Product Overview
The Siemens 6ES7288-1CR40-0AA0 is a core component of the SIMATIC S7-200 SMART series, serving as a Compact CPU CR40. This all-in-one controller is an ideal choice for standalone machines, smaller systems, and basic automation tasks that require a powerful yet economical PLC. Its compact design minimizes the need for extensive control cabinet space, making it perfect for distributed or space-constrained applications.
The CPU CR40 comes equipped with a generous set of integrated I/Os, including 24 digital inputs for sensing various discrete signals and 16 digital outputs utilizing relay contacts. These relay outputs offer robust switching capabilities (up to 2A per output) and provide electrical isolation, allowing direct connection to both DC and AC loads such as contactors, solenoid valves, and indicator lights. The CPU is powered by an AC supply (85-264V AC), simplifying power integration. Beyond its integrated I/O, the CPU CR40 features an integrated Ethernet port for programming, HMI communication, and PROFINET RT capabilities, ensuring modern connectivity. It also supports Signal Boards for additional communication ports (like RS485/RS232) or specialized I/O. With built-in motion control functions and a real-time clock, this CPU provides a comprehensive and flexible foundation for a wide range of industrial automation challenges.
