FEEDERS.
24V DC FOR PLC SIGNALS AND SOV OPERATION.
DERIVED THROUGH DC POWER PACKS.
Battery Charger
HT switch board operation is very important and critical for any power distribution. The operation, control and
protection of this system should be highly reliable, accurate and un interrupted.
Hence, these switch boards are operated on DC supply powered by battery bank, backed up by float and boost
battery chargers.

12. VVVF DRIVES
VVVF Drives are used where speed control, torque control
or position control of the driven equipment are required.
There are 52nos VVVF drives installed in each furnace.
Capacity of these drives varies from 10KVA to 1230KVA.
Application of VVVF Drives
Speed Control—Vibro feeders, Conveyors.
Position Control – Rotation and Tilting Drives
Torque Control – Stock Level Indicators,
Cranes, Conveyors
SOFT STARTERS
Soft starters are used achieve smooth starting and
stopping of the equipment. This will also avoid load
fluctuation. Soft starters are used in conveyors, hydraulic
pumps of mud gun & drilling machines etc.

WHY INSTRUMENTATION?
Instrumentation is required to measure the physical variables or parameters which affects the process and control
of these parameters.

14. RTD/THERMOCOUPLE
RADIATION PYAROMETER
Various types used in furnace
Resistance temperature detector (RTD)
RTD ’s are used for temperature measurement up to
200Deg C.
‘K’ TYPE THERMOCOUPLE
‘K’ type thermocouples are used for the
temperature measurement between 200 Deg to 900 Deg c
‘S’ TYPE THERMOCOUPLE
‘S’ type thermocouples are used for the
temperature measurement between 900 Deg C to 1400
Deg c. Mainly used in stove dome and hot blast line
RADIATION PYROMETERS
Pyrometers are non contact type sensors used for high
temperature measurement from 600 to 1600 Deg C.
All these sensors are connected through smart temperature
transmitter

Major Components of a Common PLC
PLC OVERVIEW

19. RIO PANEL
• The remote input/output panel consists
1.Digital input cards
2.Digital output cards
3.Analog input card
4.Analog output card
5.Interface module
All the signals form the field instruments/ equipments are
measured by these cards are transferred to the interface
module.
• The interface module is the communication link between
I/O cards and PLC which communicates through either
optical fiber cable or twisted pair cable
• Interface module uses special communication protocol
for communication with PLC designed form the PLC
manufacturer. EX.SIEMENS uses Profibus protocol,
EMERSON uses device net
19.

20. SERVER AND CLIENT AND ENGINEERING
STATION
• Server and client configuration is used when the
system is large and operators are more.
• As the name suggests server is a link between
operator station (client) and PLC. All the requests
generated by the operator from operator station are routed
through the server and results of the requests are stored
in the server. The operator station fetches these results
and displays.
• Another important function of Server is data storage.
(trends data, alarms etc).
• Generally both servers and client are desktop PC
loaded with the GUI software
• Server uses well known high speed Ethernet
communication protocol for communication with PLC and
client
• Engineering station is used to develop logic or
software for PLC and diagnostic services of the PLC,
Server and operator station
