The Industrial Automation Group of Advantech announces that its Serial Device Servers (EKI-1351, 1352, 1521, 1522, and 1524) and Modbus Gateways (EKI-1221, 1222, and 1224) have received Underwriters Laboratories (UL) Class 1, Division 2 (groups A, B, C, and D) certification for use in hazardous locations.

Installation of electronic devices in environments where flammable liquids, gasses and vapors may be present is a real challenge. It is critical to use the right equipment in these locations. With UL Class I, Division 2 certification, the EKI-1000 series of products are now UL/cUL approved for use in these types of hazardous environments, which are common to oil and gas, mining, and chemical processing industries.

The EKI-1220 series of Modbus Gateways enables quick and easy integration of Modbus ASCII and RTU devices with Industrial Ethernet networks and Modbus/TCP enabled devices. Supported configurations include: Ethernet master to serial slave, serial slave to Ethernet master, and concurrent operation of both modes.

The EKI-1300/1500 series Device Servers are a drop-in solution to add network connectivity to non-networked devices and equipment. With a wired Ethernet or 802.11b/g wireless connection, and one or more RS-232/422/485 serial ports, Device Servers encapsulate serial data for transport over Internet Protocol (IP) networks. Used separately or together with a host computer or PC, Device Servers are an ideal solution to integrate serial devices with Ethernet and IP networks, and to overcome the inherent distance limitations and point-to-point nature of serial devices.

The EKI-1000 models are packaged in a compact and thin metal DIN-rail mount chassis, and are ruggedized for demanding industrial applications. They include dual 12 to 48 V_DC power inputs, power line surge (EFT) protection of 3,000 V_DC, and 4,000 V_DC Ethernet ESD protection to ensure maximum system uptime and uninterrupted communications

Advantech continues to expand the capabilities and breadth of their line of industrial Ethernet products. With these new certifications, the compact and rugged EKI-1000 series of Device Server and Modbus Gateways can now be used in a much broader range of applications, including use in hazardous locations.
