Product Description:

The CX2040-0135-3002 is an embedded PC manufactured by Beckhoff within the CX Embedded PC Systems series. It is intended to serve as the control nucleus of machine lines or building systems, executing PLC logic and motion sequences directly on the DIN rail. By merging PC-based computation with fieldbus connectivity, the device eliminates the need for a separate rack computer and streamlines cabinet space in industrial automation installations.

Processing tasks are handled by an Intel Core i7-2715QE running at 2.1 GHz, and its architecture provides 4 cores so deterministic workloads can be split across real-time and user partitions under TwinCAT 3 XAR. Program code and runtime data reside in 4 GB DDR3-RAM, while a 40 GB CFast module stores the operating system, boot project, and historical logs. Nonvolatile process counters are preserved in the 128 kB NOVRAM section, which is independent of main power. For networking, the unit offers 2 x RJ45 Gigabit Ethernet ports, allowing separate machine and enterprise segments or ring topologies. Four USB 2.0 ports with 500 mA available at each connection support service keyboards, scanners, or drive cloning. A DVI-I output supports monitors at up to 1920 × 1200, enabling local HMI panels without an additional graphics box. All electronics fit inside a 144 × 99 × 91 mm housing that clips directly onto the terminal bus.

The controller is supplied from a 24 V DC source that may vary from -15% to +20%, and its internal consumption peaks at 32 W when every interface is active. Passive convection cooling keeps the electronics functional over an ambient span of -25 °C to +60 °C, while storage is permitted from -40 °C to +85 °C when the unit is not powered. The aluminum enclosure carries an IP 20 rating, so it must be mounted inside a control cabinet to limit dust exposure. This cabinet-mounted design suits industrial control panels where space is limited and fanless operation is preferred.
