5 slots.
Can be installed in the power supply unit for A series units installed QnA/.
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 A1SJ71C24-PRF Manual A1SJ71C24-PRF User's Manual.
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 A1SJ71C24-PRF
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action A1SJ71C24-PRF Manual A1SJ71C24-PRF User's 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 A1SJ71C24-PRF Manual A1SJ71C24-PRF User's 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. Input type: DC input, positive common end.
Input points: 16 points.
Enter the response time: 0.2ms the following.
Rated input voltage / current: DC24V/5mA.
Output form: transistor output, leakage type.
Output points: 16 points.
OFF leakage current: 0.1mA.
Output protection function.
Rated load voltage / current: DC24V/0.1A.
External connection: 1 line /1 line type.
40 pin connector type (FCN connector type).
Through the 40 pin connector type (FCN connector type) can be connected to a variety of devices.
Can be installed along the 6 direction.
Hardware simulation method is to use a number of hardware equipment to simulate the generation of the signal,
The signals are connected to the input end of the PLC system in a hard wired way, and the timeliness is strong.
Softwaare simulation method is in the MITSUBISHI PLC in the preparation of a set of simulation program,
The simulation provides the field signal, which is simple and easy to operate, but it is not easy too guarantee the timeliness A1SJ71C24-PRF Manual A1SJ71C24-PRF User's Manual A1SJ71C24-PRF Manual A1SJ71C24-PRF User's Manual.
Simulation of the process of debugging, debugging method can be used to segment, and the monitoring function of programmer.
