Input type: DC input, positive common end.
Input points: 8 points.
Enter the response time: 0.2ms below, below 1.5ms, 5ms below, 10ms the following.
Rated input voltage / current: DC24V/7mA.
Output form: transistor output, leakage type.
Output points: 8 points.
OFF leakage current: 0.1mA.
Output protection function: No A1SJ71LR21 Reference Manual .
Rated load voltage / current: DC24V/0.5A.
External connection: 3 line /2 line type A1SJ71LR21
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup.
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool A1SJ71LR21 Reference Manual . 2 slots.
Can be installed in the power supply unit for A series units installed QnA/.
Cannot extend.
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 A1SJ71LR21 Reference 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 MITSUBISHI A1SJ71LR21 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 MITSUBISHI A1SJ71LR21 Manual .
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 MITSUBISHI A1SJ71LR21 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 voltage: AC100-240V.
Rated output: DC5V, 3A and DC24V, 0.6A.
The power supply module is connected with the external power supply, and tthe DC5V is provided with the AnS programmable controller,
They are inserted in the slot of the special power supply component on the base board,
The output of the DC5V is powered by the power supply on the substrate to the component A1SJ71LR21 Reference Manual A1SJ71LR21 .
The input voltage of the component is related to the selected model.
A1S61PN/62PN has Deng generation A1S61P/A1S62P, A1S61PEU/A1S62PEU.
