The IA240 embedded computers are designed for industrial automation applications. The computers feature 4 RS-232/422/485 serial ports, dual LANs, 4 digital input channels, 4 digital output channels, and a PCMCIA cardbus and SD socket in a compact, IP30- protected, industrial-strength rugged housing.
The IA240’s vertical DIN-rail form factor makes it easy to install the computers in a small cabinet. This space-saving solution also facilitates easy wiring, making the IA240 a great choice as front-end embedded controllers for industrial applications.
Wide-temperature models of the IA240 are also available. The IA240-T can operate reliably in a temperature range from -40 to 75°C, making them appropriate for harsh industrial automation environments.
The industrial design of the IA240 provides a robust, reliable computing platform. Due to their RISC-based architecture, the IA240 computers will not generate a lot of heat, making them ideal for industrial automation environments.

White Paper
Building a Future-Proof Data Processing Solution with Intelligent IoT Gateways

To date, most discussions about the Industrial Internet of Things (IoT) have been about connecting new devices and rapidly bringing them online. In this white paper we look at the implications of bringing such a large number of devices online, namely, the need for efficient methods to collect information from these devices, and discuss how to handle the large amount of data collected from these devices.
Industrial IoT solutions are judged on their ability to adapt to various data acquisition needs and how they can transform the data collected from devices into useful business insights that can help decision makers. What makes an Industrial IoT solution truly stand out is the flexible data handling possibilities that it can provide…

White Paper
Developing a Data Acquisition Platform for Industrial IoT Applications

The impact the Internet has had on the way humans live their lives has been unprecedented. It has allowed us to communicate and interact with each other in ways previously unimaginable. Recently, it has opened the door for what many are describing as something that will become more important to our everyday lives than the Internet, the Internet of Things (IoT). One of the most exciting possibilities is in industrial applications, more commonly referred to as the Industrial Internet of Things (Industrial IoT), where communication and interaction capabilities can be extended to devices or things used for factory automation, renewable energy applications, smart grids, intelligent transportation systems, and even oil and gas applications..

Application Notes
Accelerate your IIoT-Ready Applications with Smart Industrial Computing

Data is at the heart of the Internet of things (IoT). To make critical data-informed decisions, businesses first need to capture and collect data from all sorts of devices over the Internet before converting the data into valuable business information. Moxa has applied its rich experience in the industrial automation field to provide industrial computing solutions that integrate data acquisition and device management for large-scale, Industrial IoT applications. In this brochure, we will examine several typical applications to see how Moxa’s solutions can help businesses conquer the challenges in the Industrial IoT environments…..
