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 A953GOT-SBD Extended/Option Functions Manual Manual A953GOT-SBD Operating Manual A953GOT-SBD
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 A953GOT-SBD Extended/Option Functions Manual Manual A953GOT-SBD 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 A953GOT-SBD Extended/Option Functions Manual Manual A953GOT-SBD Operating Manual.
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. The main unit of the AS-i system
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on.
This phenomenon is called the I/O delay time effect.
Input status and input infformation input from the input interface,
CPU will be stored in the working data memory or in the input image register A953GOT-SBD Extended/Option Functions Manual Manual A953GOT-SBD Operating Manual.
And then combine the data and the program with CCPU A953GOT-SBD Extended/Option Functions Manual Manual A953GOT-SBD Operating Manual.
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.
