MITSUBISHI A0J2-D61S1 Product information and technical parameters： Brand:
Name: Analog output module
Count input signal: DC5/12/24V, 2-5mA.
External input: DC5V/DC12V/DC24V.
External output: Transistor (open collector) DC12/24V, 0.5A.
36 point terminal station.
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.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
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.
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.
MITSUBISHI PLC is the main product in the production of MITSUBISHI motor in Dalian.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process.
To install the power supply.
For QnA/A series.
Switch volume control is designed to,
According to the current input combination of the switch quantity and the history of the input sequence,
So that PLC generates the corresponding switching output,
In order to make the system work in a certain order MITSUBISHI A0J2-D61S1.
So, sometimes also known as the order control.
And sequential control is divided into manual, semi-automatic or automatic A0J2-D61S1
And the control principle is decentralized, centralized and hybrid control three.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read MITSUBISHI A0J2-D61S1.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions MITSUBISHI A0J2-D61S1.
Time of instruction.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear. Coaxial data link anomaly station.
Extension sub station.
Redundant operation switch of master station. Special multi axis positioning controller for NSD servo system.
Program capacity: Max 60K step.
Input / output points: 1920 points.
Control AC motor required I/O points with PLC control AC motor,
Signal and feedback signal is used as the input signal of PLC,
The control of AC motor is accomplished by using the output signal of PLC to drive the contactor.
For example, the AC motor is controlled by a Y- delta starting with PLC,
Generally need to occupy 4 of the PLC input and 3 output points,
PLC control of a one-way operation of the cage type motor,
4 input points and 1 output points are occupied, and a reversible motor is coontrolled,
5 input points and 2 output points are needed to control a unidirectional operation of variable pole speed control motor,
5 input points and 2 output points are required to control a unidirectional operation of the rotor AC mottor,
3 input points and 4 output points are needed to control a reversible running winding rotor AC motor,
Requires 4 input points and 5 output points A0J2-D61S1 A0J2-D61S1.
