TECHNOLOGIES WHICH ARE USED..

• PLC

•MICROCONTROLLERS

•INFARED SENSING

•ULTRASONIC SENSING

COMPONENT WHICH ARE USED..

• RELAY

• OPTO COUPLER

• TRANSISTER

• DRIVES

• RESISTORS

• MOTION SENSOR

• IR RECEIVER

• STEPPER MOTOR

SIMATIC CONTROLLER PLC (S7-300)

• MODULAR SMALLER CONTROLER SYSTEM.

• PERFORMANCE GRADED RANGE OF CPU.

• EXTENSIVE SELECTION OF MODULES.

• EXPANDABLE DESIGN WITH UP TO 32 MODULES.

• PLC IS USED 24V.

GENERATING A HARDWARE SETPOINT CONFIGURATION

MICROCONTROLLERS

• IT IS USED IN AUTOMATICALLY CONTROLLED PRODUCTS & DEVICES.

• A MICROCONTROLLER IS A SMALL COMPUTER ON A SINGLE INTERGRATED CIRCUIT.

• REDUCING THE SIZE & COST.

• MICROCONTROLLERS MAKE IT ECONOMICAL TO DIGITALY CONTROL EVEN MORE DEVICE & PROCESS.

MICROCONTROLLERS

•ADINO

•PIC

INFARED SENSOR

• IT IS AN ELECTRONIC SENSOR THAT MEASURES INFARED LIGHT .

• IT IS TWO TYPES

IR TRANSMITER.

IR RECEIVER.

ULTRASONIC SENSOR (HC-SR04)

• IT IS SIMILAR WORK ON PRINCIPLE RADAR AND SONAR.

• WHICH IS EVALUATE ATTRIBUTES OF A TARGET BY INTERPRETING THE ECHOS RADIO OR SOUND ECHOS

WAVES RESPECTIVELY.

• ACTIVE ULTRASONIC GENERATE HIGH FREQUENCY SOUND WAVES & EVALUATE THE ECHO WHICH IS

RECEIVED BACK BY THE SENSOR.

• RELATIVELY LARGE RANGE.

• OUTDOOR APPLICATION POSSIBLE.

RELAY

• A RELAY IS AN ELECTRICITY OPERATED SWITCH.

• MANY RELAYS USE AN ELECTROMAGNET TO OPERATE A SWICHING MECHANISM.

RELAY CONSTRUCTION.

• ELECTROMAGNENT.

• ARAMATURE THAT CANBE ATTRACTED BY THE ELECTROMAGNENT.

• SPRING.

• SWITCHING CONTACTS.

RELAY TERMINALS

•RELAY IS USED 4 TERMINALS.

85-COIL GROUND.

86-COIL BATTERY.

87-NORMALLY OPEN.

87A-NORMALLY CLOSED.

OPTOCUPLER

• OPTOCUPERS ARE DESINGNED TO PROVIDE COMPLETE ELECTRICAL ISOLATION BETWEEN AN I/P &O/P

CIRCUITS.

• AN OPTO ISOLATOR CONTAINS A SOURE OF LIGHT ,ALMOST ALWAYS A NEAR INFRARED LIGHT –EMITTING

DIODE.

• PROVIDE PROTECTION FROM HIGH VOLTAGE ,SURGE VOLTAGE & LOW LEVEL NOISES .

FOUR TYPE OF OPTOCUPLER

• LED TRANSISTOR.

• LED THYRISTOR.

• LED TRIAC.

• LED DARLNGTON.

WE ARE USED LED TRANSISTOR.

STEPER MOTOR

• PERMANET MAGNET MOTOR.

• VARIABLE REACTANCE MOTOR.

• IT HAS LIMITED TORQUE.

• IT IS LOW SPEED APPLICATION.

• IT IS CONTROLLED BY DRIVERS.

TRANSISTORS

• IT IS SEMICONDUCTOR DEVICE.

• MORE TYPES OF TRANSITOR.

• TRANSISTOR COMMONLY USED AS ELECTRONIC SWITCHES.

• HIGH-POWER APPLICAIONS SUCH AS SWITCHED MODE POWER SUPPLIES.

• TRANSISTOR AS AN AMPLIFIER.
