Our 4-Step Quality Verification Process
Every 1756-ENBT/A unit shipped from Konmask.com passes through our standardized verification protocol before it reaches you:
- Step 1 — Source Authentication: We verify the supply chain origin and cross-reference manufacturer lot codes and date codes against Rockwell Automation’s published records.
- Step 2 — Physical Inspection: Each module is inspected for label integrity, connector condition, PCB markings, and housing authenticity. Counterfeit indicators are checked against known reference units.
- Step 3 — Functional Bench Test: Where applicable, modules are powered up and tested for backplane communication, Ethernet link establishment, and firmware version confirmation.
- Step 4 — Packaging & Documentation Audit: Units are repackaged with anti-static protection, and all accompanying documentation (datasheet, test report, certificate of conformance) is included in the shipment.

Authenticity & Trust FAQ
Q: How do I know this is a genuine Allen-Bradley module?
A: Every unit is sourced from authorized industrial distributors or verified secondary-market channels. We provide lot code documentation and, upon request, a certificate of conformance. We welcome third-party inspection before shipment.
Q: Is this new, refurbished, or used?
A: Unless explicitly stated otherwise in the listing title, all units are new-in-box (NIB) or new-surplus (factory-sealed, never installed). Refurbished units are always clearly labeled as such.
Q: Can you provide a datasheet or wiring diagram?
A: Yes. The official Rockwell Automation publication 1756-UM004 (EtherNet/IP Modules in Logix5000 Control Systems) is available on request. Contact [email protected].
Q: What is your return policy?
A: We offer a 30-day return window for DOA (dead-on-arrival) units with full replacement or refund. Modules must be returned in original packaging with all documentation.
Q: Do you offer warranty?
A: All new units carry a 12-month Konmask seller warranty covering manufacturing defects. This is in addition to any applicable Rockwell Automation OEM warranty.
