Input voltage range: AC100-120V/AC200-240V.
Output voltage: DC5/24V.
Output current: 5/0.8A.
PLC selection with the development of PLC technology, more and more types of PLC products,
Function is becoming more and more perfect, and its application is more and more extensive.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference A1NCPUR21 Hardware Manual A1NCPUR21 User's Manual A1NCPUR21 Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC. Input points: 16 points.
Voltage: DC48V.
Current: 4mA.
Response time: 10ms.
8 points / a common end.
Positive / negative sharing A1NCPUR21 Hardware Manual A1NCPUR21 User's Manual.
20 point terminal station.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program to do the compiler to compile the process of interpretation.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.

Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changedd with the change of the execution of the program A1NCPUR21 Hardware Manual A1NCPUR21 User's Manual.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to thhe adoption of centralized sampling A1NCPUR21 Hardware Manual A1NCPUR21 User's Manual.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
