DIN-Rail Computers

RISC-based embedded computer with 2 serial ports, 4 DIs, 4 DOs, 2 AIs,

2 thermocouples, dual LANs, SD, Linux

The IA3341, which is designed for solar power and environmental

monitoring applications, 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.

As an added plus, the IA3341 offers a Modbus TCP client library in C

for Windows programmers. The library helps users to easily acquire AI

and thermocouple data. This feature can efficiently accelerate remote

device monitoring and data acquisition at a lower cost.
