The Siemens 6ES7288-1CR40-0AA0 is a SIMATIC S7-200 SMART CPU CR40 that provides forty onboard I/O points in an economical fixed-I/O CPU.
- CPU CR40
- 24 DI 24 V DC; 16 relay DQ
- 85 to 264 V AC at 47 to 63 Hz
- 125 x 100 x 81 mm
In an S7-200 SMART automation station, it reads 24 V DC binary input states and switches sixteen relay output circuits. It works with the verified CPU or expansion-bus configuration, terminal blocks, field power, sensors, and actuators defined for the exact article number. The module is used in compact conveyors, pumping skids, and fixed-sequence machinery.
Important Notice: Use the complete 6ES7288-1CR40-0AA0 code and verify the physical nameplate, current Siemens documentation, field wiring, project, and accessories before installation or replacement.
Apter Power 6ES7288-1CR40-0AA0 Manuals and Guides
Important Notice: These are two separate Apter Power documents prepared from the manufacturer-published Siemens information named in each document. Confirm the physical nameplate, current Siemens documents, and host-system requirements before installation or replacement.
Standalone sequence control
Executes machine logic while processing 24 input states and 16 relay commands
Relay load coordination
Controls approved contactors, solenoids, lamps, and interposing relays within published limits
Fixed-I/O equipment
Provides 40 onboard points where the machine design does not require separate I/O expansion
Industrial machine panels
Applies to compact conveyors, pumping skids, and fixed-sequence machinery when the exact MLFB, firmware, and project are matched
Read the exact Siemens S7-200 SMART documentation before use. Verify 6ES7288-1CR40-0AA0, CPU CR40, power, I/O wiring, terminals, and project from the physical installation.
1
Identity: Match every character of 6ES7288-1CR40-0AA0 and the CPU CR40 marking to the physical nameplate and project
2
Power: Verify 85 to 264 V AC at 47 to 63 Hz; isolate all energy sources before wiring, insertion, or removal
3
Signals: Observe every input/output voltage, current, common, group, polarity, isolation, and protective-device limit
4
Panel: Use documented DIN-rail mounting, clearances, protective earth, cable segregation, ventilation, and IP20 enclosure protection
5
Commissioning: Match firmware and STEP 7 Micro/WIN SMART project, back up the program and retentive data, then complete the machine-builder test procedure
