Spring clamping terminal platform push type input module A3ACPUP21-S1 Common Instructions Manual A3ACPUP21-S1 Programming Manual A3ACPUP21-S1
Input module with diagnostic function
The use of push type, do not need screw fastening, so can reduce the wiring hours.
Can be used for each 1 points to enter the wiring of the broken wire detection.
Wiring abnormality of external power supply can be confirmed.
Using 2 pieces of structure of the terminal units, maintenance can be maintained in the same line under the condition of the replacement module A3ACPUP21-S1 Common Instructions Manual A3ACPUP21-S1 Programming Manual . 8 slots.
Power supply unit.
QnAS series unit installation.
High speed access.
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 A3ACPUP21-S1 Common Instructions Manual A3ACPUP21-S1 Programming 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%.
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.
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 diigital 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 discoonnected from the load A3ACPUP21-S1 Common Instructions Manual A3ACPUP21-S1 Programming Manual A3ACPUP21-S1 Common Instructions Manual A3ACPUP21-S1 Programming Manual .
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
