BECKHOFF CX2040-0143 CX2000 Series Basic CPU Module

Description

The BECKHOFF CX2040-0143 is a high-performance Embedded PC basic CPU module designed for DIN rail mounting in demanding automation systems. Equipped with an Intel Core i7 2715QE quad-core processor running at a 2.1 GHz clock frequency, this controller delivers the robust computational capacity required for complex PLC, Motion Control, and industrial visualization applications.

This controller incorporates a high-density hardware architecture featuring 4 GB of non-expandable DDR3 RAM and 128 kB of integrated, non-volatile NOVRAM for reliable persistent data storage. Built-in physical interfaces include two independent Gigabit Ethernet ports, one DVI-I graphic connection, and four USB 2.0 ports. A slot for an optional communication interface allows integration with different fieldbus protocols and networking architectures.

System expansion and I/O integration are executed via a matching CX2100 power supply module, enabling automatic bus recognition for both E-bus (EtherCAT Terminals) and K-bus (Bus Terminals). An active cooling system with an integrated, monitored ball-bearing fan ensures stable thermal performance across a wide operating temperature range from -25 to +60 degC.

Features

• Intel Core i7 quad-core processor for multi-threaded control tasks
• 4 GB internal DDR3 RAM main memory
• 128 kB integrated NOVRAM for reliable persistent data protection without batteries
• Two independent Gigabit RJ45 interfaces for high-speed network communication

Installation Guidelines

1. Ensure that all system power sources are completely de-energized before mounting, wiring, or servicing the hardware.
2. Mount the CX2040-0143 securely on a standard 35 mm DIN rail within an IP20-rated dry control enclosure.
3. Align and connect the companion CX2100 series power supply module directly to the left side of the CPU module.
4. Insert a compatible CFast flash memory card containing the operating system and the TwinCAT configuration into the boot slot.
5. Verify that the RJ45 network lines and peripheral cables are properly shielded to mitigate electromagnetic interference.
6. Apply 24 V DC to the connected power supply module and verify system initialization through the integrated status LEDs.

Replacement Recommendations

When replacing a BECKHOFF CX2040-0143 unit, always preserve or back up the original CFast card to retain software licenses, TwinCAT boot projects, and operating system configurations. Completely de-energize the assembly before swapping the module to protect against voltage spikes on the internal bus interfaces.
