SITRAFFIC C840V
Traffic Controller
Designed for use
wherever there are
traffic signals using
new LED technology
Your Success is Our Goal
Helping the environment and your budget
Light signals with 40 V LED technology need
up to 90 % less power than conventional
signals with filament lamps. Depending on
the size of the city and the transport infrastructure, this is a lot of energy that neither
has to be generated, transported, consumed
nor, naturally, paid for either. This relieves
the environment and also your budget.
More safety at every intersection
The perfect combination –
legendary reliability and the
latest 40 V LED technology
Siemens has developed a new controller which is specially
designed for controlling 40 V LED signal heads. It is
called SITRAFFIC® C840V – and the name says a lot.
On the one hand, that it is a traffic controller from the
reliable SITRAFFIC C800 family. This means the same
tools, the same programming language and the same
easy handling.
On the other hand, the name shows that the unit has
been specially designed for new signal heads based on
40 volt LED technology.
We are convinced that this is a combination that users
all over the world will appreciate.
Perhaps also in your own area in the not too distant
future?
Lateral light, glaring sunshine and reflections
are problems that often make it necessary
for road users to look very closely at the traffic
signals to see what they are actually indicating. And, frequently, all they see is
phantom light. This new technology prevents
such situations. The signal heads have a
considerably more uniform field of illumination and are easier to see from the side.
An improvement in safety for all road users.
Traffic systems experience which pays off
Siemens has been improving the traffic
situation around the globe for over 100 years.
With products and systems of the most
variegated kinds and with solutions of all
degrees and levels of complexity. This
enormous fund of experience generates
direct advantages for all our customers. After
all, Siemens is fully aware of how important
(and how cost-effective in the long term)
the absolute reliability of traffic control
equipment is. Whatever the weather
and whatever the situation. The new
SITRAFFIC C840V traffic controllers are an
impressive demonstration of this level of
reliability.
Cologne looks to the future
Traffic signals with low-voltage LEDs (Light
Emitting Diodes) belong to the future. They
consume up to 90 % less energy, have a
considerably longer life cycle and are easy to
see even when the light is bad. This increases
road safety, while taking pressure off
community budgets and also off the
environment. In fall 2004, Siemens installed
Germany’s first traffic lights with low-voltage
LEDs in Cologne. The controller is called
SITRAFFIC C840V.
SITRAFFIC C840V –
the power box for all
40 V signal heads has
what it takes and more!
The new controllers are designed for use all over the
world. This means they can cope with all climates
and operating conditions. Glimmering heat or biting
cold, high humidity or even a sandstorm – whatever
the situation, the SITRAFFIC C840V can always be
relied on. The units also have an “inner life” that is
compatible with existing traffic-computer control
centers and ensures harmonious interaction with
other systems from the SITRAFFIC family.
The latest technology:
a 200-MHz PC module in
the SITRAFFIC C840V
enables a linkup to OCIT
control centers
Proven and reliable
Software with the familiar look and feel
The SITRAFFIC C840V has a CPU with a proven
32-bit processor system that controls up to
48 signal groups. The memory can be expanded in stages up to 9.5 megabytes at a
time. States of traffic lights that can cause
a hazard to traffic are ruled out completely
in that fail-safe signal monitoring is performed by two independent microprocessors
(in accordance with VDE 0832).
In the case of the SITRAFFIC C840V as well,
the tools of the SITRAFFIC C800 family are
setting standards for user-oriented software.
Flexible variety, from simple to complex
The SITRAFFIC C840V is suitable for use in
both simple and complex public-transport
priority control systems. The tried-and-tested
4-channel loop detectors of the LD4 series
and also modern video detectors can be
connected without any problems. As an
alternative to connection of a central lamp
switch, the new 40 V LED types of signal
head with PLUS technology are also used
with decentralized lamp switches. For this
purpose, there is the SITRAFFIC C840VP
switching device with modified peripheral
switching elements.
SITRAFFIC CONTROL, the data input
program of the C800V, is based on a
uniform concept with a modern look and
feel for all known functions.
SITRAFFIC SERVICE provides testing tools
for operator control, testing and fault
diagnostics and offers all functional
levels – from fully graphics-based visualization to detailed expert information.
SITRAFFIC LANGUAGE (TL) helps the
operator to solve traffic control problems.
Structograms or flowcharts can be used to
convert traffic control tasks into a program
code without the necessity of possessing
a great deal of programming knowledge.
Library modules contain ready-made
solutions for many different traffic
problems.
PDM/TL control model: With this freely
programmable and stage-oriented model,
control problems can be solved individually – and comprehensive knowledge of
programming languages is not required.
Parameterizable traffic-control function
libraries provide assistance in this respect.
Parameterization instead
of programming. The
software tools of the
SITRAFFIC C840V help
the user to quickly find
the optimum control
solution.
VA component: S-X. This tool can be used
to rationally implement traffic-control
functions with public-transport priorities
based on stage-oriented planning stipulations. The key performance characteristic
of S-X is a standardized control procedure
for whose individual functions prototypes
have been specified. The user takes advantage of the predefined framework and
is spared the time-consuming selection of
the individual modules needed and the
preparation of a logical sequence concept.
Standardized method: S-L. This can be used
to implement functions to match stageoriented planning stipulations. The logical
sequence of the traffic control functions is
predefined, whereas adaptation to the
respective intersection-specific requirements is performed solely by means of
parameterization.
SIEMENS VS PLUS: This software package
contains a standardized, parameterizable
control method. It offers the advantages
provided by a traffic-actuated controller
without therefore having to create a conventional user program.

The new and the

harmony – a comparison
of the SITRAFFIC C840V
and the C800V
For the user, new technologies are often associated
with a lot of extra work and expense. Not so with
the SITRAFFIC C840V traffic controllers. In spite of
their pioneering 40-volt technology, we have
intentionally relied on the same tools, programming
languages and handling details which already
characterize the whole C800 family. In the tables on
this double page spread, we show the differences
between the devices and what they have in common.
