Product Description:
The X20CP3484-UPS is a central processing module produced by B&R Automation for the X20 Fieldbus Input Output Modules series. Installed at the head of an X20 node, it executes user logic, manages time-critical tasks, and provides uninterruptible control during a power dip. By combining CPU resources with local and remote I/O access, the unit coordinates motion, safety, and standard automation functions within distributed machine architectures.
Its computing platform uses a 266 MHz Celeron-compatible processor that handles deterministic control loops and communication protocols. The controller is equipped with 32 MB SDRAM for real-time code execution, while a separate CompactFlash slot allows removable storage for application files and other data. Three interface slots, two USB ports, and an RS-232 channel rated up to 115.2 kbit/s support common communication and service connections. The shortest cyclic task can be scheduled at intervals as short as 800 µs, which suits high-speed packaging, printing, or inspection duties where precise timing is required. One X2X backplane link distributes power and data to adjacent slice modules, and each USB receptacle can supply 0.5 A for service tools or low-power sensors.
Nonvolatile application variables are stored in 1 MB SRAM, allowing machine counters and recipes to remain available through a brief mains outage. The electronics draw only 10.5 W from the 24 V rail, while field devices are supplied through a galvanically isolated I/O output of 24 VDC. Relay contacts can switch up to 10 A, enabling direct actuation of solenoids or indicator lamps without intermediate relays. The dedicated X2X bus power budget of 7 W limits the number of neighboring modules and keeps load planning straightforward. The housing measures 200 mm in width, 85 mm in depth, and 99 mm in height, so it fits in a single row in a standard control cabinet while maintaining airflow for convection cooling.
