MITSUBISHI QA1S51B Product information and technical parameters:
Brand: MITSUBISHI
Name: Old small A series expansion substrate
Model: QA1S51B
1 slots; no power supply; used to install large PLC series AnS module.
Base plate of AnS series PLC.
QA1S series PLC 1 slot main substrate.
AnS series of modules can be installed.

I/O slots: 2 slots.
Can you install the power module.
Outline dimension: 155*130.
There are two types of extended floor,
A power module can be inserted, and the other one is not.
The choice of any type of substrate depends on the total DC5V current consumption and the power supply on the CPU main substrate QA1S51B.
If the total demand is less than the power output, no additional power supply,
Then you can choose a more economical expansion board QA1S51B
Both ends of the main base plate of the CPU have an expansion interface, and can be used for extending the cable connection. 3C-2V/5C-2V coaxial cable single bus remote I/O network (remote I/O 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 QA1S51B.
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 QA1S51B.
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 (RRAM) QA1S51B. User use.
Power cut off. Commonly used efficient lithium battery as a backup power supply, life is generally 3~5 years. Cable length: 0.055 meters.
Extending cable to connect CPU main substrate and extended substrate,
According to the model can provide different cable length,
If you need to connect the AnN type expansion substrate is required,
Selection of A1SC05NB (A1SC07NB) cable QA1S51B.
