Product Description:

The CX5140-0123/000048740 is an embedded PC manufactured by Beckhoff for the CX Embedded PC Systems series. It serves as the main PLC and motion controller in distributed installations and runs TwinCAT 2 NC I Runtime directly on its motherboard, so a separate rack computer is not required. This arrangement keeps control functions close to the machine I/O and reduces the amount of separate hardware in the cabinet. By combining real-time control, diagnostics, and HMI processing in one housing, the unit helps simplify cabinet layouts in packaging machines, conveyor cells, and energy management panels.

Computation is handled by an Intel Atom E3845, 1.91 GHz processor that uses 4 cores for control and visualization tasks. The CPU is paired with 4 GB DDR3 RAM, which gives the runtime environment space for logic, kinematics tables, and visualization buffers. A regulated input of 24 V DC (-15% / +20%) feeds the board-level power circuit, and total demand stays below 16 W, which helps support passive cabinet cooling. The aluminum housing measures 142 × 100 × 92 mm and weighs 1.095 kg, making DIN-rail mounting practical next to I/O terminals. Internal CFast and microSD slots store the operating system image along with recipe or event files, and a one-second integrated UPS preserves 1 MB of RAM so critical variables can survive brief power dropouts.

A DVI-I output drives external panels at up to 1920 × 1200 for local status screens and operator displays. Four front-mounted ports provide 4 × USB 2.0, 500 mA each for service media, cameras, or barcode readers, while dual Gigabit Ethernet controllers expose 2 × RJ45, 10/100/1000 Mbit/s for fieldbus couplers and SCADA backhaul. The CPU segment can also supply 10 W at 5 V to E-bus or K-bus terminals, which supports attached I/O without a separate feed for that stack. The enclosure carries an IP20 rating for indoor switchgear locations where direct liquid contact is not expected.
