More about selecting S7-400 accessories parts

Accessories, Frames, and Interface Modules

For the S7-400, we supply central and expansion frames, IM interface modules, synchronization modules, interconnect cables, fans, batteries, memory cards, and other accessories.

When it comes to accessories, we always need to know the part they are intended for. Based on the type of CPU, frame, or module, we verify the compatibility of the memory card, fan, battery, interface module, or synchronization component. For S7-400H systems, we also verify that the synchronization modules and cables are the correct type.

New, refurbished, and discontinued parts from our warehouses

For current SIMATIC S7-400 parts, we first check the availability of new, genuine SIEMENS parts. We have access to an extensive network of industrial parts warehouses in Europe and around the world, so we can also check for refurbished, discontinued, and hard-to-find variants.

Spare Parts Warehouse for Industrial Automation — Spare Parts Warehouse for Industrial Automation.

Warehouse for Industrial Parts and Automation Components — Warehouse for industrial parts and automation components.

Verifying Accessory Compatibility

Depending on the type of CPU, frame, or module, we will verify that the accessories—such as memory cards, batteries, fans, interfaces, or synchronization modules—are correct.

Frequently Asked Questions

Can you help me choose compatible accessories?

Yes. We will verify the correct model and availability based on the CPU or module order number.

How quickly can you deliver the part?

Delivery times depend on the specific part and warehouse. Thanks to our access to numerous warehouses, we can typically arrange delivery within a few days; for urgent needs, we can offer express delivery within a matter of hours. For urgent requests, call us immediately—we can arrange express delivery of selected parts day or night.

Is the order number sufficient for the inquiry?

Yes. Ideally, provide the full number from the label and the quantity you need; a photo of the label will also be helpful for replacements or repairs.
