MOXA UC-4454A-T-5G Introduction
The UC-4400A computing platform is designed for embedded data-acquisition applications. The computer comes with up to four RS-232/422/485 serial ports, dual 10/100/1000 Mbps Ethernet ports, and up to 2 CAN ports, as well as a Mini PCIe and M.2 E socket to support LTE Cat. 4 and Wi-Fi 6E modules. These versatile capabilities let users efficiently adapt the UC-4400A to a variety of complex communications solutions. The UC-4400A is built around an ARM Cortex-A53 quad-core processor that has been optimized for use in energy monitoring systems, but is widely applicable to a variety of industrial solutions. With flexible interfacing options, this tiny, embedded computer is a reliable and secure gateway for data acquisition and data processing at field sites as well as a useful communications platform for many other large-scale deployments. Wide temperature cellular-enabled models are available for extended-temperature applications. All units are thoroughly tested in a testing chamber, guaranteeing that the cellular-enabled computing platforms are suitable for wide-temperature applications.
