Procurement Specifications

Every A1S52B unit shipped by DriveKNMS is subject to the following compliance and logistics standards:

• Export Documentation: Full commercial invoice, packing list, and certificate of origin provided for customs clearance. We support export compliance requirements for regulated industries including oil & gas and defense-adjacent manufacturing.
• Multi-Currency Payment: USD, EUR, CNY, HKD accepted. T/T (bank transfer), PayPal, and trade finance arrangements available for qualified buyers.
• Global Logistics: DHL Express, FedEx International Priority, and UPS Worldwide available. Typical transit time: 3–7 business days to North America, Europe, Southeast Asia, and the Middle East.

Sourcing discontinued industrial automation components is a specialist activity. The risks — counterfeit parts, misrepresented condition, non-compliant documentation — are real and consequential. Here is why procurement teams at industrial facilities across 40+ countries work with DriveKNMS:

• Part Number Verification: Our technical team cross-references part numbers against Mitsubishi Electric's official documentation to prevent substitution errors — a common and costly mistake when sourcing legacy components.
• Responsive RFQ Process: Standard RFQ response time is within 24 hours on business days. Urgent requests (production-down situations) are prioritized and typically responded to within 2–4 hours.

Q: How are commercial terms confirmed?
A: Commercial terms are confirmed during RFQ review based on model, quantity, destination, documentation and sourcing route.

Q: Is the A1S52B compatible with my existing MELSEC-A CPU?
A: The A1S52B is compatible with all A1S-series CPU modules. If you are unsure about compatibility with your specific configuration, send us your system layout and our technical team will confirm before you commit to a purchase.
