The UA-5231 is a data acquisition controller and communication server for Industrial Internet of Things (IIoT) applications. The UA-5231's built-in OPC UA Server and MQTT Client Service support a variety of common industrial communication protocols. Its RISC-based CPU architecture has the advantages of small size low power consumption that lets this series can be placed in a small space to fit variety of rooms, equipment and case environment. In the hardware, it provides a variety of communication interfaces, such as Gigabit Ethernet, USB, RS-232 and RS-485 ports to connect diverse devices. It runs on a Linux operating system (Kernel 3.2.14).

Applying OPC UA can integrate the I/O products of ICP DAS with the third-party devices, import the data information to the SCADA, database or decision-making systems for the back-end management, and satisfy the reliability, interoperability and security needs of the industrial automation system. Using MQTT communication can bridge the system with the Internet of Things (IoT) to meet the current trend of the smart internet.

  • OPC UA Server and MQTT Client Service
  • MQTT Broker Inside: Compliance with MQTT v3.1.1 protocol. Users don't need to build Broker system by themselves.
  • PID Logic Operation dynamically combines remote I/O devices for the PID logic control to provide temperature control and case field solutions.
  • Supports Modbus TCP/RTU Master via RS-485, RS-232 and Ethernet ports
  • Supports MQTT protocol to allow IoT devices communicate with OPC UA system and convert and publish the devices' data under the UA-5231 server to the IoT system.
  • Web-based User Interface for Easy Configuration
  • AM3352, 720 MHz
  • 512 MB RAM and 256 MB Flash
