Objective

“To minimize Human Effort in washing

a dish”

About Dishwasher

A dishwasher is an electrically operated automated machine used for washing, rinsing and drying the

dishes.

Software:WPL SoftwareProteusAltium

About PLC

Programmable Logic Controller (PLC) is a digitally operating electronic apparatus that uses a programmable memory for internal

storage of instructions for implementing specific functions.

Advantages of PLC over uC

They are Proven Systems to work in Industrial environments

Direct Interoperability to other industrial devices

Very Rigid compared to microcontroller

No Programming background required

PLC used….

Model No- DVP32ES200R

MPU points: 16 / 20 / 24 / 32 / 40 / 60

Program capacity: 16k stepsBuilt-in with 3 COM ports:

1 RS-232 port and 2 RS-485 ports

Built in with 12-bit 4 A-D/2 D-A

Handy instructions for frequency inverter16 Digital Input (24VDC sink/source) / 16 Digital Output

Specifications of Delta DVP-ES2

Formation of a High Pressure Water Jet:

A high pressure pump sucks water and accelerates it strongly.

The accelerated water runs through the pump system and gets to the high pressure nozzle.

And then nozzle produces the high pressure water jet.

Water Jet

Sensing Distance: Up to 1m

Emitter: 1mW red laser diode

Operating Voltage: DC 4.5 VDC - 5.5VDC

Operating Current: 25mA

Response Time: 2ms

Laser Break Beam Sensor

Motor used for Conveyor Belt

Low-Speed Synchronous AC Motor

Motor rotates with speed proportional with the frequency.

Fluctuation in load does not affects the rotation.

Can be driven in both the directions.

Long rated life of 10,000 hours.

Water Level Indicator

Water Level Indicator

There is no conductive path between the indicating probes and the common probe so it remains in cut off region.

Water Level Indicator

There is a conductive path between the indicating probes and the common probe so BJT goes into active region.
