This isolated barrier is used for intrinsic safety applications. It
transfers digital signals (NAMUR sensors/mechanical
contacts) from a hazardous area to a safe area.

The proximity sensor or switch controls a form A normally
open relay contact for the safe area load. The normal output
state can be reversed using switch S1. Switch S2 allows
output II to be switched between a signal output and an error
message output. Switch S3 enables or disables line fault
detection of the field circuit.

During an error condition, relays revert to their de-energized
state and LEDs indicate the fault according to NAMUR NE44.
A unique collective error messaging feature is available when
used with the Power Rail system.
Due to its compact housing design and low heat dissipation,
this device is useful for detecting positions, end stops, and
switching states in space-critical applications.

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 2016-06-14 09:22
Date of issue 2016-06-14
240654_eng.xml
Power Rail and Profile Rail must not be fed via the device terminals of the individual devices!
