Genuine Allen-Bradley 1772-LN2 CPU Module | Mini-PLC Series – Verified Source
The Allen-Bradley 1772-LN2 is a cornerstone CPU module within Rockwell Automation’s legacy Mini-PLC-2 family — a platform that continues to power critical manufacturing, process control, and discrete automation systems worldwide. As OEM support winds down and production of this model has been discontinued, the secondary market has become saturated with counterfeit units, refurbished modules misrepresented as new, and grey-market parts with unknown service histories. Sourcing an unverified 1772-LN2 carries real operational risk: unexpected downtime, failed audits, and safety incidents in regulated environments.
At Konmask, every Allen-Bradley 1772-LN2 we supply is individually inspected and authenticated before shipment. We source exclusively through traceable supply chains and apply a documented 4-step verification process to confirm genuine origin, functional integrity, and specification compliance. Our inventory carries full traceability documentation — including Certificate of Conformance (COC), packing list, and country-of-origin declaration — so your procurement team can close the loop with confidence. When you order from Konmask, you receive an authentic, verified, and fully documented Allen-Bradley component.

Our 4-Step Quality Verification Process
- Step 1 — Source Authentication: We verify the supply chain origin of every unit, cross-referencing lot codes, date codes, and manufacturer markings against known genuine Allen-Bradley production standards. Units with inconsistent or missing markings are immediately rejected.
- Step 2 — Physical Inspection: Each module undergoes a detailed visual inspection covering PCB condition, connector integrity, label authenticity, housing finish, and component placement. High-resolution photos are taken and archived per unit.
- Step 3 — Functional Testing: Where applicable, modules are bench-tested for power-up response, communication handshake, and basic I/O scan cycle. Test results are logged and available as a Test Report upon request.
- Step 4 — Documentation Package: Every shipment is accompanied by a Certificate of Conformance (COC), packing list, country-of-origin (COO) declaration, and — on request — photographic inspection records. This documentation supports your incoming inspection and audit requirements.
