The Siemens SIMATIC S7-200 SMART CPU SR40 (6ES7 288-1SR40-0AA0) is a powerful, compact micro-PLC designed for small to mid-size automation systems and control panels. It combines 24 DI, 16 relay DO, and onboard analog I/O (2AI/2AO) in a single CPU, reducing the need for extra modules and panel space.
With an integrated Ethernet port, the SR40 supports fast programming, HMI/SCADA connectivity, and PLC-to-PLC communication. Built-in high-speed counters and PTO/PWM make it suitable for motion control, encoder feedback, and precise output control.
This PLC is widely used by panel builders, machine manufacturers, and OEMs for applications like packaging machines, filling systems, conveyors, water treatment panels, and process skids. Expansion capability with S7-200 SMART modules allows flexible system growth while keeping costs low.
