Product Description:
The CX5140-0135 embedded PC is produced by Beckhoff within the CX Embedded PC Systems series. Intended for cabinet-mounted industrial automation, this unit consolidates PC-based control, fieldbus communication, and HMI tasks in one DIN-rail package. By running the TwinCAT runtime environment, it executes PLC logic, coordinated motion, and operator visualization directly on the controller, making it the central node for packaging machines, HVAC plants, and material-handling lines that demand deterministic cycle times.
It is powered by an Intel Atom E3845 processor operating at 1.91 GHz. The 4-core architecture lets the real-time scheduler allocate separate threads to logic, motion, and communication without context-switch delays. Memory resources include 4 GB DDR3 RAM, so medium-sized PLC projects and web-based HMIs can reside completely in volatile storage. Even during full CPU utilization, the controller draws only 16 W, enabling passive heat dissipation through the aluminum housing without requiring fans. Application code and archived data are stored on a CFast card or microSD module, and the electronics fit within a 142 × 100 × 92 mm enclosure that mounts beside standard CX power supply terminals.
For external interfaces, the platform furnishes 2 × RJ45 10/100/1000 Mbit/s Ethernet ports for separated control and diagnostics networks, while service devices can be attached through 4 × USB 2.0 sockets. The electronics are fed with 24 V DC supplied by the adjacent CX power module, and an integrated one-second UPS retains 1 MB of process data during brief mains interruptions. Cabinet installation is simplified by the enclosure’s IP20 rating, permitting operation in clean switchgear without additional sealing. TwinCAT 3 Runtime (XAR) comes preloaded so that function licenses can be added later to suit motion, safety, or measurement tasks.
