CX5120-0125

CX5120-0125 is a Beckhoff embedded PC in the CX Embedded PC Systems series. It uses a single-core Intel Atom E3815 processor operating at 1.46 GHz to execute control and processing tasks. The system includes 2 GB of DDR3 RAM for active program data. One CFast slot and one MicroSD slot provide options for system and application storage.

Two RJ45 LAN ports support 10/100/1000 Mbit/s Ethernet connections for network and automation communications. Four USB 2.0 ports, each rated at 500 mA, connect compatible peripherals. The integrated uninterruptible power supply provides one second of backup time for controlled data retention during a power interruption, while a 1 MB data buffer on the CFast storage preserves UPS-backed data.

The unit operates from a 24 V DC power supply and has a maximum power consumption of 11 W. Its dielectric strength is 500 V, providing electrical insulation between relevant circuits up to that test voltage. The IP20 protection rating guards against contact with internal components and solid objects larger than 12.5 mm, but it does not provide water protection.
