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 A1SJCPU-S8 Common Instructions Manual A1SJCPU-S8 Programming Manual A1SJCPU-S8
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%.
The following describes the centralized control system I/O points of the estimate A1SJCPU-S8 Common Instructions Manual A1SJCPU-S8 Programming 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 A1SJCPU-S8 Common Instructions Manual A1SJCPU-S8 Programming Manual .
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action. Series Name: A975GOT.
Size: 10 inches.
Resolution: 600 * 480.
Display equipment: high brightness TFT color display.
Display color: 16 color.
Power supply: DC24V.
Memory card: 1M.
Man machine interface is the interface between man and machine in the field of information exchange and function contact or influence,
Information exchange, functional contact or mutual influence, the hard contact and soft touch of a person and machine,
This interface includes not only the direct contact point line side,
It also includes the function of remote information transmission and control.
The man-machine interface is the central link in the man-machine system,
Mainly from the safety engineering branch of the safety ergonomics to study and put forward the basis for the solution,,
And over the safety engineering equipment engineering, safety management engineering and safety systems engineering to study the specific solutions and measures to the safety of human computer science and technology A1SJCPU-S8 Common Instructions Manual A1SJCPU-S8 Programming Manual A1SJCPU-S8 Common Instructions Manual A1SJCPU-S8 Programming Manual .
It realizes the transformation between the internal form of information and the acceptable form of human being.
