A pack of 10.
Applicable models:
AJ65VBTCE - -8 - type.
AJ65VBTCE - -16 - type. 4 channel analog input module.
A1S64AD analog input module can accept the voltage or current signal,
The built-in microprocessor converts these signals to binary values,
For the control program to enjoy.
Signal can be instantaneous read, can also be programmed time / frequency average,
The offset and gain value can be set, and this component also includes the following performance:
4 input channels AY10A PDF AY10A
High resolution digital output.
Total accuracy plus or minus 1%. MELSECNET (II).
Coaxial circuit. 3C-2V/5C-2V coaxial cable between double loop PC (control station / common station) / remote I/O network (remote master station) AY10A PDF.
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 AY10A PDF.
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.
Power cut off. Commonly used efficient lithium battery as a backup power supply, life is generally 3~5 years. Input voltage range: AC100 ~ 120V.
Output voltage: DC24V.
Output current: 0.6A.
Relay output interface circuit of PLC
Working process: when the internal circuit output digital signal 1,
There is a current flowing through, the relay coil has a current, and then the normally open contact is closed,
Provide load current and voltage.
When the internal circuit outputs a digital signal 0, there is no current flowing through it,
The relay coil does not have a current, and the normally open contact is broken off,
A current or voltage that is disconnected from the load.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
I/O points is an important indicator of PLC.
Reasonable selection of I/O points can not only satisfy the control requirements of the system,
And the total investment of the system is the lowest.
The input and output points and types of PLC should be determined acccording to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point AY10A datasheet.
Taking into account the future adjustment and expansion,
In general should be estimaated on the total number of points plus the amount of spare 20%~30% AY10A datasheet.
The following describes the centralized control system I/O points of the estimate.
