Part replacement, BOM review and machine selection.

A discontinued part, a mixed-brand bill of materials (BOM) or a new machine calls for a different review. Choose the starting point that matches your project.

  1. Send

    BOM, part number, drawing, or nameplate photo.

  2. Separate

    Published, candidate, or missing, marked line-by-line.

  3. Ask

    Voltage, I/O, protocol, environment facts required.

  4. Quote

    Reviewed model, quantity, terms, existing documents.

  5. Support

    Review engineers answer commissioning questions.

What should I send for an HMI and PLC proposal?ReadHide

Send the machine function, required I/O, communication protocol, screen size, quantity and target date. Existing part numbers, drawings, programs and cabinet photos help us separate a straightforward supply request from work that needs programming, wiring or validation.

Can a Kinco PLC replace a Siemens or Mitsubishi PLC?ReadHide

A Kinco controller may be a candidate replacement, subject to engineering review. The I/O, network, program, safety functions, cabinet wiring and commissioning plan must be checked before a model is selected. Existing TIA Portal, GX Works and other ecosystem projects are not converted automatically; logic, tags, screens, drivers and settings may need to be rebuilt and tested.

How are stock, price and product documents handled?ReadHide

We check the exact SKU, revision, quantity and destination before quotation. We do not publish live stock counts or fixed ship dates. Available datasheets, certification records and order documents are matched to the quoted model rather than inferred from a product family.
