Installation of the power unit can not be used for AnS QnAS/ series units installed.
The popularization and application of PLC programming has been developed rapidly in our country,
It has been widely used in all kinds of mechanical equipment and production process of electrical control devices,
All walks of life have emerged a large number of application of PLC transformation of the results of the equipment A0J2-68AD datasheet PDF catalog A0J2-68AD PDF datasheet A0J2-68AD
Understand the working principle of PLC, have the ability to design, debug and maintain the PLC control system,
Has become the basic requirements of modern industry for electrical technicians and engineering students.
PLC user program is designed according to the control system of the process control requirements,
PLC programming language through the preparation of specifications, in accordance with the actual needs of the use of the function to design A0J2-68AD datasheet PDF catalog A0J2-68AD PDF datasheet.
As long as the user can master some kind of standard programming language,
To be able to use PLC in the control system,
To achieve a variety of automatic control functions. Type of input: DC leakage.

PLC is introduced by the relay control technology after the development of micro processing technology,
Can be easily and reliably used for switching control.
As the analog quantity can be converted into digital quantity, the number of digital quantity is just a number of switching value,
Therefore, after the conversion of analog, PLC can also be reliable for processing control.
Because the continuous production process often has the analog quantity, the analog quantity control is sometimes called process control.
Analog quantity is not electricity, and PLC can only handle digital quantity, quantity of electricity.
All to realize the conversion between them to have the sensor, the analog quantity into a number of power.
If this power is not standard, but also through the transmitter,
The non-standard power into a standard electrical signal, such as 1-5V, 4-20mA, 0-10V, etc..
At the same time, there is also an analog input unit (A/D),
Transform these standard electrical signals into digital signals,
The annalog output unit (D/A), in order to transform the digital quantity after PLC processing into analog quantity -- standard electric signal A0J2-68AD datasheet PDF catalog A0J2-68AD PDF datasheet.
So the standard telecommunication number, the conversiion between the number of operations to use a variety of computing A0J2-68AD datasheet PDF catalog A0J2-68AD PDF datasheet.
This requires the resolution of the analog unit and the standard electrical signal.
