Product description

Siemens 6ES7 516-3AN01-0AB0 is a central processing unit from the SIMATIC S7-1500 series with the type designation CPU 1516-3 PN/DP. Siemens documents 1 MB of integrated work memory for the program and 5 MB for data. Typical bit processing time is 10 ns. A SIMATIC Memory Card is required, and one card slot is provided. The integrated display has a diagonal of 6.1 cm and is operated by six keys. The hardware functional status is specified as FS03 in the technical data. The CPU has three separate paths for industrial communication. The first interface operates as PROFINET IRT with an integrated 2-port switch. A second PROFINET RT interface and a PROFIBUS interface are also provided. Two IO Controllers and one DP master are integrated. The I/O address range comprises 32 kB each for inputs and outputs. Memory capacity, network connections and fieldbus functionality are assigned to the exact order number in the Siemens data sheet. The supply rating is 24 V DC. Siemens specifies a permissible range from 19.2 to 28.8 V and a rated current consumption of 0.85 A. Typical power loss is 7 W. For horizontal installation, the documented ambient temperature range is 0 to 60 °C. The housing measures 70 x 147 x 129 mm and the device weight is approximately 845 g. These values distinguish this version from predecessor, successor and F-CPU variants. CPU type, memory, communication interfaces, supply data, I/O capacity and mechanical dimensions are documented separately. The series assignment and all numerical data refer expressly to 6ES7 516-3AN01-0AB0.

What applies if an item develops a defect within 14 days?

For the condition categories “Used, removed from an installation” and “New, old stock”, the contractual 14-day right of return in the event of a defect applies. The defect must occur within 14 calendar days after delivery and be reported in text form within the same period.

In particular, the REHA tamper-evident seal must remain fully intact and our RMA approval is required before return. In an accepted case, we decide between replacement and refund. Details in Section 11 of the Terms.

Which shipping methods and delivery times are available?

The shipping method, shipping cost and estimated delivery time are confirmed for the specific order. Depending on the item, destination and urgency, we can check parcel, express or freight shipping as well as collection.

A delivery date is binding only if we expressly confirm it as binding.

Which payment terms apply?

The payment terms stated in the checkout or order confirmation apply. Depending on the order and customer, payment is made in advance or against invoice.

International deliveries and deliveries to new customers are generally made against advance payment unless we expressly confirm another payment arrangement.

Can I return an item ordered incorrectly or found incompatible?

No. There is no general B2B right of return, exchange, cancellation or withdrawal. Incorrect or duplicate orders and a lack of suitability or compatibility with the customer’s installation are not covered by the contractual 14-day right of return in the event of a defect. Details in Section 12 of the Terms.

Can I request individual pricing for several items?

You may request an individual quotation for several items or larger quantities. We then check availability and pricing for the specific requirement; there is no entitlement to a quantity discount. Open the quick enquiry.

Do you also purchase industrial spare parts?

Yes. You can offer us automation and drive components for purchase. Please provide complete type numbers, quantities, condition details and photographs where possible.
