Product description

Siemens 6ES7 314-6EH04-0AB0 is a compact SIMATIC S7-300 CPU 314C-2 PN/DP for machine and plant control with integrated I/O. Siemens documents 192 KB work memory, 24 digital inputs, 16 digital outputs, 4 analog inputs, 2 analog outputs and one Pt100 channel. It also provides 4 high-speed counters with up to 60 kHz. The first communication interface supports MPI and PROFIBUS DP at up to 12 Mbit/s. The second interface is Ethernet PROFINET with an integrated 2-Port-Switch. The unit is supplied with 24 V DC. Operation requires a Micro Memory Card and two 40-pin front connectors. Siemens assigns the order number to CPU 314C-2 PN/DP from firmware V3.3 and specifies a net weight of 0.785 kg. The combination of CPU, integrated digital and analog channels, and counter functions makes the module suitable for compact control tasks where additional I/O modules should be reduced. For replacement, the complete order number, firmware version, memory size, I/O assignment, front connectors and network interfaces must match the existing hardware configuration. Another CPU 314C may differ in interfaces or integrated I/O despite a similar designation. Siemens 6ES7 314-6EH04-0AB0 is therefore especially suitable for targeted maintenance and retrofit of existing S7-300 stations whose STEP-7 project and wiring are configured for this PN/DP version. Direct comparison using the exact MLFB prevents confusion with neighboring variants. Siemens has listed the product in phase-out since 01.10.2023; the exact hardware assignment remains permanently decisive for service work during ongoing plant operation.

The CPU has 24 digital inputs, 16 digital outputs, 4 analog inputs, 2 analog outputs and one Pt100 channel.

Which network interfaces does CPU 314C-2 PN/DP provide?

It provides MPI/PROFIBUS DP at up to 12 Mbit/s and Ethernet PROFINET with an integrated 2-Port-Switch.

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.
