Fieldbus connector

Note!
This connector can only be used for a PROFIBUS-PA device.
The connection technology of PROFIBUS-PA allows measuring devices to be
connected 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:
x Field devices can be removed, replaced or added at any time during normal
operation. The communications will not be interrupted.
x This simplifies installation and maintenance significantly.
x Existing cable infrastructures can be used and expanded instantly, e.g. when
constructing new star distributors using 4-channel or 8-channel junction boxes.
Prosonic Flow 93 can therefore be supplied with the option of a ready-mounted fieldbus
connector. Fieldbus connectors for retrofitting can be ordered from E+H as a spare part
(see Page 119).
