How to choose MITSUBISHI PLC.
MITSUBISHI PLC options include the choice of MITSUBISHI PLC models, capacity, I/O module, power, etc..
MITSUBISHI PLC distribution I/O points and design MITSUBISHI PLC peripheral hardware circuit
Draw the I/O point of the PLC and the input / output device connection diagram or the corresponding table,
This part also can be carried out in second steps MITSUBISHI Relay output module PDF datasheet A1SY18A
Design PLC peripheral hardware circuit.
Draw the electrical wiring diagram of the other parts of the system,
Including the main circuit and the control circuit does not enter the PLC, etc MITSUBISHI Relay output module PDF datasheet. .
The electrical schematic diagram of the system composed of I/O PLC connection diagram and PLC peripheral electrical circuit diagram.
So far the system''s hardware electrical circuit has been determined. Input voltage range: DC24V.
Output voltage: DC5V.
Output current: 2.5A.
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 MITSUBISHI Relay output module PDF datasheet.
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 A1SY18A PDF datasheet.
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% A1SY18A PDF datasheet.
The following describes the centralized control system I/O points of the estimate.
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 A1SY18A PDF datasheet.
When the innternal 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 discoonnected from the load MITSUBISHI Relay output module PDF datasheet A1SY18A PDF catalog.
It is through the output interface circuit to the internal digital circuit into a signal to make the load action or not action.
