RFQ Information

Siemens automation hardware is commonly identified by a complete order number, hardware version and application context. Sharing these details helps distinguish visually similar components that may differ in electrical ratings, interfaces, firmware or supported functions.

For maintenance and retrofit work, include the installed model and the result the replacement must deliver. For new projects, add the control task, power data, communication protocol, operating environment and required quantity.

FAQ

Buyer Questions

01What information should I send for a quotation?

Send the complete Siemens order number or model, quantity, preferred condition and destination country. Add the required delivery timing when the request is connected to a shutdown or project schedule.

02How can I identify the correct Siemens part number?

Use the full order number from the nameplate, including suffixes and hardware details where shown. A clear nameplate photo can help when only part of the identifier is available.

03Can you help with a replacement for installed equipment?

Yes. Provide the installed model, electrical data, connected system, required function and any space or software limitations. These details help determine whether an alternative needs engineering changes.

04What should be confirmed before selecting a drive or motor?

Motor power, voltage, current, speed, torque, duty cycle, feedback device, mounting arrangement and control method should match the application. Existing drive and motor nameplate data is especially useful for replacement work.

05How are availability and lead time handled?

Availability and lead time are confirmed against the exact model, quantity, condition and delivery destination at the time of quotation. They are not treated as fixed values for every request.

06Do you support project quantities and repeat purchasing?

Project lists, maintenance requirements and repeat orders can be coordinated with consistent model references, quantities and destination details. Send the available part list even when some technical information is still being collected.
