Confirm the complete system—not only the model number
Industrial components can differ by series, firmware, voltage, network, terminal base, memory, accessories and approvals. A matching front label does not by itself guarantee a drop-in replacement.
Send the existing system or application information when compatibility matters.
State quantity, preferred condition, destination and required delivery date.
Include a clear nameplate photo when the revision is uncertain.
Know what is being quoted
The offered condition and inspection scope should be written into the quotation. Do not assume every source uses condition terms in the same way.
New product

Unused surplus
Confirm packaging, storage evidence, label condition and included accessories.
Refurbished product
Confirm the refurbishment source, functional test scope, cosmetic condition and warranty.
Used product
Request clear photographs and available inspection or functional-test information.
Technical references
Manufacturer documentation should be used for engineering, installation, safety and certification decisions. This page supports identification and sourcing; it does not replace the manufacturer manual.
