Accessories
Power feed module KFD2-EB2
The power feed module is used to supply the devices with 24 V DC via the Power Rail. The fuse-protected power feed module
can supply up to 150 individual devices depending on the power consumption of the devices. Collective error messages received
from the Power Rail activate a galvanically-isolated mechanical contact.
Power Rail UPR-03
The Power Rail UPR-03 is a complete unit consisting of the electrical insert and an aluminium profile rail 35 mm x 15 mm. To
make electrical contact, the devices are simply engaged.
Profile Rail K-DUCT with Power Rail
The profile rail K-DUCT is an aluminum profile rail with Power Rail insert and two integral cable ducts for system and field cables.
Due to this assembly no additional cable guides are necessary.
Release date 2012-07-31 16:00
Date of issue 2015-02-16
236982_eng.xml
Power Rail and Profile Rail must not be fed via the device terminals of the individual devices!
