CX2040-0100-1002 by Beckhoff

The CX2040-0100-1002 is an industrial PC module produced by Beckhoff and supplied within the CX Embedded PC Systems series. It acts as the central control node in distributed automation architectures, hosting real-time task scheduling, fieldbus communication, and visualization services directly on the DIN rail alongside I/O terminals. By combining an Intel Core i7-2715QE processor with integrated interfaces, the device eliminates the need for a separate rack-mounted computer and reduces panel space in machine and process control cabinets.

The quad-core architecture provides 4 processor cores that share a base clock of 2.1 GHz, so PLC, HMI, and motion applications can run concurrently. A main memory pool of 4 GB DDR3 RAM holds executable code and variable tables, while a nonvolatile NOVRAM segment preserves retentive data during power loss. Peak power consumption is limited to 32 W, allowing passive ventilation in tight enclosures when the unit is supplied by a control circuit rated at 24 V DC. Two independent Gigabit controllers provide 2 Ethernet channels for time-critical fieldbus protocols or separation of plant networks. Graphics output uses 128 MB of dedicated video memory for panel displays. The unit is supplied without a preinstalled operating system, allowing users to install an appropriate real-time Windows or TwinCAT/BSD image.

Peripheral access is provided through 4 USB 2.0 connectors that support mass-storage devices, service tools, or local HMI touchscreens. The housing meets the IP20 protection class, so it is suited for clean electrical cabinets where protection against finger contact is required but additional sealing is unnecessary. Internal circuitry withstands up to 500 V of dielectric strength between the supply and protective earth, enhancing safety in systems with multiple ground references. The housing measures 99 mm in height, 144 mm in width, and 91 mm in depth, keeping the profile compact for multi-axis machines or skid-mounted process units.
