Replacement & Compatibility FAQ
Q: Can I use a third-party EM AE04 clone instead of the original 6ES7288-3AE04-0AA0?
A: Yes, in most cases. Pin-compatible clones work with S7-200 SMART CPUs, but accuracy, EMC performance, and long-term reliability may vary. For critical process applications, the original Siemens module is recommended.
Q: Is the 6ES7288-3AE04-0AA0 compatible with the S7-200 (classic) series?
A: No. This module is designed exclusively for the S7-200 SMART series. The classic S7-200 uses a different expansion bus (EM 231 series).
Q: Can I mix AE04 and AE08 modules on the same CPU?
A: Yes, as long as the total number of expansion modules does not exceed 6 and the total analog I/O count stays within CPU limits.
Q: What software is required to configure this module?
A: STEP 7-Micro/WIN SMART V2.4 or later. The analog I/O wizard simplifies channel configuration.
Q: Do you provide a test report or certificate of conformity?
A: Yes. Documentation is available upon request for all orders. Contact support@konmask.com.
