Specification

The Siemens SIMATIC S7-200 SMART CPU SR30 (6ES7288-1SR30-0AA1) is a compact yet powerful PLC controller designed for cost-sensitive automation applications where relay outputs are required for switching inductive loads like contactors, solenoids, and small motors. This AC-powered CPU integrates 18 digital inputs and 12 relay outputs, offering a balanced I/O count for standalone machines or small process lines. With its built-in Ethernet port, the SR30 enables seamless integration into modern factory networks, supporting PROFINET, Modbus TCP, and easy connection to Siemens HMI panels. The 30 KB memory is partitioned for program and data, ensuring efficient execution of ladder logic, function blocks, and structured text. Engineered for reliability, this CPU operates in harsh industrial environments from -20°C to +60°C and is fully compliant with CE, UL, and RoHS standards. Whether you are upgrading a legacy system or building a new control panel, the S7-200 SMART SR30 delivers proven performance with quick delivery from stock.
