PR-03 Power Rail
UPR-03 Power Rail
KFD2-EB2 power feed module
The KFD2-EB2 power feed module and the PR-03 or the UPR-03 Power Rail are used to supply the devices with 24 VDC and
at the same time to evaluate combined fault indications.
Each power feed module monitors and provides protection for groups of as many as 100 individual devices. The PR-03 Power
Rail is an insert component for the DIN rail. The UPR-03 Power Rail is a complete unit consisting of an electrical insert and an
aluminium DIN rail measuring 35 mm x 15 mm x 2000 mm. The devices are simply snapped in place to make electrical
contact.
If a Power Rail is not being used, power can be supplied to the devices directly through the device terminals.
