Product Description:
The CX5140-0155 is an embedded PC manufactured by Beckhoff within the CX Embedded PC Systems series. Designed for DIN-rail mounting next to EtherCAT I/O terminals, the unit acts as the central controller in automated machines by combining PLC logic, motion control, and SCADA communication on a single industrial platform. It integrates an x86 CPU, an internal uninterruptible power supply, and multiple fieldbus interfaces inside a fanless aluminum enclosure. This configuration is suitable for distributed cabinet installations where conventional rack-mounted PCs are impractical.
An Intel Atom E3845 processor operating at 1.91 GHz executes real-time tasks, while an internal chipset drives graphics at 542 MHz and shares 256 MB of video memory with system RAM. The quad-core architecture is supported by 4 GB of DDR3 RAM, helping maintain consistent cycle times when visualization or database services are active. Two independent Gigabit Ethernet controllers provide two RJ45 ports supporting 10/100/1000 Mbit/s, allowing one network to serve motion buses and the other to connect to enterprise networks without gateways. Cabinet heat load is limited because maximum power consumption is only 16 W. The required control voltage of 24 V DC can be supplied directly by a standard industrial power supply. The compact enclosure measures 142 × 100 × 92 mm, permitting side-by-side mounting with terminal blocks and power supplies.
The processor has four CPU cores, leaving processing capacity available for protocol stacks, communication tasks, and diagnostic services. A one-second integrated uninterruptible power supply writes process data to CFast or MicroSD storage during brief voltage interruptions. External peripherals, such as barcode scanners or removable storage devices, can connect through four USB 2.0 ports, with each port supplying up to 500 mA. This arrangement supports several low-power accessories without requiring a separate USB hub. Electrical isolation is enhanced by a dielectric strength of 500 V between the power supply and housing, supporting operation in control cabinets that also contain electrically noisy motor circuits.
