Overview

The IA3341 is based on the MOXA ART ARM9 industrial processor, and features 2 RS-232/422/485 serial ports,

dual LANs, 4 digital input channels, and 4 digital output channels. In addition, the IA3341 computer has 2

analog input channels and 2 thermocouple channels, making it the ideal solution for a variety of industrial

applications.

By supporting multiple interfaces, the IA3341 can connect to different types of devices, making it particularly

well-suited for solar power applications. Meters, sensors, and other devices can all connect easily to the IA3341,

and with its powerful computing platform, the IA3341 can be used as a front-end controller to perform

industrial tasks, such as data acquisition, data computing, protocol conversion, and data analysis.

The industrial-grade design of the IA3341 provides a robust, reliable computer that can fit any industrial

environment, and the open source Linux platform gives programmers a convenient tool for developing

sophisticated, bug-free application software at a lower cost.

In addition, the built-in Modbus TCP library and web server help users easily monitor and retrieve the AI data,

which is particularly useful for applications, such as solar power and environmental monitoring.
