The CX5240 is an Embedded PC based on the Intel AtomВ® x5-E3940 processors with a clock speed of 1.6В GHz (quad-core) and 8В GB DDR4-RAM. The basic equipment includes two independent, Gigabit-capable Ethernet interfaces as well as four USBВ 3.0 and one DVI-D interface. A wide range of additional connection options or gateway functions are available thanks to the optional interface and I/O level, which can consist of either E-bus or K-bus terminals and can be fitted ex factory. In addition, a system module or fieldbus module from the CX2000 series can be plugged in via the high-pole connection on the left-hand side of the device. Although the total number of plug-in modules of the type CX2500-xx is limited to one with the CX5200 series, it is possible in this way, for example, to implement two further Gigabit-Ethernet interfaces or four further USB interfaces or a further fieldbus interface. Furthermore, the CX5240 is characterized by an internally electrically isolated power supply unit, built-in 1s-UPS, low power consumption and fanless cooling.
