HART Multiplexer System KFD*-HM*-16
Installation
Mounting on DIN rail with
Power Rail
Note

The Power Rail UPR-03-* is an insert for a DIN rail which Pepperl+Fuchs has
developed for this application.
The Power Rail provides two leads for power supply of the modules and one lead for
centralized error messages. The devices of the K-System are supplied with power
through these two leads.

Figure 4.2
Standard devices of types KFD2-... and KCD2-... have gold-plated contacts to
connect to the power supply rails of the Power Rail. By snapping it onto the DIN rail,
the device automatically receives power. Thus separate wiring of the power supply is
eliminated. An included cover provides for the mechanical and electrical protection
of unused spaces. Furthermore, any reserved spaces are automatically connected to
the power supply.
Third-party devices which can be mounted on a DIN EN 60715 mounting rail can
easily be mounted on the Power Rail as well. Mixed devices from different device
manufacturers are thus possible.
Figure 4.3
When supplying power via the Power Rail, the wiring effort is greatly reduced.
Moreover, there is the option of the centralized error message and redundant power
supply. Failure of the power supply is indicated through the message contact of the
power supply component.
