BECKHOFF CX2040-0120 Basic CPU Module

Description

The BECKHOFF CX2040-0120 is a high-performance Embedded PC basic CPU module belonging to the CX2000 series. Equipped with an Intel Core i7 quad-core processor, this module is engineered to handle intensive industrial control, visualization, and motion control applications. It provides the core processing intelligence for complex automation tasks within a compact, DIN-rail-mounted form factor.

This CPU module features rich onboard connectivity, including two independent Gigabit Ethernet interfaces, four USB 2.0 ports, and a DVI-I port for display connections. Storage and operating system deployment are managed via a CFast card slot, while persistent data is secured using an integrated 128 kB NOVRAM. The system dynamically interfaces with field I/O systems through a power supply module, offering automatic recognition of both E-bus (EtherCAT Terminals) and K-bus (Bus Terminals).

Features

• Equipped with an Intel Core i7 2715QE 2.1 GHz quad-core processor.
• 4 GB DDR3 RAM and 128 kB of persistent NOVRAM integrated onboard.
• Supports 20 GB or 40 GB CFast cards (depending on operating system configuration).
• Dual independent RJ45 Gigabit Ethernet ports for high-speed network communication.
• Flexible I/O integration with automatic recognition of E-bus and K-bus architectures via the power supply module.
• Integrated ball-bearing cooling fan featuring real-time speed monitoring.

Applications

• High-performance PLC and complex multi-axis motion control tasks.
• Industrial visualization and HMI systems requiring high-resolution DVI-I outputs.
• Centralized communication gateways and edge controllers in distributed manufacturing networks.
• Data logging and storage-heavy automation applications.

Technical Specifications

Installation Guidelines

1. Ensure that the entire installation environment is de-energized and protected against accidental restart before mounting the module.
2. Mount the CX2040-0120 CPU module horizontally on a standard 35 mm DIN rail in a control cabinet with an IP20 or higher protection rating.
3. Ensure adequate ventilation clearance around the integrated cooling fan to prevent heat buildup.
4. Connect the compatible CX series power supply module directly to the right-hand side of the CPU module.
5. Connect the required fieldbus and network cables to the RJ45 and optional interfaces as specified.
6. Verify all terminal connections and ensure the battery is securely inserted before applying power.

Replacement Recommendations

When replacing a BECKHOFF CX2040-0120, ensure that the CFast storage card is backed up or transferred to the replacement unit to preserve system configurations, licenses, and program execution files. Verify that the twin power supply module is operational and configured to match the E-bus or K-bus mapping of your existing system architecture.
