If you want to gear a company to the future, you’ve got to provide answers to the following questions: What do you stand for? What sets you apart? How will you achieve longterm success? And that’s what we’ve done. Vision 2020 is paving the way to a successful future. And to make it happen, we’re focusing on the following topics:

1. A clear mission
A mission expresses a company’s self-understanding and deﬁnes its aspirations. “We make real what matters.” That’s our aspiration. That’s what we stand for. That’s what sets us apart. A reflection of our strong brand, it’s the mission that inspires us to succeed.

2. A lived ownership culture

One engine of sustainable business is our ownership culture, in which every employee takes personal responsibility for our Company’s success. “Always act as if it were your own Company” – this maxim applies to everyone at Siemens, from Managing Board member to trainee.

3. A consistent strategy
With our positioning along the electriﬁcation value chain, we have knowhow that extends from power generation to power transmission, power distribution and smart grid to the efﬁcient application of electrical energy. And with our outstanding strengths in automation, we’re well equipped for the future and the age of digitalization. Vision 2020 deﬁnes an entrepreneurial concept that will enable our Company to consistently occupy attractive growth ﬁelds, sustainably strengthen our core business and outpace our competitors in efficiency and performance. It’s our path to long-term success. And we’re measuring our progress: seven overarching goals support this aim.

We’ll be working on the three areas outlined above. They describe the key factors that are enabling us to lead Siemens into a successful future. Throughout this process, we will gear all our actions to the requirements of our customers, our owners and our employees as well as to the values of society. I personally intend to ensure that the next generation will inherit a better Company. That’s my vision. That’s my responsibility. That’s my promise.

SITOP PSE200U

Electronic protection of 24 V DC load
circuits with fast fault localization
The SITOP PSE200U selectivity module distributes the load
current across several 24 V DC load circuits and monitors
them reliably for overload and short-circuit conditions. The
electronics permit brief current peaks caused, for example,
by high inrush currents, but isolate 24 V DC load circuits in
the event of an extended overload. This is ensured even on
high-resistance lines and in the case of "creeping" shortcircuits. In such cases, miniature circuit breakers fail to trip,
or trip too late, even if the power supply unit could deliver
the required tripping current. The SITOP PSE200U continues to supply 24 V DC to the load circuits not affected by
an overload – a feature which avoids a possible total system failure. The single-channel message version facilitates
rapid, channel-specific fault localization via just one digital
input at the PLC.

Your benefits at a glance

■ Reliable tripping regardless of cable lengths or crosssections

■ Four 24 V DC load circuits in two versions with adjustable output current range of 0.5 to 3 A or 3 to 10 A

■ Easy configuration thanks to individual setting of
maximum channel current using potentiometers

■ Two versions for remote diagnostics:
common signaling contact or single-channel
signaling

■ Evalution for modules with single-channel signaling
via free of charge SIMATIC S7 or SIMOTION function
blocks

■ LEDs for fast on-site fault localization

■ Remote reset possible from a central location
■ Simple commissioning thanks to manual switch on/
off of channels using reset button

24 V DC

■ Voltage measure points for output currents (1 V = 1 A),
disconnecting of load circuit is not required

■ Sequential connection delay of individual 24 V DC
load circuits reduces total inrush current

■ Sealable transparent cover protects against maladjustment of tripping current and sequential delay
As electronic protection, the SITOP PSE200U selectivity module
switches faulty 24 V DC load circuits off immediately, and continues
to supply the other 24 V DC load circuits without any interruption.
