Our 4-Step Quality Verification Process
Every 6ES7288-1ST40-0AA0 unit shipped by Konmask.com passes through the following documented checks:
- Source Authentication — Units are procured exclusively from authorised distributors or verified OEM-surplus channels. Supplier credentials are reviewed and retained on file.
- Physical Inspection — Label integrity, hologram verification, housing condition, connector pin alignment, and date-code consistency are checked against SIEMENS reference standards.
- Functional Bench Test — Power-on test, I/O point continuity check, and firmware version confirmation are performed where test equipment is available.
- Packaging & Documentation Audit — Original SIEMENS packaging, manual inserts, and CE/UL markings are verified before final sealing and dispatch.
Test records are available upon request for orders above MOQ thresholds. Contact support@konmask.com for documentation packages.
