A1SCPU-S1 MITSUBISHI A1SCPU-S1

Input points: 32 points.
Input voltage: DC12/24V.
Current: 3/7mA.
Response time: 10ms.
Positive / negative sharing.
50 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 A1SCPU-S1.<
Read only memory. 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 A1SCPU-S1.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference A1SCPU-S1. 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 MITSUBISHI A1SCPU-S1. 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 MITSUBISHI A1SCPU-S1.
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 MITSUBISHI A1SCPU-S1.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay. Output type: transistor output, drain type.
Output points: 8 points.
OFF leakage current: 0.25mA.
Output protection function.
Rated load voltage / current: DC12V/DC24V/0.5A.
External connection: 2 wire.
According to the external connection mode and the external equipment input and output specifications,
Choose from a rich product lineup.
Finger protection through the upper part of the terminal,
The human body will not be exposed to live parts,
Therefore, the terminal station type remote I/O module can be directly mounted to the machine tool.
Program memory capacity: 8k.
Input / output points: maximum 256 points.
A scan cycle of PLC must pass through three stages: input sampling, program execution and output refresh.
PLC in the input sampling phase: first of all, in order to sccan the sequence of all existing input latches in the input terminal of the state or input data read,
And write it into the corresponding input status register,
Refresh the input, then close the input port, enter the program execution stage A1SCPU-S1.
