MITSUBISHI PLC hardware implementation
Hardware implementation is mainly for the control cabinet and other hardware design and field construction.
Design control cabinet and the operating table and other parts of the electrical wiring diagram and wiring diagram.
Electrical interconnection diagram of each part of the design system A1SJ71ID2-R4 datasheet.
According to the construction drawings of the site wiring, and carry out a detailed inspection A1SJ71ID2-R4
Because the program design and hardware implementation can be carried out at the same time,
So the design cycle of the MITSUBISHI PLC control system can be greatly reduced. Input voltage range: AC100 ~ 120V.
Output voltage: DC24V.
Output current: 0.6A.
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 A1SJ71ID2-R4 datasheet.
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 A1SJ71ID2-R4 datasheet.
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.
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. Axis of control: 1.
A1SD70 is a kind of voltage outpuut type single axis positioning control module,
Equipped with a servo motor can form a closed loop control system of precise positioning A1SJ71ID2-R4 PDF datasheet.
Its fastest positioning speed up to 400Kpps, the location of the 32 bit binary numbeer (with a symbol bit) A1SJ71ID2-R4 PDF datasheet.
Positioning units according to the specific application settings, such as the number of pulses, millimeters, inches or degrees.
