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 according to the analog quantity and switch quantity of the controlled object,
Generally an input / output element to take up an input / output point A0J2D71 datasheet PDF catalog A0J2D71 PDF datasheet A0J2D71
Taking into account the future adjustment and expansion,
In general should be estimated on the total number of points plus the amount of spare 20%~30%.
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 A0J2D71 datasheet PDF catalog A0J2D71 PDF datasheet.
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 A0J2D71 datasheet PDF catalog A0J2D71 PDF datasheet.
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. Output type: transistor output, drain type.
Output points: 8 points.
OFF leakage current: 0.1mA.
Output protection function.
Rated load voltage / current: DC24V/DC24V/0.1A.
External connection: 2 wire.
Sensor connector type (E-CON type).
Using industry standard E-CON type.
Simple wiring through sensor connector.
When installing the module can choose to use the DIN guide rail or screw mounting.
3 wire sensor input. 16 channels.
Input (resolution): -4000 ~ 4000.
Output: DC-5 ~ 5V, DC10 ~ 10.
Conversion speed: 0.5ms * channel number +2ms.
38 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 produuct in the production of MITSUBISHI motor in Dalian A0J2D71 datasheet PDF catalog A0J2D71 PDF datasheet.
It uses a kind of programmable memory for its internal storage procedures,
Execute logic operation, sequence control, timing, counting and arithhmetic operations, user oriented instruction,
And through digital or analog input / output control of various types of machinery or production process A0J2D71 datasheet PDF catalog A0J2D71 PDF datasheet.
