Fieldbus connector
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 Hauser as a spare part
