Input voltage: AC100 ~ 120V/AC200 ~ 240V.
Output voltage: DC5V.
Output current: 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 A2SHCPU-S1 PDF.
Different series of different models of PLC has different performance, applicable occasions also have different emphasis,
Price also has a greater difference A2SHCPU-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. Input and output points: 2048 points A2SHCPU-S1 PDF.
Input / output data points: 2048 points.
Program capacity: 30K.
Basic command processing speed (LD command) s:0.15.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called thhe host or the basic unit, small, ultra small PLC using this structure A2SHCPU-S1 PDF A2SHCPU-S1 Manual .
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh MITSUBISHI User's Manual.
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 MITSUBISHI User's Manual.
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 User's Manual.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delay.
User program storage capacity: it is a meaasure of how much the user application can store the number of indicators A2SHCPU-S1 User's Manual.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General llogical operation instructions each account for 1 words A2SHCPU-S1 Manual . Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
