MITSUBISHI A3NCPUP21 Fundamentals Manual A3NCPUP21 Programming Manual

Output type: transistor output, drain type.
Output points: 16 points.
OFF leakage current: 0.1mA.
Output protection function: No.
Rated load voltage / current: DC12V/DC24V/0.5A.
External connection: 2 wire.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup A3NCPUP21 Fundamentals Manual A3NCPUP21 Programming Manual A3NCPUP21
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool. Input: AC100 ~ 120v/200 ~ 240v,
Output: 5A DC5V.
PLC programming has a wide range of applications, powerful, easy to use, has become one of the main devices of modern industrial automation,
In all areas of industrial production has been widely used,
Applications in other areas (such as civil and home automation) have also been rapidly developed A3NCPUP21 Fundamentals Manual A3NCPUP21 Programming Manual.
It uses programmable memory,
An instruction used to perform logical operations, sequence control, timing, counting and arithmetic operations in its internal storage,
And through digital, analog input and output,
Control of various types of machinery or production processes A3NCPUP21 Fundamentals Manual A3NCPUP21 Programming Manual. Programmable controller and related equipment,
Should be easy to make the industrial control system to form a whole, easy to expand the principle design of its functions.
As can be seen from the above definition, PLC is a program to change the control function of the industrial control computer,
In addition to the completion of a wide variety of control functions, as well as with other computer communications networking features. 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 and a photoelectric transistor.
Light emitting diode two: the input of a photo couplerr and the change of electrical signal,
The light signal is generated by the light emitting diode, which is the same as the input signal A3NCPUP21 Fundamentals Manual A3NCPUP21 Programming Manual.
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 A3NCPUP21 Fundamentals Manual A3NCPUP21 Programming Manual.
