“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, maximizing productivity in IIoT applications” Ryan Teng, Head of Industrial Wireless and Arm-based Computer Divisions.

High-speed Wireless and Network Troubleshooting Maximizes Productivity

The UC-4400A Series, Moxa's first 5G Arm-based computers with ultra-low latency, high connection-interface density, and enhanced 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 reduce interference, enabling faster data transmission. In addition, Moxa’s partnership with Qualcomm for Qualcomm Extended Diagnostics Monitor (QXDM) provides advanced log analysis and troubleshooting support to further enhance the quality of wireless connections.

Enhanced Reliability and Performance With Dual Wireless Connectivity

The UC-3400A and UC-4400A Series offer the advantage of dual wireless connectivity, integrating both 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 provides seamless failover between cellular and Wi-Fi, enhancing system reliability. This makes the computers ideal for critical industrial applications that require uninterrupted data transmission. Additionally, load balancing can be used to optimize data traffic across both connections, further maximizing network performance and efficiency.

Global Certification and Industrial-grade Product Design Ensure Reliable Operations

The UC-3400A and UC-4400A Series have been tested and certified globally for UL, FCC, CE, and RCM, as well as by North American carriers PTCRB, AT&T, and Verizon (expected to be certified in Q1 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 ensure seamless and secure data transmission in diverse industrial environments and regions.

Designed for harsh conditions, the UC-3400A and UC-4400A computers can operate in the -40 to 70°C 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 5-year product warranty and 10-year OS support, these products are built for long-term reliability.

IEC 62443-4-2 Security Level 2 Compliance Secures Assets and Saves Time

Moxa’s 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 at least six 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 authorized 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, preventing unauthorized access to the system.
