4.3.3 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:
Field devices can be removed, replaced or added at any time during normal
operation. The communications will not be interrupted.
This simplifies installation and maintenance significantly.
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).
