Product description

Siemens 6AG1 964-2AA04-4AB0 is a SIPLUS IF 964-DP interface module for SIMATIC S7-400. The module connects distributed I/O via PROFIBUS DP and adds an isolated RS-485 interface to compatible S7-400 CPUs. It can be used as a DP master by default and also supports operation as a DP device. The maximum data rate is 12 Mbit/s; depending on the CPU, up to 125 DP devices can be addressed. For cable planning, Siemens specifies up to 100 metres at 12 Mbit/s and up to 1.200 metres at 9.6 kbit/s. Supported communication functions include PG/OP communication, isochronous bus cycles, SYNC, FREEZE, and direct data exchange. A maximum of 244 bytes of input data and 244 bytes of output data can be transferred per DP device. The compact design measures 26 x 54 x 130 mm and weighs approximately 65 g, fitting the intended S7-400 interface slot. Typical power loss is 1 W. The documented bus services make the module suitable for established S7-400 architectures with distributed I/O. This is particularly relevant for installations with long PROFIBUS cables, existing diagnostic concepts, and fixed device addresses. The module is therefore suitable for maintenance, retrofit projects, and targeted replacement of an installed PROFIBUS DP interface. Before replacement, compare the complete order number, installed CPU, existing bus configuration, and STEP-7 project. Terminating resistors, connector pinout, and the configured data rate must also match the existing installation. Similar variants exist within the S7-400 and SIPLUS families, making an exact MLFB comparison and confirmation of the configured DP master or DP device role essential.

FAQ

Frequently asked questions

Contact us
What is Siemens 6AG1 964-2AA04-4AB0 used for?

The IF 964-DP adds an isolated PROFIBUS DP interface to compatible SIMATIC-S7-400-CPUs for connecting distributed I/O.

Which data rate does the IF 964-DP support?

The interface supports PROFIBUS DP data rates up to 12 Mbit/s and, depending on the CPU, up to 125 DP devices.

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.
