Overview：
Invensys Triconex AI3351 Analog Input Module
Invensys Triconex AI3351 is a three-channel analog input module responsible for processing variable voltage signals from field sensors. The module converts variable voltage signals from the field into digital values. Featuring a triple-redundant architecture and a median selection algorithm, each channel's scan/conversion time depends on the configuration. The module provides 14-bit resolution and supports replacement while the system remains powered.

Function & Features：
- Three Independent Input Channels: The AI3351 module contains three fully independent input channels, with each channel processing voltage signals from the field separately.
- Median Selection Algorithm: The three channels convert voltage signals into digital values and transmit the data to three main processors. The system determines a correct value using a median selection algorithm.
- Precise Fault Indication: Fault indicator lights on the AI3351 module clearly identify the specific channel with a fault, rather than indicating failure of the entire module.
