Product description

Siemens 6ES7 315-2EH14-0AB0 is a CPU 315-2 PN/DP in the SIMATIC-S7-300 family. It is intended primarily for installed systems that require a compact S7-300-CPU with both classic MPI/PROFIBUS DP connectivity and integrated PROFINET. Siemens specifies 384 KB of integrated working memory, a first MPI/DP interface supporting up to 12 Mbit/s and a second Ethernet/PROFINET interface with a 2-port switch. This combination is relevant when an existing STEP-7 project, distributed PROFIBUS I/O and Industrial Ethernet communication must be retained together. A Micro Memory Card is required as the storage medium, and Siemens specifies STEP 7 V5.5 or later as the engineering basis. The documented firmware family is V3.2. Rated current consumption is 750 mA, typical no-load current consumption is 150 mA and typical power loss is 4.65 W. The PROFINET interface supports 10/100 Mbit/s over RJ45, an integrated switch, IO Controller and IO Device functionality, and PROFINET MRP with a typical switchover time of 200 ms after a line interruption. The combined RS-485 MPI/PROFIBUS DP interface remains important for existing S7-300 networks. The module measures 40 mm in width, 125 mm in height and 130 mm in depth, with an approximate weight of 340 g. Before replacement, compare the exact MLFB, memory size, interfaces, firmware family, Micro Memory Card and STEP-7 project because visually similar CPU-315 variants can differ in all of these areas.

FAQ

Frequently asked questions

Contact us
Is there a warranty?

Yes. We provide a 14-day functional warranty for used items. The component must be functional on arrival, and the warranty applies only while the warranty seal remains undamaged. If a fault occurs within 14 calendar days, please contact us in writing. Depending on availability, we will either provide a replacement or refund the full purchase price after the item has been returned. Further details are set out in the terms and conditions supplied with our quotation.

How quickly do you ship, and which shipping options are available?

We normally dispatch available items immediately and, in many cases, on the same working day. For urgent requirements or machine downtime, we will identify the fastest suitable option and can confirm a specific delivery window on request. Express shipping and collection from our premises are also possible by arrangement. We ship worldwide using reliable parcel and freight carriers; freight shipments may require additional preparation to ensure safe delivery.

Is there a guarantee?

Yes, we provide a 14-day functional guarantee for used items. This means the component must be operational when received.

Please note that the guarantee only applies when the warranty seal is undamaged.

If a defect occurs within 14 calendar days, please contact us in writing. Subject to availability, we will provide a replacement or refund the full purchase price after return.

Further details are provided in the terms and conditions supplied with your quotation.

How quickly do you dispatch and which shipping options are available?

We generally dispatch immediately - in many cases on the same working day. For particularly urgent requirements or machine downtime, we find a suitable solution as quickly as possible and provide a specific delivery window on request.

Express shipping or collection from our premises is also possible, depending on the situation. State your requirements during the ordering process or contact us directly.

We ship worldwide and work with reliable shipping partners, from parcel services to freight forwarding. Freight shipments normally require some preparation so the goods arrive safely and undamaged.

Which payment methods are available?

Payment is normally made by bank transfer against invoice. Payment is due within 10 calendar days of receiving the goods.

As a rule, we offer purchase on account for all customers. In individual cases, such as new customers or particularly high-value components, we may agree advance payment. This decision is made individually and communicated transparently.

Can we return items if they were ordered incorrectly?

Because we sell exclusively to business customers (B2B), there is no general right of return and no consumer right of withdrawal.

Please note that returns of functioning goods are generally excluded. In justified exceptional cases, we can assess an individual solution, but this is not the standard procedure.

Is there a discount when ordering several items?

For larger order quantities or several items of one type, we can offer individual discounts.

Simply send us a quick enquiry - we check availability and will gladly prepare a tailored quotation with quantity pricing.

Do you also purchase industrial spare parts?

Yes, we also purchase automation components, such as frequency inverters, PLC assemblies, panels, servo motors and CPUs. Components from Siemens, Lenze, Schneider Electric, Control Techniques or Heidenhain are especially sought after, and other brands are also possible.

The process is straightforward: email us an inventory list or overview photos at info@reha-industriekomponenten.de. We calculate a market-based purchase price and send you an offer.
