Overview

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 3rd Gen Intel®
Core™ Celeron 1047UE 1.4 GHz CPU and HM65 chipset, which supports
standard x86, 1 x VGA, 4 x USB, 6 Gigabit LAN ports, 2 RS/232/422/485
3-in-1 serial ports, and 10 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 the CTOS process.

Another plus is that the serial ports come with 2 kV digital galvanic
isolation protection to guarantee commu nication 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 power substation automat io n
applications.
