Description

Industrial automation setups demanding multi-core processing power utilize the Beckhoff CX2040-0135 to coordinate complex PLC, NC, and CNC control systems. Operating as a high-performance Basic CPU module, this device integrates an Intel Core i7 processor with four cores running at 2.1 GHz to execute intensive computational tasks directly within the TwinCAT 3 runtime (XAR) platform level 70 environment. Its architecture accommodates dual independent Gigabit Ethernet ports, multiple USB interfaces, and a high-resolution DVI-I output for direct HMI configuration. Designed for DIN rail mounting, this processing unit interfaces seamlessly with Beckhoff I/O systems, automatically identifying connected EtherCAT Terminals (E-bus) or Bus Terminals (K-bus) via the adjacent power supply module.

Features

Equipped with a quad-core Intel Core i7 2715QE 2.1 GHz processor for multi-threaded industrial control applications.
Includes 4 GB DDR3 RAM and integrated 128 kB NOVRAM persistent memory for reliable data storage.
Features dual RJ45 ports supporting 10/100/1000 Mbit/s Ethernet interfaces.
Automatic recognition and direct interface with E-bus (EtherCAT) and K-bus (Bus Terminal) systems.
Integrated ball-bearing cooling fan with active speed monitoring to prevent thermal throttling.
Support for CFast flash storage cards up to 40 GB dependent on the installed operating system.

Applications

High-speed machine control and CNC machining lines.
Multi-axis motion control and robotics synchronization.
Complex distributed industrial automation systems.
Power plant control and substation monitoring.

Installation Guidelines

DIN Rail Mounting: Mount securely onto a standard 35 mm DIN rail (EN 60715) inside a dry, dust-free control cabinet.
Ventilation Clearance: Ensure adequate free space above and below the module to allow unhindered air flow from the integrated cooling fan.
Earthing: Maintain a low-impedance functional earth connection via the DIN rail to guarantee correct EMC performance and noise immunity.
Power Supply Integration: Always couple with a compatible Beckhoff power supply module (e.g., CX2100 series) to feed power to the CPU and the adjacent I/O bus terminals.
