CX5230-N031-0003 BECKHOFF Embedded PC Intel Atom Series

Product Overview

The CX5230-N031-0003 (CX5230N0310003) is a high-performance, DIN rail-mountable embedded PC designed for demanding industrial automation environments. Engineered with a fanless Intel Atom multi-core processor, this unit provides the computational power necessary for complex PLC, Motion Control, and visualization tasks within a compact footprint. In large-scale manufacturing facilities, power generation plants, and advanced water treatment systems, the CX5230-N031-0003 serves as the central intelligence hub. By integrating the RS485 interface as a factory-installed option, this specific configuration facilitates seamless connection to legacy serial devices and decentralized peripheral equipment, significantly reducing system latency and preventing unplanned downtime in mission-critical operations.

Technical Configuration

The CX5230-N031-0003 utilizes a modular hardware architecture that balances processing efficiency with robust connectivity. This specific "N031" variant features a built-in RS485 interface, pre-configured with a 9-pin D-sub socket. The interface is set as a drop point with echo enabled and termination turned off, allowing for flexible integration into existing multi-drop bus topologies. The Intel Atom CPU architecture ensures low power consumption and minimal heat dissipation, while the solid-state storage and absence of rotating parts enhance its vibration and shock resistance. This PC is optimized for TwinCAT software environments, enabling deterministic control and high-speed data processing across EtherCAT and serial protocols simultaneously.

Technical Specifications

Technical FAQs

How do I enable the termination resistor if my network topology requires it?

The N031 interface in this model is shipped with termination off. To activate termination for end-of-line signals, you must utilize an external D-sub connector with a built-in termination switch or manually bridge the required pins on the 9-pin socket according to the Beckhoff pinout diagram.

Can this unit run third-party Windows applications alongside TwinCAT?

Yes, the CX5230 supports standard Windows Embedded Compact or Windows 10 IoT Enterprise operating systems. However, to maintain real-time performance for industrial control, third-party software should be allocated to specific CPU cores to avoid interrupting the TwinCAT real-time environment.

What is the maximum cable length supported by the integrated RS485 interface?

The RS485 interface adheres to standard industrial limits, typically supporting up to 1200 meters at lower baud rates. For high-speed data transmission in environments with high electromagnetic interference, the use of shielded twisted-pair cables and proper grounding is mandatory to ensure signal integrity.

Engineering & Installation Guide

• Serial Network Integrity: When integrating the CX5230-N031-0003 into a serial network, ensure that the RS485 cable shielding is grounded at a single point to prevent ground loops. Given that this model is configured with "Echo On," the software must be programmed to handle the reception of its own transmitted characters to prevent data buffer overflows.

• Thermal Management: Although the unit is fanless, it relies on natural convection. It must be installed in a vertical orientation on the DIN rail to allow air to flow through the cooling fins. Maintain a minimum clearance of 30 mm above and below the device to prevent thermal throttling when operating near the 60 deg C limit.

• Power Supply Stability: Use a stabilized 24 VDC power source. In environments with high-frequency switching noise (such as near Variable Frequency Drives), install an isolation transformer or a dedicated line filter for the PC power input to protect the internal electronics from voltage spikes.
