B&R X20CP0420
ARM Cortex-A9 processor with 166 MHz-compatible and integrated I/O processor Onboard Ethernet Integrated switch for efficient wiring 2x onboard USB 128 MB DDR3 SDRAM 256 MB onboard flash drive Fanless No battery Extremely compact The controllers in the X20 Compact-S family are both powerful and compact. The fanless, battery-free design of these controllers means they are completely maintenance-free. The X20CP0420 is equipped with an ARM Cortex-A9 166 MHz compatible processor, 128 MB RAM and 256 MB built-in flash drive. The FRAM for storing remanent variables has 8 kB available. With Ethernet, USB and RS232, the controller offers plenty of communication options. An optional RS485 or CAN interface is available. The Ethernet interface is equipped with 2 female RJ45 connections. Both connections result in an integrated switch. This makes daisy-chain wiring easy.
