All PLC Direct products come with a 1-year warranty. The warranty is issued by PLC Direct. Warranty coverage commences at the date of purchase. The warranty is for mechanical defects or failures not caused by human factors including but not limited to (a) incorrect installation, (b) operating the unit in sub-optimal conditions or in scenarios not recommended by the manufacturer, (c) poor unit maintenance, etc. The warranty does not cover programming or software related issues.
If the product is eligible for PLC Direct’s warranty coverage and the customer encounters an issue with the product, we will request the item is shipped to us for diagnosis and examination. Regardless of the cause of product issues, the customer will bear responsibility for the cost of shipping the unit to PLC Direct for evaluation. Where the unit was damaged by human factors, we will offer a repair or replace quote; in cases where damage was caused by human factors, the customer is responsible for the cost of shipping the repaired/replaced unit from PLC Direct to the customer. Where the unit was not damaged by human factors but is covered by PLC Direct’s warranty, we will repair or replace the unit at our cost (or, in rare cases, refund you your purchase); in such cases, PLC Direct will bear the cost of shipping the repaired or replaced product back to the customer. It is up to PLC Direct’s discretion whether to repair, replace, or refund the customer in such cases. Diagnoses can take time to complete based on technician availability and the complexity of diagnosis.
In no event shall PLC Direct be liable for any damages except actual damages up to, but not exceeding, the amount paid to us for the product, including we shall not be liable for any consequential or indirect damages or lost profits whether or not advised of same.
PLC Direct offers free shipping worldwide. Product ship from a various warehouses worldwide based on the customer's and the product's location. The estimated delivery date on the product page is PLC Direct's best estimated assuming a US-based shipping destination.
Regardless of where the product is shipping from, PLC Direct covers all duties for US-based shipping destinations. For non-US-based shipping destinations, customers are responsible for duties as appropriate.
PLC Direct's focus is on balancing price with lead time. Some but not all products can be expedited. If you have questions about delivery ETAs, please contact our team.
