Redundancy (TMR): Employs a TMR architecture with three independent analog input channels, ensuring continuous operation even if one channel fails.
- Fault Detection and Isolation (FDI): Continuously monitors the health of each channel and isolates faulty channels, preventing erroneous data from affecting the control system.
- High Accuracy: Provides high-accuracy analog-to-digital conversion for precise measurement of process variables.
- Wide Input Range: Supports a wide range of analog input signals, including voltage, current, and RTD (Resistance Temperature Detector) inputs.
- Communication Options: Includes communication options, such as Modbus and Profibus, for integration into control and safety systems.
Applications:
- Safety-Critical Process Control: The 3721 is specifically designed for safety-critical process control applications, where system failures can have catastrophic consequences. It is commonly used in:
- Chemical processing plants: Monitoring critical parameters like temperature, pressure, and flow in hazardous environments.
- Oil and gas refineries: Ensuring safe operation of pipelines, distillation columns, and other process equipment.
- Power generation plants: Protecting critical components like turbines, boilers, and generators.
- Nuclear power plants: Monitoring safety-related parameters in nuclear reactors and associated systems.
