B&R X20CP1382 X20 Series Intel x86 Compact CPU Controller

Product Overview

The X20CP1382 (X20CP1382) is a high-performance, compact CPU controller from the B&R X20 system, engineered to deliver robust processing power for complex industrial applications. Equipped with an Intel x86 400 MHz compatible processor and an integrated I/O processor, this module excels in executing background I/O tasks without taxing the main CPU cycles. Its versatile onboard connectivity—including Ethernet, POWERLINK with poll-response chaining, and CAN bus—makes it an ideal choice for mid-scale automation in sectors such as renewable energy, high-speed packaging, and precision metalworking. The X20CP1382 combines 30 digital I/O points and 2 analog inputs into a single fanless unit, providing a space-saving footprint that maintains peak reliability in demanding 24/7 production environments.

Technical Configuration

The hardware architecture of the X20CP1382 is designed for longevity and maintenance-free operation. It features 256 MB DDR3 SDRAM and 2 GB of onboard eMMC flash memory, with an impressive 40 TB guaranteed write endurance for data-heavy logging. A key architectural advantage is the inclusion of a 32 kB FRAM for remanent variables, ensuring critical process data is retained for over 10 years without a battery. The module includes one modular interface slot, allowing for fieldbus expansion while maintaining its compact form factor. Communication is highly flexible, supporting RS232, USB 2.0, and X2X Link, with a built-in real-time clock backed up for at least 300 hours via internal capacitors.

Technical FAQs

How does the integrated I/O processor improve system performance?

The integrated I/O processor manages data point processing independently in the background. This offloads the primary Intel x86 CPU, allowing it to focus entirely on the control logic and complex algorithms, resulting in more stable task class cycle times as low as 1 ms.

Is a battery required to maintain remanent data during power loss?

No, the X20CP1382 utilizes 32 kB of FRAM for remanent variables, which provides data retention for more than 10 years without the need for a battery, reducing long-term maintenance costs and environmental impact.

What are the requirements for high-speed signal lines on this module?

To ensure signal integrity for the high-speed digital inputs and outputs, shielded lines must be used. The maximum permissible line length for these high-speed signals is 20 m to prevent electromagnetic interference from affecting the 1 ms cycle precision.

Engineering & Installation Guide

• Shielding and Grounding: For the integrated CAN bus and high-speed I/O, ensure the shield is connected to a low-impedance ground at the entry point of the control cabinet. The X20 system relies on the DIN rail for functional grounding; ensure the rail is unpainted and properly bonded to the system earth.

• Flash Memory Management: While the 2 GB eMMC is rated for 40 TB of total writes, engineers should optimize logging routines. In applications requiring 21.9 GB/day of data writes, the flash drive is designed to last at least 5 years. For extremely data-intensive applications, consider using the modular slot for external storage expansions.

• Thermal and Space Planning: The module is fanless and dissipates approximately 5.5 W to 8.6 W depending on I/O load. For optimal cooling, maintain the standard X20 mounting orientation (vertical). The package includes the right-hand end cover plate and three 16-pin terminal blocks; ensure these are installed to protect internal circuits from debris and maintain IP20 integrity.
