RS-232 1 channel.
RS-422/485 1 channel.
Transfer speed: 0.3-19.2kbps.
Input status and input information input from the input interface,
CPU will be stored in the working data memory or in the input image register.
And then combine the data and the program with CPU.
The result is stored in the output image register or the working data memory,
And then output to the output interface, control the external drive A0J2E-E28DT PDF
A0J2E-E28DT
Semiconductor circuit with memory function.

China is the world''s biggest market for human machine interface,
But it is not the highest sales market in the world,
This shows that the low-end user interface in China has a large share of A0J2E-E28DT PDF.
In recent years, the rapid development of national brands, to take a low price and other strategies, is a massive attack on the low end of the market,
Has occupied the dominant position in the low-end market, has won the recognition of the majority of users.
International brands are also gradually developing its economic products, in order to seize the share of the low-end market.
Therefore, in the low-end market steady,
The overall performance of the domestic human machine interface manufacturers showing a rapid growth of the state. TFT color LCD touch screen to replace the backlight.
Applicable models: A975/970GOT-TB_-B, A975/970GOT-TBA, A975/970GOT-TBD. Multi axis positioning controller.
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 and a photoelectric transistor.
Light emitting ddiode 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 A0J2E-E28DT datasheet.
The working process of the input interface circuit: when 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-E28DT datasheet.
