Input voltage range: DC24V.
Output voltage: DC5V.
Output current: 2.5A.
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 AJ35PJ-8R Manual AJ35PJ-8R User's Manual AJ35PJ-8R
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 AJ35PJ-8R Manual AJ35PJ-8R User's 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 AJ35PJ-8R Manual AJ35PJ-8R User's Manual.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action. A1SD51S is an intelligent communication module used in ANS series,
Can use the AD51H-BASIC language to make online or offline programming on the universal terminal or computer,
Multitasking can also be performed with up to two programs at high speed.
PLC is the use of " sequential scanning, and constantly circulating " way to work.
That is, in the operation of CPU, PLC according to the user according to the control requirements of the coexistence of the user in the memory of the program,
According to the instruction sequence number (or address number) for periodic cyclic scan, such as no jump instruction,
From the first instruction to the user program execution sequence one by one, until the end of the program,
And then return to the first command, start the next round of the new scan, in the process of each scan,
Also complete the sampling of the input signal and the output status of the refresh and other work.
