  • Meets the EN 61000-6-2 and EN 61000-6-4 standards for
    industrial EMC applications  
  • Ready-to-run Debian 9 with 10-year long-term support*
  • Supports Linux real-time OS mode
  • Robust Root File System to prevent the system from being bricked due to a firmware update failure



Moxa’s UC-3100 Series industrial computers can be used as edge-field smart gateways for data pre-processing and transmission, as well as for other embedded data acquisition applications. The UC-3100 Series includes three models, each supporting different wireless options and protocols.


The UC-3100’s advanced heat dissipation design makes it suitable for use in temperatures ranging from -40 to 70°C. In fact, the Wi-Fi and LTE connections can be used simultaneously in both cold and hot environments, allowing you to maximize your data pre-processing and data transmission capability in most harsh environments.

In addition, TPM v2.0 uses a hardware chip to boost data security, making it highly unlikely that hackers will be able to steal your data, either remotely or locally.


The UC-3100 is more than just a hardware solution. In order to offer a better user experience with a Moxa RISC computer, the UC-3100 supports the following software features, allowing you to use the most suitable configuration based on your particular application.
• High VPN Performance: greater than 70 Mbps with AES-256 encryption Ethernet throughput
• Robust file system to prevent the system from being bricked due to a firmware upgrade interruption
• Cybersecurity auto-config system compliant with IEC 62443 lv.2
• Real COM mode to provide a control interface with Moxa’s NPort products


In addition, Moxa provides 10 years of Linux OS support* from Moxa’s customer support engineers. With a new version of the Debian repository released on average every 2 to 3 years, long-term Linux OS support helps you create a reliable solution that will be supported now and long into the future.

White Paper

Five Reasons Why Your IoT Application Needs Fog Computing


Fog Computing White PaperIndustry experts have warned that the cloud-computing models deployed in many IoT systems today are ill equipped to deal with the volume of data generated by the billions of IoT devices that are slated to go online in the next couple of years. To add to this, these devices generate data in a multitude of formats using a variety of protocols, making their acquisition and realtime processing difficult. In this white paper, we look at the fog computing model and why it is required in today’s IoT application...more



White Paper

How to Choose a Good Computing Platform for Your IIoT


The market today is flooded with embedded solutions for the Industrial IoT. You can now choose from a wide variety of RISC-based embedded computers, single-board computers, and development boards to implement your IIoT solutions. With single-board computers such as Raspberry Pi available for for as low as US$ 40 per board, is it a good strategy to cast your loT with these development boards? What are some of the key factors that you must consider when choosing an embedded computing solution for your industrial applications?... more

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.... more
