MITSUBISHI A1SJ71QLR21 Product information and technical parameters:
Brand: MITSUBISHI
Name: Network module
Model: A1SJ71QLR21
3C-2V/5C-2V coaxial cable between double loop PC (control station / common station) / remote I/O network (remote master station).
Q mode.
When the programmer input programinto the user program memory,
Then CPU according to the function of the system (the system program memory to explain the compiler),
Translate the user program into PLC internally recognized by the user to compile the program.
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.
Semiconductor circuit with memory function.
System program memory and user memory.
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.
User memory: user program storage area and work data storage area.
Composed of random access memory (RAM). User use.

PLC is introduced by the relay control technology after the development of micro processing technology,
Can be easily and reliably used for switching control A1SJ71QLR21
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 MITSUBISHI A1SJ71QLR21.
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 MITSUBISHI A1SJ71QLR21. .
At the same time, there is also an analog input unit (A/D),
Transform these standard 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.
So the standard telecommunication number, the conversion between the number of operations to use a variety of computing.
This requires the resolution of the analog unit and the standard electrical signal. Number of channels: 2 channels.
Sensing method and temperature range: PT100.
A1S64TC series component is a kind of temperature controller combined with ANSS series CPU A1SJ71QLR21.
Components with temperature measurement input and built-in PID algorithm control output, can be used in a variety of temperature control occasions.
Each component controls up to 4 loops at most.
Thermocouple input or PT100 3 wire temperature sensor input A1SJ71QLR21.
Control output switching signal for the output of the transistor.
BW is a signal with broken line detection function.
