Power feed modules 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 100 individual devices depending on the power consumption of the devices. A galvanically isolated mechanical
contact uses the Power Rail to transmit collective error messages.
Power Rail UPR-03
The Power Rail UPR-03 is a complete unit consisting of the electrical inset and an aluminium profile rail 35 mm x 15 mm. To
make electrical contact, the devices are simply engaged.
The Power Rail must not be fed via the device terminals of the individual devices!
