!

Note! 
The connector can only be used for PROFIBUS PA devices.

The connection technology of PROFIBUS PA allows measuring devices to be connected to the 
fieldbus via uniform mechanical connections such as T-boxes, distribution modules etc.

This connection technology using prefabricated distribution modules and plug-in connectors offers 
substantial advantages over conventional wiring:
• Field devices can be removed, replaced or added at any time during normal operation. 

Communication is not interrupted.

• Installation and maintenance are significantly easier.
• Existing cable infrastructures can be used and expanded instantly, e.g. when constructing new 

star distributors using 4-channel or 8-channel distribution modules.

The device can therefore be supplied with the option of a ready-mounted fieldbus connector. 
Fieldbus connectors for retrofitting can be ordered from Endress+Hauser as a spare part.
