Product Description:

The CX5140-0170 is an embedded PC manufactured by Beckhoff within the CX Embedded PC Systems series. Designed for DIN-rail installation beside fieldbus terminals, it functions as the central controller in industrial automation cells, executing motion sequences, machine logic, and on-site visualization without the footprint of a panel PC. The device combines a CPU board, persistent storage, and integrated communication interfaces in one housing, enabling scalable control architectures for small stand-alone stations and distributed production lines.

Processing capability is supplied by an Intel Atom E3845 1.91 GHz chip with 4 physical cores, so separate PLC tasks, Windows services, and OPC UA servers can run concurrently without affecting deterministic cycle times. Working data and the operating system reside in 4 GB of DDR3 RAM. The integrated graphics engine allocates 256 MB of that memory and drives a DVI-I connector at up to 1920 × 1200 pixels, supporting high-resolution operator panels. Network traffic is handled through 2 × RJ45 Gigabit ports that allow one connection to field devices and a second connection to supervisory networks. Under normal load, the controller draws only 16 W, which eases power budgeting and thermal management inside compact cabinets.

The housing measures 142 × 100 × 92 mm, allowing the PC to share terminal space on a standard control rail. A 24 V DC input feeds the internal power supply and can be connected in parallel with an external UPS. When a UPS is fitted, power consumption rises to 23 W, and 1 MB of dedicated nonvolatile RAM secures process data during transfer to flash memory. CFast and microSD slots provide two mass-storage options for operating system images, recipe files, and log archives. Four USB 2.0 ports connect service tools, barcode scanners, or wireless adapters. The unit weighs 1,095 g, which keeps mechanical stress low on vertical rails during vibration.
