General view of the controller SCS DP0
The controller SCS DP0 is technologically advanced
equipment provided with microprocessor and software which
enables
continuous
supervision
of
operational
parameters of the installed equipment at a site e.g.:
#
APPLICATION:
Information transmission for Supervisory Centre about operating conditions of power supply systems and
air conditioners and continuous monitoring of operating
conditions at sites in :
! telecommunications,
! power engineering,
! industry,
! railway engineering,
etc.
BASIC ADVANTAGES:
" Simplicity of design and operation,
" high accuracy of monitored measurements of analog
quantities (± 1%),
" easy installation and start-up at site,
" not required installation of additional interfaces,
" high reliability because of simple design of the controller
" communication with any Supervisory Centre by means
of transmission protocol KSN IŁ,
" the non-volatile memory guarantying the storing of
events even after the power supply failure of
controller.
" communication possibilities through: switched line,
GSM network, computer network (TCP/IP).

DC power supply systems (e.g. telecommunications
power supply systems),
# AC power supply systems (e.g. inverter systems,
UPSs),
# generating sets,
# air conditioners,
# AC and DC distribution systems, converters etc.
and sending all information as regards operating
conditions and history of events to the Computer Supervisory Centre by means of transmission protocol KSN IŁ.
SCS DP0 can control and measure temperature
(option- humidity) by means of external sensor located
in any place of the supervised equipment.
The controller SCS DP0 enables to take measurements
of analog quantities and control the digital signals sending
signals and alarm messages in case of equipment failure. The
controlled equipment does not have to be equipped with
systems of interfaces allowing the adjustment of signals level
to KSN standard. The non-volatile memory is used for recording
the
history
of
events,
whose
main
advantage is protection and
saving
the last 6
records even in case of power supply failure of the controller
SCS DP0 .
SCS DP0 has been designed and manufactured by
EP&M with using the most advanced electronic
components and own specialized software that guarantees
easy installation and configuration at a site. The high
operation reliability of the controller SCS DP0 is obtained
by simplifying in great majority its design in relation to
similar equipment existing on market.

Technical features
Design of SCS DP0
The integral component of controller is an
internal telephone modem. The controller communicates with the Supervisory Centre by means
of telephone line. In case of lack of possibilities
as regards connection to the switched telephone
line, optionally, the controller can be equipped
with the external modem GSM. The
sockets for external connection are located at the
back part of controller.
The signal input from current shunt of the supervised equipment is used for current measurement.
Optionally, the current measurement can be
realized by means of the external Hall sensor.
The temperature is measured by external
semiconductor temperature sensor.
The external alarms are provided in a form of
power supply ,,+”. After power supply failure of
the controller SCS DP0, the last six records are
stored in the non-volatile memory and after
voltage recovery the user receives full view
of equipment operation before occurrence of
power supply failure.
Each message includes full information about
state of the supervised equipment (measured values
and alarm states) and date and real time of starting
and finishing an event.
By means of push buttons to be placed on the front
plate of the controller SCS DP0, the current state
of the supervised equipment can be seen on the
lighted liquid crystal display and the configuration
of controller can be changed after entering the
password.
FUNCTIONS OF CONTROLLER SCS DP0 :
! Measurement in real time of voltage, current
and temperature,
! Operation in real time - maximum 8 external
digital quantities,
! Immediate sending of signals and alarm
messages about operating conditions of the
monitored equipment to the Supervisory
Centre,
! Communication with any Supervisory Centre
by means of transmission protocol of KSN IŁ
system,
! Configuration of the controller is performed
directly at a site by means of push buttons
located on the front plate.
! Record of information in the non- volatile
