4.2 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 UPR-03
The Power Rail UPR–03 has 3 conductors.
•
2 conductors for power
• 1 conductor for collective error messaging
