The Siemens 6ES7288-1SR30-0AA1 is a SIMATIC S7-200 SMART CPU SR30 with 18 digital inputs and 12 digital relay outputs on board. It is the AC/DC/Relay version: the CPU is powered from the 85-264 V AC line, the inputs are 24 V DC and the outputs are dry relay contacts rated 2 A, so it drives contactors, solenoid valves, lamps and small motors directly without interposing relays.
It carries 18 KB of program memory and 12 KB of data memory, an on-board Ethernet port for programming and HMI communication and an RS485 port for Modbus RTU or USS drive control, and it accepts up to six expansion modules plus one signal board.
The S7-200 SMART is the controller Siemens built for small and medium machines: packaging lines, bottling and filling machines, textile and plastics machinery, water treatment skids, elevators and simple process skids. It is programmed with the free STEP 7-Micro/WIN SMART software over a standard Ethernet cable, and it pairs with the SIMATIC SMART LINE touch panels for a complete low-cost control package. Because the platform is installed in very large numbers across the Middle East, a spare CPU is the part a maintenance team needs most often when a controller fails.

Frequently asked questions
Is this the same as CPU SR30 with an order number ending -0AA0?
No. 6ES7288-1SR30-0AA1 is the current V2 hardware. Order numbers ending -0AA0 are the earlier first-generation units. Programs transfer upward, but always quote the exact order number printed on the module you are replacing so we ship the matching version.
Can I connect an HMI panel to this CPU?
Yes. The Ethernet port connects directly to a SIMATIC SMART LINE panel, and the RS485 port can also carry a serial HMI or Modbus RTU.
How many expansion modules can I add?
Up to six EM expansion modules on the right-hand side, plus one SB signal board that clips into the front of the CPU.
What software do I need to program it?
STEP 7-Micro/WIN SMART, which Siemens provides free of charge. You connect over a standard Ethernet patch cable; no special programming adapter is needed.
