PLC Allen BradleyMicrologix
(Programming Logic Controller)
• Developed to replace relays in the late 1960s
• Costs dropped and became popular by 1980s
• Now used in many industrial designs
• The Hydramatic Division of the General Motors Corporation specified
the design criteria for the first programmable controller in 1968
• Their primary goal :To eliminate the high costs associated with
inflexible, relay-controlled systems.

A digitally operating electronic apparatus which uses a programming memory for the
internal storage of instructions for implementing specific functions such as logic,
sequencing, timing, counting and arithmetic to control through digital or analog
modules, various types of machines or process.

Advantages of PLCs
• Less wiring.
• Wiring between devices and relay contacts are done in the PLC program.
• Easier and faster to make changes.
• Make programming easier and reduce downtime.
• Reliable components make these likely to operate for years before failure.

Areas of Application
• Manufacturing / Machining
• Food Industries
• Metals
• Power
• Mining
• Petrochemical / Chemical
• Cementation

12V D.C GEARED MOTOR
• Motors :maximum power 3.9 W
• Extended speed range :3.6 to 430
rpm
• Gearbox torque rating :0.5 N.m
• High-performance plastic gears

Load cell amplifier for weighing scale
• Serial Output Model: 1190
• The board is total solution for analog front end
for Load Cell applications.
• A load cell is a transducer that is used to
convert a force into electrical signal.
• The most common use of this sensor is in
weighing machine.
• Every weighing machine which shows weight
has a load cell as sensing element.

• The output can be used to connect to process indicator for
further display and processing or can be fed to pc serial port
to view on terminal.
• The calibration functions in built in the board giving very
accurate, stable and reliable output every time.

ADVANTAGES
• Automation plays an increasingly important role in the world economy. One
of the important applications of automation is in the automatic weighing
and batching application for food industries and cement factory.
• Reduced the human operators
• More profit
• More accurate
• Less time
• Increase the efficiency

APPLICATION
• Totally Integrated Automation puts this continuity into consistent practice. Totally
Integrated Automation covers the complete production line, from receipt of goods,
the production process, filling and packaging, to shipment of goods.
• One of the important applications of automation is in the automatic weighing and
batching application for food industries and cement factory
• Our project is also an application of automation wherein we have developed a liquid
filling to bottles of different height. The various processes are controlled using a
PLC (Programmable Logic Controller).
