B&R 7CP476-020.9 Programmable Logic Controller Module

7CP476-020.9 is a B&R System 2003 CPU module that functions as the PLC’s central processing core, designed to drive up to four screw‑in expansion modules for I/O, communication, and control functions within a compact backplane. The unit provides 750 KB of RAM for program and data storage, is powered from a 24 V DC supply, and includes built‑in RS‑232 and CAN interfaces to support serial diagnostics, programming, and fieldbus connectivity in harsh industrial environments. This CPU is intended for deterministic control tasks where tight timing and reliable operation are essential, such as packaging lines, material handling systems, and process skids, where the ability to consolidate multiple I/O modules under a single controller simplifies wiring and improves maintainability. As part of the System 2003 family, the 7CP476-020.9 integrates with B&R Engineering tooling for configuration, programming, and diagnostics, and is typically deployed in installations that require modular expansion, straightforward replacement, and long‑term availability of spare parts in automation projects.
