New 64-bit Arm computers deliver trusted IIoT solutions

Moxa Europe GmbH has launched 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 offering dual-wireless connectivity, these computers are strictly tested to provide reliable RF performance and deliver exceptional performance in IIoT applications.

With the rapid expansion of wireless connectivity in industrial environments, businesses are increasingly incorporating 5G, LTE, and Wi-Fi 6 technologies to improve operational efficiency and real-time data exchange. However, the growing number of wireless devices presents challenges in managing connectivity, ensuring security, and optimising performance across different technologies.

To manage these challenges, the company unveils its new 64-bit Arm-based computers, created with a quad-core processor, reliable dual-wireless connectivity, simplified system software for easy development, IEC 62443-4-2 SL2 compliance, and a ten-year OS maintenance plan, including security patches and fixes. These computers provide high performance with optimised energy efficiency, allowing customers to scale their IIoT applications reliably.

"Moxa is continuously investing in 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," said Ryan Teng, head of Industrial Wireless and Arm-based Computer Segment.

The UC-4400A Series, the company's first 5G Arm-based computer with ultra-low latency, high connection-interface density, and improved reliability, empowers real-time data processing and connects the highest number of devices to industrial applications. Expansion modules for Wi-Fi 6E connectivity enhance the bandwidth and greatly decrease interference, enabling faster data transmission. In addition, its partnership with Qualcomm for Qualcomm Extended Diagnostics Monitor (QXDM) supplies advanced log analysis and troubleshooting support to enhance the quality of wireless connections further.

Both series provide the advantage of dual wireless connectivity, integrating cellular and Wi-Fi capabilities in a single computer. This combination ensures connection redundancy for maintaining continuous operations even when one connection is down. Moxa Connection Manager (MCM) utility supplies seamless failover between cellular and Wi-Fi, enhancing system reliability. This makes the computers excellent for critical industrial applications that need uninterrupted data transmission. Also, load balancing can optimise data traffic across both connections, further maximising network performance and efficiency.

The computer series have been tested and certified globally for UL, FCC, CE, and RCM by North American carriers PTCRB, AT&T, and Verizon (UC-4400A expected to be certified in Q2 2025). In addition, the UC-3400A Series has been tested for ATEX and CID2 requirements in hazardous environments and is expected to be certified in Q2 2025. These certifications provide seamless and secure data transmission in diverse industrial environments and regions.

Designed for harsh conditions, the computers can operate in the -40C to +70C temperature range with wireless capabilities. The computers are ideal for applications in the distributed energy resources, industrial automation, and oil and gas sectors. With a five-year product warranty and ten-year OS support, these products are constructed for long-term reliability.

The UC-3400A and UC-4400A Series computers with Moxa Industrial Linux (MIL3) and compliance with IEC 62443-4-2 Security Level 2 requirements can save users several months of development time on security features. The secure operating system includes Secure Boot, a built-in security mechanism that ensures edge computers boot only from validated and authorised bootloader and operating system. A Hardware Root of Trust, a hardware-based chain-of-trust validation sequence, safeguards the Secure Boot process and software updates, stopping unauthorised access to the system.
