Our 4-Step Quality Verification Process
Every Allen-Bradley 1771-IMD shipped from Konmask.com passes through our rigorous 4-step inspection protocol before dispatch:
- Step 1 — Visual Inspection: Physical examination of housing, connectors, label integrity, and board condition. Any signs of damage, corrosion, or tampering result in immediate rejection.
- Step 2 — Authenticity Check: Cross-referencing serial numbers, date codes, and manufacturer markings against Rockwell Automation documentation to confirm genuine origin.
- Step 3 — Functional Bench Test: Where applicable, modules are powered and tested for correct I/O response, backplane communication, and LED status indication.
- Step 4 — Packaging & Documentation: Units are packed in anti-static ESD-safe materials with inspection records included. A certificate of inspection is available upon request.
