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 A970GOT-SBA SW4D5C-GOTR-PACKE compatible Connection System Manual Manual A970GOT-SBA User's Manual.
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 A970GOT-SBA SW4D5C-GOTR-PACKE compatible Connection System Manual Manual A970GOT-SBA User's Manual. .
At the same time, there is also an analog input unit (A/D),
Transform these standard electrical signals into digital signals,
The analog output unit (D/A), in order to transform the digital quantity after PLC processing into analog quantity -- standard electric signal.
So the standard telecommunication number, the conversion between the number of operations to use a variety of computing.
This requires the resolution of the analog unit and the standard electrical signal. 5 slots.
Can be installed in the power supply unit for A series units installed QnA/.
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 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.
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,
Generallly an input / output element to take up an input / output point A970GOT-SBA SW4D5C-GOTR-PACKE compatible Connection System Manual Manual A970GOT-SBA User's Manual.
Taking into account the future adjustment and expansion,
In general should be estimaated on the total number of points plus the amount of spare 20%~30% A970GOT-SBA SW4D5C-GOTR-PACKE compatible Connection System Manual Manual A970GOT-SBA User's Manual.
The following describes the centralized control system I/O points of the estimate.
