CX5120 | Embedded PC with Intel® Atom™ processor


The CX5120 has an Intel® Atom™ single-core processor with a clock rate of 1.46 GHz. The hardware interfaces in this new series are oriented and implemented identically to those of the existing CX5000 series. Two independent, Gigabit-capable Ethernet interfaces, as well as four USB 2.0 and a DVI-I interface are available. A multitude of further connection options or gateway functions are created by an option interface, which can be pre-fitted in the factory, as well as the I/O level, which can selectively consist either of E-Bus or K-Bus terminals.

The CX5120 is characterised by low power consumption and a fanless design.


Depending on the installed TwinCAT runtime environment, the CX5120 can be used for implementing PLC or PLC/Motion Control projects with or without visualisation. The execution of Motion Control applications with interpolating axis movements is also possible.

The extended operating temperature range from -25 to +60 °C enables the use in climatically demanding environments.

Like the CX5000, the CX5100 series has a compact design; a modular device with extension modules like in the CX2000 series is not available.

The order identifier is derived as follows:
