The V2426A Series embedded computers are based on the Intel 3rd genration processor, and feature 4 RS-232/422/485 serial ports, dual LAN ports, 3 USB 2.0 hosts, and provide dual DVI-I outputs. In addition, V2426A Series computers comply with a portion of EN 50155 specifications, covering operating temperature, power input voltage, surge, ESD, and vibration, making them suitable for a variety of industrial applications.
The dual Megabit/Gigabit Ethernet ports with M12 X-coded connectors offer a reliable solution for network redundancy, promising continuous operation for data communication and management. As an added convenience, the V2426A computers have 6 DIs and 2 DOs for connecting digital input/output devices. In addition, the CFast socket, SATA connector, and USB sockets provide the V2426A computers with the reliability needed for industrial applications that require data buffering and storage expansion. Moreover, the V2426A computers come with 2 peripheral expansion slots for inserting different communication modules (2-port CAN module, or HSDPA, GPS, or WLAN module), an 8+8-port digital input/output module, and a 2-port serial module, giving greater flexibility for setting up different industrial applications at field sites.
Pre-installed with Linux Debian 7 or Windows Embedded Standard 7, the V2426A Series provides programmers with a friendly environment for developing sophisticated, bug-free application software at a low cost. Wide temperature models of the V2426A Series that operate reliably in a -40 to 70°C operating temperature range are also available, offering an optimal solution for applications subjected to harsh environments.
