Advantech Launches Explosion-Proof Data Gateways with C1D2 Certification for Harsh Industrial Environments


November 2021, Taipei, Taiwan - Advantech, a leading provider of embedded computing solutions, is pleased to announce its new explosion-proof data gateways, UNO-410 and UNO-430 EXP.  Powered by an Intel® Atom® E39XX processor with 8 GB of DDR3L memory, both gateways feature an optimized form factor to ensure easy deployment and maintenance in diverse environments. For in-cabinet installations, the ultra-compact UNO-410 gateway supports DIN-rail mounting; whereas for cabinet-free installations, the UNO-430 EXP gateway features an enclosure with an easy-access front door that allows convenient maintenance. Aimed at industrial applications in harsh environments, UNO-410 and UNO-430 EXP are UL C1D2, ATEX, and IECEx certified for explosion tolerance, making them ideal for a wide range of applications in the oil & gas, mining, food & beverage, and chemical & pharmaceuticals industries.

Rugged Design with Explosion-Proof Certification

Designed to withstand industrial applications, the explosion-proof UNO gateways feature a rugged design and certification for safe operation in hazardous environments, including in-cabinet and outdoor environments. Specifically, UNO-410 is certified for operation in UL Class I, Division 2, ATEX/IECEx Zone 2-classified locations, i.e., explosion-proof enclosures. Meanwhile, the UNO-430-E1H standalone gateway is certified for UL Class I, Division 2, ATEX/IECEx Zone 2, Zone 22-classified environments, making it ideal for outdoor/roadside installations.

IECEx/ATEX Explosion Proof Rating for UNO Gateways

UNO-410 is also equipped with a cable locking mechanism for securing USB cable connections to prevent data losses and fire. The COM and digital I/O ports with 2500 VDC isolation protection eliminate noise between devices, thereby enhancing the overall system stability. Regarding the UNO-430 EXP gateway, the industrial-grade design supports a wide operating temperature range (-40 ~ 70 °C/-40 ~ 158 °F) and is IP66 rated for protection from water and dust, ensuring optimal operation under extreme conditions. The ATEX-certified cable gland protects electrical components by sealing the outer cable sheath and excluding dust and moisture from the enclosure. Moreover, the provision of a cable gland also supports the installation of a ½-inch NPT metal conduit (for U.S.) or poly-filled cable (for E.U.) for greater ease-of-installation and deployment flexibility.

Scalable Wireless Communication for Remote Management

With the provision of dual expansion slots for wireless and LTE modules, the explosion-proof UNO gateways support scalable wireless communication for remote monitoring, data transfers, and mobile operation. UNO-410 features an mPCIe slot for integrating a Wi-Fi module and a M.2 3042 (B key) socket for an LTE module, while UNO-430 EXP features M.2 (E and B key) sockets to enable the provision of Wi-Fi, 5G/LTE, and GPS capabilities. With UNO gateways, extensive wiring is no longer required, making them ideal for industries with large-scale factories and outdoor equipment.

Easy Installation and Maintenance in Diverse Environments

To withstand the most demanding applications, UNO-410 and UNO-430-E1H gateways are designed for rapid installation, flexible deployment, and reliable operation in hazardous environments. UNO-410 is equipped with an optimized DIN-rail kit with a new sliding hook design and user-friendly release latch, enabling easy installation in environments with limited space. By contrast, UNO-430 EXP features an enclosure with front door to provide easy deployment, access, and operation. UNO-430 EXP also supports dual-direction mount options (wall and pole mount) to ensure flexible deployment in diverse industrial environments.
