Dear Sir,

I have the requirement of Touch screen in large quantity hence I request you to kindly send the quotation for product you are manufacturing hence I am sending the specification for it.
The requirements of the HMI without PLC are listed below:-

1.The ambient temperature is 60 °C.

2.The screen should be touch sensitive

3.At least 256 colours

4.A front end software to download the images from windows operating system(PC) to the

touch panel.This software should also enable us to download and change new images in to

the panel.

5.The most important is serial communication port RS232 to interface with our control

board which supports modbus protocol and also a USB port.

6.We should be able to download not only the photo images but also flash images or

dynamic images.

7.In built Real Time Clock.

8.2MB internal memory and may be expandble in future.

9.A flash memory card should be insertable.

9.The depth of the panel should not be more which will be inconvenient to place in our
machine.
