Allen-Bradley 1771-DMC Control Coprocessor Module: Supply Continuity Strategy for Discontinued PLC-5 Components

The Allen-Bradley 1771-DMC is a Control Coprocessor Main Module designed for the PLC-5 programmable controller platform — a workhorse of industrial automation that powered manufacturing lines, oil & gas facilities, and heavy process industries for decades. Rockwell Automation has officially discontinued the PLC-5 product family, making the 1771-DMC one of the most actively sought-after legacy modules on the global industrial spare parts market.

Procurement Specifications

Every 1771-DMC unit supplied by DriveKNMS undergoes functional verification prior to shipment. Our quality process includes visual inspection, board-level assessment, and where applicable, power-on testing. We do not list units we cannot verify.

• RFQ terms review: Commercial terms are confirmed during RFQ review based on model, condition, documentation, quantity and destination.
• Export Compliance: We issue full commercial export documentation including commercial invoice, packing list, and certificate of origin. All shipments comply with applicable export control regulations.
• Multi-Currency Payment: We accept USD, EUR, HKD, and CNY. T/T bank transfer, PayPal, and trade finance arrangements available for qualified buyers.
• Global Logistics: Shipments via DHL Express, FedEx International Priority, and UPS Worldwide. Typical transit: 3–7 business days to North America, Europe, Southeast Asia, and the Middle East. Tracking provided on all shipments.
• Customs Support: We provide HS code documentation and can assist with import declaration requirements for most major markets.

Sourcing discontinued Rockwell Automation components from the secondary market carries real risk — counterfeit parts, misrepresented condition, and suppliers who disappear after payment. DriveKNMS operates as a structured industrial parts distributor with verifiable sourcing networks across North America, Europe, and Asia-Pacific.
