CX8031 by Beckhoff is engineered to bring high reliability and control flexibility to compact industrial environments. Powered by a 400 MHz Arm9™ processor and equipped with 64 MB DDR2 RAM and a 512 MB microSD card for flash memory, it supports consistent PLC execution via TwinCAT 2 on Windows Embedded CE 6. Its integrated 1-second UPS ensures data is protected during short power interruptions, critical for machine safety and process continuity.
This Embedded PC features a D-sub 9-pin socket with shielding, along with interfaces for USB and Ethernet (RJ45), enabling reliable device communication and remote access. The CX8031 automatically detects E-bus or K-bus I/O connections, simplifying installation and expansion. Built for industrial durability, it operates between 0°C and 55°C and includes a battery-backed real-time clock for accurate time tracking, even during outages.
It’s passively cooled, IP20-rated, and certified with CE, UL, ATEX, IECEx, and cFMus, making it suitable for deployment in standard and hazardous environments. The 24 V DC power supply with a ±20% range offers robust tolerance to voltage fluctuations. With support for up to 2 A I/O current supply and a maximum power consumption of 3 W, the CX8031 Embedded PC delivers energy-efficient operation without compromising performance. Engineers trust it for machine control, building automation, and process monitoring due to its seamless integration, modularity, and compliance with EN 60068 and EN 61000 industrial standards.
