Input type: AC.
Input points: 16 points.
Input voltage: AC200-240V.
Input current: 11mA.
Connection mode: terminal row.
Common common point: 16.
The instruction list programming language is a programming language similar to assembly language mnemonic,
As well as assembly language by the operation code and the number of operations A975GOT-TBD-B PDF.
In the case of the computer for the PLC handheld programmer compile user program A975GOT-TBD-B
At the same time, the programming language of the instruction list corresponds to the ladder diagram programming language,
In PLC programming software can be converted to each other. Figure 3 is the instruction sheet corresponding to the ladder diagram of figure 2PLC A975GOT-TBD-B PDF.
The characteristics of instruction table programming language is used to represent mnemonic operation function,
Easy to remember, easy to grasp;
In the handheld programmer on the keyboard using the mnemonic representation, easy to operate, can be programmed in computer;
There is a one-to-one correspondence between the ladder diagram and the ladder diagram A975GOT-TBD-B PDF. Its characteristics are basically consistent with the ladder diagram language. Input type: DC input, positive common end.
Input points: 8 points MITSUBISHI Operating Manual.
Enter the response time: 1.5ms the following.
Rated input voltage / current: DC24V/7mA.
Output form: transistor output, leakage type.
Output points: 8 points.
OFF leakage current: 0.25mA.
Output protection function.
Rated load voltage / current: DC24V/0.5A.
External connection: 1 line /1 line type MITSUBISHI Operating Manual.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup.
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 MITSUBISHI Operating Manual. 5 slots.
Can be installed in the power supply unit for A series units installed QnA/.
When the programmer iinput 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 A975GOT-TBD-B Manual.
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 accordinng to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A975GOT-TBD-B Operating Manual.
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% A975GOT-TBD-B Manual.
The following describes the centralized control system I/O points of the estimate.
