Prepare a PLC, servo and sensor replacement enquiry

A brand or model name alone is not enough to establish compatibility. Collect the existing equipment information and ask the supplier to state what has been checked and what still requires verification.

LUNA coordinates demand diagnosis, China supply-chain matching and Vietnam/local delivery. We work as a sourcing and service coordinator; we are not the equipment manufacturer.

Information to prepare

• What is the complete existing model number, version and machine application?
• Which drawings, interface information and relevant alarm records are available?
• Which functions must remain unchanged and who will review the proposed replacement?
• What commissioning window and acceptance evidence can the site provide?

What to agree before ordering

• A traceable list of existing parts and candidate replacements.
• A written compatibility review with unresolved items identified.
• An agreed configuration, commissioning and rollback responsibility.
• Confirmation of product provenance, quotation terms and support contacts.

Prepare your project enquiry

These guides describe the enquiry process. Product availability, suitability, price, delivery time, certifications and service coverage require confirmation for each project. Catalog publication alone is not a stock or performance guarantee.
