Input points: 16 points.
Voltage: DC100/110/125V.
Current: 2mA.
Response time: 20ms.
8 points / a common end.
Positive / negative sharing.
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 MITSUBISHI A1NCPUR21 User's Manual.
Read only memory
A1NCPUR21 Manufacturers use, content can not be changed, power does not disappear.
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 MITSUBISHI A1NCPUR21 User's Manual. Therefore PLC selection,
Under the premise of meeting the control requirements,
Should consider the best performance to price ratio, a reasonable choice of PLC.
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 MITSUBISHI A1NCPUR21 User's Manual.
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 changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay. Number of channels: 4 channels
Sensing method and temperature range: PT100
A1S64TC series component is a kind of temperature controller combined with ANS seriees CPU A1NCPUR21 Manual .
Components with temperature measurement input and built-in PID algorithm control output,
Can be used in a variety of temperature control occasions.
Each component controls up to 4 loops at most.
Thermocouple input or PT100 3 wire temperature sensor input A1NCPUR21 Manual .
Control output switching signal for the output of the transistor.
BW is a signal with broken line detection function.
