Main Features and Advantages
Triple Modular Redundancy (TMR)
The TRICONEX AI3351 leverages TRICONEX’s patented TMR technology, which triples all critical components within the module. This design ensures that if one of the redundant channels fails, the other two continue to operate, maintaining system integrity and availability. The built – in voting mechanism selects the correct data from the three redundant channels, eliminating the risk of single – point failures and providing a high level of fault tolerance in safety – instrumented systems.
High – Resolution and Fast Conversion
With a 16 – bit resolution, the AI3351 offers extremely accurate analog – to – digital conversion, allowing for precise measurement of process variables. Its conversion time of less than 3 ms per channel ensures real – time data acquisition, enabling the control system to respond promptly to changes in the process. This combination of high resolution and speed is crucial for applications that demand tight control and quick adjustments, such as chemical processing and power generation.
Wide Input Range and Flexibility
The module supports multiple analog input ranges, including the industry – standard 4 – 20 mA and 0 – 10 V signals. This flexibility allows it to interface with a diverse range of field devices, from pressure transmitters and flow meters to temperature sensors. Additionally, the 16 isolated channels provide the ability to connect multiple sensors simultaneously, reducing the need for additional hardware and simplifying system design.
Robust and Reliable Design
Designed for harsh industrial environments, the TRICONEX AI3351 can operate within a wide temperature range from -40°C to +70°C. The galvanic isolation between channels and system ground effectively protects against electrical interference, ensuring reliable signal transmission. The module also features built – in self – diagnostics that continuously monitor its internal components, enabling early detection of potential faults and minimizing downtime.
Ease of Integration
The AI3351 is seamlessly integrated with TRICONEX’s Tricon controllers through a proprietary communication protocol. This integration simplifies system configuration and maintenance, as the module can be easily added or removed from the control system without complex rewiring or reprogramming. The standardized interface ensures compatibility with other TRICONEX products, facilitating the expansion and upgrade of industrial automation systems.
