Product Description:

The CX2040-0112 belongs to the CX Embedded PC Systems series produced by Beckhoff. This compact controller functions as the central CPU in an automation cell, executing PLC logic, coordinated motion tasks, and visualization created in the TwinCAT 2 NC-PTP Runtime environment. By integrating deterministic control software with fieldbus couplers and local I/O terminals, the unit can replace separate PLCs, motion cards, and industrial PCs while maintaining the real-time performance required on factory floors.

The hardware platform is driven by an Intel Core i7-2715QE processor that runs at 2.1 GHz and offers 4 CPU cores for parallel task execution across control, communication, and interface duties. System data reside in 4 GB DDR3-RAM, while HMI graphics share 128 MB Shared Memory with the GPU, which avoids the need for a discrete video card. A minimum 20 GB CFast module stores the operating system, recipes, and historical logs, and 128 kB of NOVRAM retains non-volatile process variables during power loss. For local expansion, the K-bus backplane moves 2048 bytes of input and 2048 bytes of output data per cycle to digital and analog terminals. Four USB 2.0 Type A ports, each rated at 500 mA, allow connection of service tools, barcode readers, or external drives.

Power is supplied through a 24 V DC (-15% / +20%) source, and overall consumption stays below 32 W, allowing fanless cabinet installation. Two gigabit adapters provide networking via 2 × RJ45 10/100/1000 MBit/s links for EtherCAT, OPC UA, or separation of machine traffic from the plant network. Galvanic spacing withstands 500 V dielectric strength between supply and signal circuits, supporting industrial insulation practices. The aluminum housing measures 144 × 99 × 91 mm, conserving panel depth while still accommodating passive convection paths. This compact layout supports dense cabinet arrangements without requiring active cooling hardware.
