Input channel number: 2.
Output channel number: 1.
Occupy I/O points: 32.
A1S63ADA analog input / output combination components can be analog / digital / digital / analog conversion,
The input and output signals can be voltage or current,
Offset and gain can be set and stored.
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution time is accounted for the vast majority of A2NCPUP21-S3 Common Instructions Manual A2NCPUP21-S3 Programming Manual A2NCPUP21-S3
The response time of PLC is the interval between the time of the change of the external output signal of the PLC and the time of the change of the external output signal which is controlled by it,
Lag time, this is the time constant of the input circuit,
The time constant of the output circuit, the arrangement of the user statement and the use of the instruction,
The cycle scan mode of PLC and the way of PLC to refresh the I/O and so on A2NCPUP21-S3 Common Instructions Manual A2NCPUP21-S3 Programming Manual .
This phenomenon is called the I/O delay time effect A2NCPUP21-S3 Common Instructions Manual A2NCPUP21-S3 Programming Manual . Enter 64 points.

32 pin connector dynamic input and output data.
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 analog output unit (D/A), in order to transform the digital quantity after PLC processing into analog quantity -- standard electric signal A2NCPUP21-S3 Common Instructions Manual A2NCPUP21-S3 Programming Manual .
So the standard telecommunication number, the conversiion between the number of operations to use a variety of computing A2NCPUP21-S3 Common Instructions Manual A2NCPUP21-S3 Programming Manual .
This requires the resolution of the analog unit and the standard electrical signal.
