PROFIBUS PA M12 plug-in connector
Note!
This connector can only be used for a PROFIBUS PA device.
With PROFIBUS PA the connection system allows you to connect devices to the fieldbus
using standardised mechanical connections such as branches and distributor
elements. 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. Communications will not be interrupted.
• This simplifies mounting 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.
Optionally, the Liquiphant can be supplied from the factory with a pre-installed fieldbus
device plug-in connector. Field bus connectors for retrofitting can be ordered from E+H
as a spare part (see page 35).
