The B&R X20 series redefines industrial control by merging a high-performance compact PLC with a flexible distributed I/O system. This modular platform is engineered to deliver exceptional processing power, real-time communication, and robust reliability in the most demanding industrial environments. With the optional conformal coating (X20c series), it offers unparalleled protection against condensation and corrosive gases, ensuring maximum uptime and extended service life.

Compact Design and High-Density Modularity

The X20 system's innovative three-piece modular design – consisting of a bus module, electronics module, and terminal block – provides unmatched flexibility and serviceability. Controllers are available in ultra-compact widths starting from just 37.5 mm (including power supply), saving up to 50% of valuable cabinet space compared to conventional systems. The system integrates a standard set of 32 digital and analog I/O channels directly on the CPU, and can be expanded with an unlimited number of local or remote X20 I/O slices, allowing the system to scale precisely with application needs without replacing the core controller.

Unmatched Protection for Harsh Environments

For applications exposed to adverse atmospheric conditions, the X20c series features a specialized conformal coating on its electronics modules. This coating provides a robust barrier against condensation and corrosive gases, ensuring reliable operation even in challenging environments. The effectiveness of this protection is rigorously verified through standardized testing, including BMW GS 95011-4 for condensation and the 4-part corrosive gas test EN 60068-2-60, method 4. These tests are conducted in B&R's own ISO/IEC 17025 accredited lab and at certified external facilities, guaranteeing the durability and longevity of the system beyond standard requirements.

Extreme Real-Time Performance

Powered by x86 and Intel Atom processors ranging from 200 MHz to 1.6 GHz, the X20 PLC delivers the processing power required for complex control tasks. A standout feature is B&R's patented reACTION technology, which enables the integrated I/O channels to achieve response times as low as 1 microsecond (µs). This is accomplished through a function block library within the Automation Studio development environment, all while maintaining full compatibility with the IEC 61131-3 standard. This level of performance is critical for high-speed applications like registration control, precise labeling, and fast event counting.

Flexible and Open Communication

The X20 system is designed for seamless integration into any automation architecture. Standard communication interfaces include Ethernet, USB, RS232, and the real-time POWERLINK protocol. Optional interfaces such as RS485, CAN, PROFINET, EtherNet/IP, and Modbus RTU are available without increasing the controller's footprint. The onboard Ethernet interface supports daisy-chaining with an integrated switch, simplifying network cabling. Additionally, all CPUs can be upgraded with one or more interface slots from the standard X20 range, offering unparalleled connectivity for any fieldbus or network requirement.

Reliability and Global Certifications

Engineered for 24/7 operation, the X20 controllers are completely fanless and battery-free, making them maintenance-free and immune to the most common mechanical failure points. The entire system operates reliably across a wide temperature range of -25°C to +60°C. Its ruggedness is further validated by rigorous international certifications, including CE, UL, cULus, ATEX, and compliance with EN 61131-2. Critically, the X20 system has received prestigious maritime certification from Germanischer Lloyd (GL) and other major classification societies (ABS, BV, DNV, LR, KR, RINA), making it a trusted choice for offshore and on-deck applications.

Applications

The B&R X20 system's unique combination of compactness, extreme performance, and rugged reliability makes it ideal for a diverse range of applications, including:

• Harsh Environment Manufacturing (e.g., chemical, metal, and wood processing)
• Maritime and Offshore Systems (e.g., ship automation, offshore platforms)
• High-Speed Packaging and Converting Machinery
• Precision Material Handling and Robotics
• Food and Beverage Production with frequent washdowns
• Pharmaceutical and Life Science Equipment
