BUY WITH A CLEAR DESCRIPTION
Know the Condition.
Confirm the Scope.
For legacy parts, the condition, packaging, test information and quotation terms matter as much as the part number.
Unused Legacy Stock
Described as new surplus or new old stock where verified. Original packaging may be sealed, open or unavailable; the offered condition is stated in the quotation.
Condition and Testing Explained
Refurbished and used equipment are identified separately. Available test information, warranty and acceptance terms are confirmed for the particular offer.
Review the Existing Unit
Selected modules can be assessed for repair. Feasibility, parts availability, test coverage and applicable repair warranty are reviewed before proceeding.

Before Ordering a Replacement.
Do you have every Siemens S5 module in stock?
No. This is a sourcing and repair service. We check availability, condition and delivery for each enquiry and confirm the offer before an order is placed.
Does “new” mean newly manufactured?
Our legacy S5 offers may include unused surplus or old stock. We identify that condition explicitly and confirm packaging and warranty terms. We do not describe surplus as newly manufactured equipment.
Can a replacement CPU be fitted without transferring the program?
That depends on the controller, memory arrangement and existing configuration. Send the CPU details and available backup information so we can assess the required transfer and testing work.
Can you quote repair and replacement options together?
Yes, where feasible. We can review the faulty unit and check available replacements so you can compare scope, condition, lead time and cost.
