Fieldbus connector
The connection technology of PROFIBUS-PA allows measuring devices to be con-
nected to the fieldbus via uniform mechanical connections such as T-boxes, junction
boxes, 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 opera-
tion. The communications will not be interrupted.
• This simplifies installation and maintenance significantly.
• Existing cable infrastructures can be used and expanded instantly, e.g. when con-
structing new star distributors using 4-channel or 8-channel junction boxes.
The Prosonic Flow 93 can therefore be supplied with a ready-mounted fieldbus connec-
tor. Fieldbus connectors for retrofitting can be ordered from E+H as a spare part.
Note:
For the PROFIBUS-DP option, is it advisable to use the system components (plug-and-
sachet connection) from the Company BARTEC.
