Runs compact machine logic using the onboard fixed digital I/O set.
Product Overview
6ES7288-1CR30-0AA1 is the Siemens SIMATIC S7-200 SMART CPU CR30s AC/DC/Relay execution with 18 integrated digital inputs and 12 integrated relay outputs.
Siemens documents 12 KB program memory, 8 KB user-data memory and 2 KB retentive memory. Expansion modules and signal boards are not supported on this compact execution.
The exact 0AA1 identity prevents confusion with an incomplete or different suffix during service and purchasing.
Performance
Switches approved field loads through twelve relay outputs.
Provides a 24 V sensor supply within the published 300 mA maximum.
Retains program, user-data and retentive-memory boundaries documented for the CR30s.

System Integration
- Back up the approved project, communication parameters and retentive-value record.
- Photograph the 0AA1 label, AC supply and every I/O terminal before disconnection.
- Keep 6ES7288-1CR30-0AA1 distinct from submitted 0AA0 identities until label evidence is confirmed.
- Test all used I/O, interlocks, relay loads and safe restart after commissioning.
Applications
- Compact machines with eighteen digital inputs and twelve relay outputs.
- Standalone control panels where modular expansion is not required.
- Relay-load applications with verified inrush, suppression and protection.
- Exact spare replacement for an installed 6ES7288-1CR30-0AA1.
FAQ
How should 6ES7288-1CR30-0AA1 be distinguished from a 0AA0 code?
Use the complete physical label and Siemens ordering documentation; do not drop or alter the final revision characters.
What project material should be retained for 6ES7288-1CR30-0AA1?
Keep the editable project, compiled backup, software release, communication settings, symbol data and approved restore instructions.
Can 6ES7288-1CR30-0AA1 accept an expansion module?
No. The CR30s compact execution does not support signal-board or expansion-module additions.
What causes premature relay-output problems on 6ES7288-1CR30-0AA1?
Uncontrolled inrush, insufficient suppression, excessive switching duty or incorrect branch protection can damage relay contacts.
What should be included in a 6ES7288-1CR30-0AA1 quotation request?
Include the full label, project-software release, load schedule, terminal photographs, quantity and destination.
