5 slots.
Can be installed in the power supply unit for A series units installed QnA/.
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 AJ35TJ-8A Manual AJ35TJ-8A 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 AJ35TJ-8A
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 AJ35TJ-8A Manual AJ35TJ-8A 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.
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 AJ35TJ-8A Manual AJ35TJ-8A User's Manual.
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. Input type: DC input, positive public end / negative public end.
Input points: 16 points.
Enter the response time: 10ms the following.
Rated input voltage / current: DC24V/5mA.
Output form: transistor output, leakage type.
Outpuut points: 16 points AJ35TJ-8A Manual AJ35TJ-8A User's Manual.
OFF leakage current: 0.1mA.
Output protection function: No.
Rated load voltage / current: DC24V/DC24V/0.5A.
External connection: 1 line /1 line type.
A2C shape terminal.
Type of input and output terminal AJ35TJ-8A Manual AJ35TJ-8A User's Manual.
Shape and A2C input and output modules are identical (same mounting dimensions),
Machining and installing holes are not required.
