Moxa’s new 64-bit arm computers With 5G / LTE / Wi-Fi 6 connectivity deliver trusted IIoT solutions
Moxa Europe GmbH, a leader in industrial communications and networking, has announced the launch of its next-generation 64-bit Arm-based computers UC-3400A and UC-4400A Series featuring industry-leading dual-wireless, 5G/LTE and Wi-Fi 6, connectivity. Built around an Arm Cortex-A53 quad-core processor and featuring dual-wireless connectivity, these computers are strictly tested to ensure reliable RF performance and deliver exceptional performance in industrial IoT applications. With the rapid expansion of wireless
connectivity in industrial environments, businesses are increasingly integrating 5G, LTE, and Wi-Fi 6 technologies to enhance operational efficiency and real-time data exchange. However, the growing number
computers, designed with a quad-core processor, reliable dual-wireless connectivity, simplified system soſtware for easy development, IEC 62443-4-2 SL2 compliance, and a 10-year OS maintenance plan, including security patches and fixes. Tese computers deliver high performance with optimised energy efficiency, enabling customers to scale their IIoT applications reliably. “Moxa is continuously investing in
of wireless devices presents challenges in managing connectivity, ensuring security and optimising performance across different technologies. To address these challenges, Moxa unveils its new 64-bit Arm-based
wireless communication technology including Wi-Fi, Cellular and 5G, to ensure reliable connectivity to the cloud for edge-computing devices, even in harsh industrial environments. Dual wireless connectivity ensures uninterrupted data transmission, maximising productivity in IIoT applications” Ryan Teng, Head of Industrial Wireless and Arm-based Computer Segment.
Vaisala lowers transformer risks with enhanced monitoring technology
As demand grows for continuous transformer monitoring, Vaisala has released a new enhanced version of its Optimus OPT100 DGA monitor by adding oxygen and nitrogen parametres. The Optimus is designed to reduce
the possibility of unplanned outages and help prevent catastrophic transformer failures. A transformer’s lifetime is determined
by the condition of its solid insulation, which can be detrimentally affected by air leaks. The easiest and most robust way to reliably detect such leaks is to continuously measure the Total Gas Pressure (TGP) of all dissolved gases in the transformer’s oil, where oxygen and nitrogen are the dominating components. TGP therefore provides real-time detection, even in the very early

phases, of air leaks into a sealed power transformer’s tank. With the benefit of TGP, decision-makers in transformer maintenance learn whether the insulation system of a sealed transformer is exposed to air, which allows them to make informed decisions on actions such as oil degassing or sealing system repair. The real-time monitoring of fault gases by dissolved gas analysis (DGA) is a
well-known and established method for the early detection of quickly evolving faults. However, some processes develop slowly in transformers. Oxidation for example, can affect their operational life, usually taking years to show significant effects. Vaisala has therefore developed its DGA monitors to track the key parametres and thereby automate effective transformer condition assessment.
