Product Introduction
TRICONEX 3721 is an analog input module.Analog Input (AI) Modules includes three independent input channels. Each input channel receives variable voltage signals from each point, converts them to digital values, and transmits the values to the three Main Processor modules on demand. In TMR mode,one value is then selected using a midvalue selection algorithm to ensure correct data for every scan.

Product Details
TRICONEX 3721 features:
High resolution and accuracy: With 12-bit or 14-bit configurable resolution and less than 0.15% of full scale, it can accurately collect analog signals and meet industrial applications with high measurement accuracy requirements.
Multi-channel input: With 32 differential input channels, it can connect multiple sensors or signal sources at the same time to achieve synchronous acquisition and processing of multiple analog signals, which is suitable for large and complex industrial control systems.
Wide voltage input range: Supports 0-5V DC or - 5 to + 5V DC voltage input range, can adapt to sensors and devices with a variety of output voltage ranges, and enhances the versatility and flexibility of the module.
Fast update rate: The input update rate of 10ms can quickly collect and process analog signals, and promptly reflect the changes in field signals, which helps to achieve real-time monitoring and control of industrial processes.
High common mode rejection ratio: Up to -85dB common mode rejection ratio can effectively suppress common mode interference signals, ensuring accurate acquisition and transmission of analog signals in industrial environments with interference, improving signal stability and reliability.
Overvoltage protection function: With 150V DC/115V AC continuous input overvoltage protection, it can prevent overvoltage damage to the module caused by abnormal external signals or misoperation.
