Product Description:
The CX1800-0202-0004 is a CPU extension produced by Beckhoff for the CX Embedded PC Systems series. Installed on a DIN rail beside standard CX power supply and I/O slices, it supplies the processing resources that let the controller execute PLC logic, motion tasks, and visualization in small and mid-range machines. By concentrating supervisory, networking, and data-logging functions on the same compact board, the module supports flexible industrial automation in cabinet-mounted systems without the footprint of a panel PC.
Processing is driven by a 500 MHz clocked AMD Geode LX 800 that pairs with 256 MB DDR-RAM to handle deterministic multitasking under real-time extensions in embedded control applications. A single 1 x RJ45 port provides 10/100 Mbit Ethernet for network access, PLC communication, and field-level protocols, and the internal 16-bit ISA (PC104) system bus links this CPU layer to digital and analog terminal blocks without gateways. The battery-backed RTC maintains timestamps through power loss, while a CF Type I/II expansion slot accepts removable storage for recipe files or operating system updates. Startup images earlier than version 1.30 are not supported.
The housing meets IP20, so it is intended for shielded control cabinets where conductive dust and moisture are excluded. Typical thermal dissipation is limited to 8 W, allowing passive convection cooling alongside other CX components. A minimum CompactFlash capacity of 1 GB is required for the licensed runtime and user programs that reside on the pre-installed Windows XP Embedded operating system. This image includes Beckhoff’s TwinCAT runtime, allowing fieldbus or HMI modules to be changed without shutting down the base CPU. The module also reports battery status so the RTC cell can be replaced before timekeeping is affected.
