The first characteristic of touch screen:
Transparent, it directly affects the visual effect of touch screen.
The problem of transparency is the degree of transparency, infrared technology, touch screen and surface acoustic wave touch screen is separated by a layer of pure glass,
Transparency can be considered a leader, the other touch screen this is a good scrutiny, transparency",
The touch screen industry, is a very broad concept, many touch screen is a multilayer composite film,
It''s not enough to generalize its visual effect with only a little transparency,
It should include at least four characteristics: transparency, color distortion, reflection and clarity, but also,
For example, the degree of reflection, including the degree of specular reflection and diffraction,
But the touch screen surface diffraction reflection has not reached the extent of the CD disk,
For users, these four metrics are basically enough A0J2E-E28AS A0J2E-E28AS. "Special multi axis positioning controller for NSD servo system.
Optical data communication line.
Program capacity: Max 60K step.
Input / output points: 1920 points.
When the switch is off, the diode does not emit light, and the transistor is not on the way. Internal circuit input signal.
It is through the input interface circuit to the external switch signal into PLC internal can accept the digital signal.
Photoelectric three levels: in the light of the light signal conduction, the degree of light signal and the intensity of the light signal.
The output signal has a linear relationship with the input signal in the linear operating region of the photoelectric coupler.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution time is accounted for the vast majority of.
The photoelectric coupler is composed of two luminous two extreme tubes andd a photoelectric transisstor A0J2E-E28AS.
Light emitting diode two: the input of a photo coupler and the change of electrical signal,
The light signal is generated by the light emitting diode, which is the same as the input signal.
The working process of the input interface circuit: whhen the switch is closed, the diode light,
The transistor is then guided to the internal circuit and input signal under the irradiation of the light A0J2E-E28AS.
