Product description

Siemens 6GK7443-1EX11-0XE0 is a SIMATIC-S7-400 communications processor CP 443-1 for connecting an S7-400 station to Industrial Ethernet. The exact Siemens Industry Mall data clearly assigns the MLFB to the S7-400 family. The module has an Industrial Ethernet interface with 10 to 100 Mbit/s. RJ45 and AUI are available as physical connections, with the AUI connection being a 15-pin Sub-D socket. ISO, TCP/IP, UDP and RFC1006 as well as S7 communication and open communication are supported. The documented communication services also include Fetch/Write and Send/Receive with or without RFC1006. Siemens lists up to 48 S7 connections and up to 64 connections for open communication. The maximum user data length is 8 KiB over ISO/TCP and 2 KiB over UDP. The supply is provided with 5 V DC from the S7-400 backplane bus. The typical current consumption is 1.4 A, the power loss is 8.6 W. Protection class IP20 and permissible operation from 0 to 60 °C require installation in a suitable control environment. The compact S7-400 module occupies a single assembly width and measures 25 × 290 × 210 mm. The complete order number clearly separates this older connection combination from later CP versions. For replacement, complete MLFB, rack compatibility, RJ45-/AUI usage, network topology, IP or ISO configuration, communication connections and the existing STEP-7 project must be checked together. The configured connection resources, partner addresses and the communication blocks used must also match the old CP version. It must not be exchanged for newer CP-443-1 variants based solely on the function name because connection and configuration details may differ.

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.

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.
