Specification

The B&R X20CP1684 is a compact, fanless controller module that delivers exceptional performance for real-time automation and motion control applications. Integrating an Intel Atom E3915 processor with 400 MHz clock speed, 512 MB LPDDR4 SDRAM, and 1 MB L2 cache, this unit ensures fast instruction cycle times of 0.0044 µs and a minimum task class cycle of 400 µs. The X20CP1684 supports POWERLINK V2 for deterministic communication, along with Ethernet, RS232, USB, and X2X Link interfaces, making it ideal for distributed I/O and drive systems. Its robust power supply design includes a 24 VDC input with integrated fuse, reverse polarity protection, and a dedicated X2X Link power output of 7 W (derated to 5 W above 55°C). The controller also features comprehensive diagnostics via LED indicators for CPU, Ethernet, POWERLINK, CompactFlash, battery, and temperature, ensuring easy maintenance and troubleshooting. With certifications including ATEX Zone 2, cULus, DNV, and CCS, the X20CP1684 is engineered for reliability in demanding industrial environments.
