BECKHOFF CX5240-N031-0002 Embedded PC

Description

The BECKHOFF CX5240-N031-0002 is a high-performance Embedded PC powered by an Intel Atom processor, designed to handle demanding PLC, motion control, and industrial communication tasks. Engineered for direct DIN rail installation within control cabinets, this compact controller combines processing power with modular expansion capabilities to serve as a reliable control core in modern automation architectures.

This specific variant features the integrated -N031 interface option, which adds an RS485 serial communication port to the hardware. Configured as a drop point without echo and with internal termination turned off, the serial port provides reliable point-to-point or multi-drop connectivity to legacy field devices, specialty sensors, and secondary industrial instruments via a standard 9-pin D-sub connection.

Features

• Intel Atom multicore processing technology optimized for real-time control applications.
• Integrated -N031 serial interface option supporting RS485 communication protocols.
• 9-pin D-sub socket connector for secure and standardized serial connection.
• Pre-configured serial settings: drop point configuration, without echo, and termination disabled.
• Direct DIN rail mounting design for space-saving integration into industrial control panels.
• Compatible with modular Beckhoff I/O systems for versatile fieldbus and signal connection.

Applications

• Industrial PLC and machine control systems requiring centralized computing.
• Serial communication networks linking controllers with RS485-compliant devices and instruments.
• Control cabinet installations with restricted space demanding efficient thermal and physical footprints.
• Data acquisition, communication gateway, and protocol conversion applications.

Technical Specifications

Installation Guidelines

1. Verify that the model number on the device matches your system requirements (CX5240-N031-0002).
2. Ensure all electrical power sources to the control cabinet are switched off and locked out before starting work.
3. Align the unit with the 35 mm DIN rail and press firmly until the locking mechanism snaps securely into place.
4. Connect your RS485 serial communication cable to the 9-pin D-sub socket, ensuring the cable shield is grounded correctly.
5. Perform electrical and grounding system checks before energizing the device for configuration.

Replacement Recommendations

When replacing an existing controller with the BECKHOFF CX5240-N031-0002, ensure a complete backup of the active PLC project, configuration files, and system settings has been successfully saved. Verify that the replacement hardware matches the target system revision and that serial parameters (such as station address, baud rate, and parity) are properly initialized in your TwinCAT configuration before returning the system to operational service.
