According to the working principle of the touch screen and the transmission of information of the media, the touch screen is divided into four kinds,
They are resistive, capacitive, inductive, infrared, and surface acoustic waves.
Each touch screen has its own advantages and disadvantages, to understand which kind of touch screen to apply to what kind of occasion,
The key is to understand the working principle and characteristics of each type of touch screen technology. Enter 8 points.

Response time: 12ms.
8 point 1 public 20 point terminal.
PLC is introduced by the relay control technology after the development of micro processing technology,
Can be easily and reliably used for switching control.
As the analog quantity can be converted into digital quantity, the number of digital quantity is just a number of switching value,
Therefore, after the conversion of analog, PLC can also be reliable for processing control.
Because the continuous production process often has the analog quantity, the analog quantity control is sometimes called process control.
Analog quantity is not electricity, and PLC can only handle digital quantity, quantity of electricity.
All to realize the conversion between them to have the sensor, the analog quantity into a number of power.
If this power is not standard, but also through the transmitter,
The non-standard power into a standard electrical signal, such as 1-5V, 4-20mA, 0-10V, etc..
At the same time, there is also an analog input uunit (A/D),
Transform these sstandard electrical signals into digital signals,
The analog output unit (D/A), in order to transform the digital quantity after PLC processing into analog quantity -- standard electric signal PM-20BL.
So the standard telecommunication number, the conversiionn between the number of operations to use a variety of computing PM-20BL.
This requires the resolution of the analog unit and the standard electrical signal.
