The Siemens 6ES7288-1CR40-0AA1 is a SIMATIC S7-200 SMART CR40s compact CPU with 24 integrated 24 V DC digital inputs, 16 relay outputs, and 20 KB of program/data memory.
- CPU CR40s
- 24 DI 24 V DC; 16 relay DO
- 85 to 264 V AC at 47 to 63 Hz
- 20 KB program/data memory
It executes the STEP 7 Micro/WIN SMART user program, reads the 24 onboard binary input signals, and commands 16 field outputs for forty-point compact relay control without an expansion-module requirement. Its relay channels switch approved AC or DC loads within the published contact limits. The compact CRs design uses integrated RS485 communication and fixed onboard I/O. It is suited to standalone production fixtures and utility equipment.
Important Notice: Use the complete 6ES7288-1CR40-0AA1 code and verify the physical nameplate, firmware, project, accessories, and current Siemens documentation before installation or replacement.

Read the exact Siemens S7-200 SMART documentation before use. Verify 6ES7288-1CR40-0AA1, CPU CR40s, power, I/O wiring, firmware, and project from the physical installation.
1
Identity: Match the complete 6ES7288-1CR40-0AA1 MLFB, CPU CR40s marking, hardware, and firmware
2
Power: Verify 85 to 264 V AC at 47 to 63 Hz and isolate all sources before wiring or removal
3
I/O: Observe every channel voltage, current, group common, polarity, and protective-device limit
4
Project: Back up and match the STEP 7 Micro/WIN SMART configuration, addresses, communications, and retentive data
5
Panel: Use DIN-rail mounting, protective earth, segregation, ventilation, and orientation limits from Siemens
