Beckhoff CX5140-0175 Embedded PC

The Beckhoff CX5140-0175 is a high-performance Embedded PC engineered for demanding industrial control and motion applications. Powered by a 1.91 GHz Intel Atom® E3845 quad-core processor, this fanless, DIN rail-mounted controller delivers efficient multi-core performance in a compact form factor.

It features 4 GB DDR3 RAM, dual Gigabit Ethernet ports, four USB 2.0 ports, DVI-I display interface, and support for either E-bus or K-bus I/O terminals. An internal 1-second UPS provides data security during power loss. Designed for PLC and motion control applications with or without visualisation, it includes Beckhoff’s TwinCAT 3 runtime (XAR) and runs Windows 10 IoT Enterprise 2019 LTSC.

Ideal for use in robust environments, the CX5140-0175 meets stringent EMC, shock, and vibration standards, and holds CE, UL, and optional ATEX/IECEx approvals.
