B&R Industrial Automation X20CP1583 CPU Module

The B&R X20CP1583 CPU Module is a compact, Atom-based central controller for the B&R X20 PLC system. It pairs an Intel Atom-compatible 333 MHz CPU with an integrated I/O processor to coordinate program execution and I/O traffic across the X20 backplane. The module runs on 24 V DC and is designed for a fanless, IP20 enclosure environment, making it suitable for machine control cabinets and compact automation cells. It provides 128 MB DDR2 SDRAM for program and data storage, and exposes interfaces for communication and I/O: one Ethernet port for LAN or device networking, one Powerlink interface for the X20 I/O bus, and one RS-232 serial port for legacy or device interfacing. The X20CP1583 serves as the main controller in the X20 system and can function as a bus controller to manage X20 I/O modules on the network. Connection is via the X20 backplane and 12-pin X20TB12 terminal blocks for peripheral wiring; the module is commonly documented with hardware revisions such as Rev F0 for the CPU/BUS CONTROLLER variant. This CPU module is part of B&R's X20 family, designed to be used with Automation Studio for programming, diagnostics, and project deployment, delivering a compact, low-power control solution for small to mid-size automation tasks while keeping a straightforward upgrade path within the X20 platform.
