Product Description:
The CX5120-0120 is an embedded PC module manufactured by Beckhoff for the CX Embedded PC Systems series. Intended as a compact control platform, the unit merges processor, memory, fieldbus interfaces, and optional I/O expansion into a DIN-rail package that replaces conventional PLC hardware. Within an automation cell, it can execute motion control, data logging, and visualization tasks while connecting directly to remote terminals and drives. This layout helps consolidate control functions in one housing without requiring a separate industrial computer and PLC assembly.
Its single Intel Atom E3815 core operates at 1.46 GHz, delivering deterministic cycle times for soft-PLC workloads. The processor is paired with 2 GB DDR3-RAM, giving enough volatile space for user programs, variables, and buffering of field data. Because the device is supplied by 24 V DC, it can share the same low-voltage rail as sensors and actuators, and it draws a maximum of 11 W, which helps limit heat inside the control cabinet. The housing measures 122 x 100 x 92 mm, so multiple controllers can mount side by side on limited rail length. An IP20 rating indicates finger-safe ingress protection inside enclosures. TwinCAT is not installed at the factory, so the required runtime version can be loaded later to match the application.
A dielectric strength of 500 V separates the 24 V logic domain from exposed I/O, supporting insulation checks during panel verification. The integrated UPS bridges supply interruptions for 1 s, giving the operating system time to flush buffers before an orderly shutdown. That short ride-through interval can help reduce the risk of incomplete data writes during brief power loss. The single-core architecture also works with a 400 MHz graphics base clock to drive an Intel HD Graphics engine that uses 256 MB of shared memory, allowing local visualization without a separate graphics card.
