The DA-660 embedded computers come with 8 or 16 softwareselectable RS-232/422/485 serial ports, making them suitable for a variety of industrial applications. Two 10/100 Mbps Ethernet ports are included for network redundancy. In addition, the DA-660 computers are designed with a standard 19-inch, rugged 1U rackmount case, and are embedded with a 100-240V AC/DC power input. This combination of features gives users a robust and reliable ready-to-run solution for applications such as data acquisition and power substations.
