Power Rail
To reduce wiring and installation costs, Power Rail is the optimum solution. The Power Rail
is a DIN mounting rail with plastic insert, that delivers power to the devices (24 V DC)
and transfers bus signals and a collective error message.
The Power Rail is factory-equipped with cover and end caps. These parts cover empty
and open segments of the Power Rail. Thus, the Power Rail is protected from contamination.
Additionally the cover and end caps prevent that electrically conductive parts come in contact
with the Power Rail.
Power Rail is available in two versions:
Power Rail UPR-03
The Power Rail UPR–03 has 3 conductors.
•
2 conductors for power
•
1 conductor for collective error messaging
Power Rail UPR-05 (only for KFD2-WAC2-(Ex)1.D)
The Power Rail UPR–05 has 5 conductors.
•
2 conductors for power
•
1 conductor for collective error messaging
•
2 conductors for serial data exchange
