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 A975GOT-TBD-B
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 A975GOT-TBD-B Introductory Manual Manual A975GOT-TBD-B Operating Manual.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
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 A975GOT-TBD-B Introductory Manual Manual A975GOT-TBD-B Operating Manual.
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.
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. Available network: 10BASE55 A975GOT-TBD-B Introductory Manual Manual A975GOT-TBD-B Operating Manual.
Max / total distance: 500/2500M.
A1SJ71E71 is a compact Ethernet interface module,
Used to hang ANS series PLC to ethernet.
There are two kinds of hanging network modules: A11SJ71E71-B2-S3 and A1SJ71E71-B5-S3 respectively corresponding to 10BASE2 and 10BASE5,
So that the vast majority of installed cable can continue to use A975GOT-TBD-B Introductory Manual Manual A975GOT-TBD-B Operating Manual.
