DA-681A - Intel Celeron 1047UE 1.4GHz 19" 1U Rack-mount Substation PC with six Ethernet ports, twelve COM ports and IEC 61850-3, IEC 60255 and IEEE 1613 compliance
CE is a mandatory standard for products on the market in the European Economic Area. By CE marking a product, the manufacturer ensures that the item meets the essential safety requirements set out in the applicable CE directive.
This product fully adheres to the Restriction of Hazardous Substances Directive 2002/95/EC, RoHS for short.  The directive covers the restriction of use of certain hazardous substances in electrical and electronic equipment and was adopted in February 2003 by the European Union.
Underwriters Laboratories (UL) is an independent product safety certification organisation based in the United States. UL develops standards for products, materials, components, assemblies, tool and equipment, mainly dealing with product safety.
These products use heatsink, heatpipe and extrusion technology to dissipate the heat generated by the system rather than using traditional fans thus improving system reliability and longevity.
IEEE 1613 Environmental and testing requirements for communications networking devices in electric power substations.
These devices and systems have been designed to accept a wide voltage DC power input. This feature is desirable in the industrial market where a fixed voltage level or mains AC power cannot be guaranteed.
The Federal Communications Commission (FCC) is an independent agency of the United States government that sets standards and governs the testing of conducted and radiated emissions such as EMI.
These products utilise high quality industrial grade components enabling them to work in extended wide temperature environments. They are capable of running below -20C and above +70C and offer further protection than standard wide temperature rated products.
These products come with a standard three year manufacturer warranty.
IEC 61850-3 communication standard for electrical substation automation systems in the Power and Energy market.

The Moxa DA-681A Series x86-based rack-mount embedded computers are designed for control, monitoring, data acquisition, and protocol conversion applications. With its robust design, the DA-681A is suitable for industrial automation applications, such as power automation, transportation, and oil and gas.

The DA-681A’s main operating system is based on the Intel Celeron 1047UE 1.4GHz CPU and HM65 chipset, which supports standard x86, one VGA, four USB, six Gigabit LAN ports, two RS/232/422/485 3-in-1 serial ports, and ten RS-485 (RS-422 by CV) ports.

The DA-681A has a mini PCIe socket for mSATA and comes with Linux pre-installed; Windows 7 Embedded is also supported by Impulse.

Another key feature of the DA-681A is that the serial ports come with 2kV digital galvanic isolation protection to guarantee communication reliability in harsh industrial environments. In addition, the state-of-art IEC 61850-3, IEEE 1613, and IEC 60255 compliance all-in-one design provides rich interfaces especially well suited for of power substation automation applications.
