Advantages through energy efficiency
Overview of the energy management process
We offer you a unique portfolio for industrial energy manage-
ment, using an energy management system that helps to opti-
mally define your energy needs. We split up our industrial
energy management into three phases – identify, evaluate,
and realize – and we support you with the appropriate hardware
and software solutions in every process phase.
The innovative SIRIUS industrial controls products can also
make a major contribution to the energy efficiency of a plant
(www.siemens.com/sirius/energysaving)
.
The 3UG48 monitoring relays for IO-Link contribute to the energy
efficiency throughout the plant as follows:
•
Shutdown in the event of no-load operation
(e.g. pump no-load operation)
•
Reactive-power compensation by means of power factor
monitoring
•
Load shedding of predefined loads in the event of current
overshoots
■
Application
The use of SIRIUS monitoring relays for IO-Link is particularly
recommended for machines and plant in which these relays, in
addition to their monitoring function, are to be connected to the
automation level for the rapid, simple and fault-free provision of
the current measured values and/or for remote parameterization.
The monitoring relays can either relieve the controller of monitor-
ing tasks or, as a second monitoring entity in parallel to and in-
dependent of the controller, increase the reliability in the process
or in the system. In addition, the elimination of AI and IO modules
allows the width of the controller to be reduced despite signifi-
cantly expanded functionality.
