I have a DTI communications box with part number sie027335.

The door hinges on this box are damaged, and I would like to replace them.

I'm frustrated by the difficulty in finding this information. Thank you for your help.

Hello;

This is one of the few references I found on the web about the product you are looking for:

Look on page 18 of the catalog, you will see various communciation boxes offered by Siemens in France. Yous will be the Coffret de Communication Simbox Grade 3 TV 8RJ45.

The link is to a  French catalog, the other reference is to Amazon.fr who sell these communication boxes:

https://www.amazon.fr/SIEMENS-Coffret-communication-Grade-8RJ45/dp/B07NLV7L9B

This being a Siemens forum, you might expect us to know about all Siemens worldwide products, but this is not the case. Siemens is a huge conglomerate operating in many countries, and we volunteers from this Siemens forum only have knowledge and access to Siemens Automation products. 

I hope the links provided can help you find the provenance of this equipment and therefore allow you to ask the source about spare parts.

Hope this helps,

Daniel Chartier
