A pack of 20.
Applicable models:
AJ65SBTC - - - type remote I/O module.
AJ65VBTCU - - - type remote I/O module.
AJ65VBTCU- - type remote I/O module. Input and output points: 2048 points.
Input / output data points: 2048 points.
Program capacity: 30K.
Basic command processing speed (LD command) s:0.15 A8GT-C300EXSS-1 PDF datasheet.
Coaxial data communication line function.
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 the host or the basic unit, small, ultra small PLC using this structure A8GT-C300EXSS-1
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way A8GT-C300EXSS-1 PDF datasheet. Easy maintenance.
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 A8GT-C300EXSS-1 PDF datasheet.
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.
User program storage capacity: it is a measure of how much the user application can store the number of indicators.
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 logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4. 32 point connector for welding (37 pin D-Sub connector).Output points: 16 points.
Voltage: DC24/48V.
OFF leakage current: 0.1mA.
Output type: transistor output (type sink).
Response time: 3ms.
8 points / a common end.
20 point terminal station.
With short circuit protection.
With the surge absorber.

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. Therefore PLC selection,
Under the premise of meeting the control requiremennts,
Should consider the best performance to price ratio, a reasonable choice of PLC A8GT-C300EXSS-1 PDF catalog.
System program memory for storing system program,
Including management procedures, monitoring procedures, as well as the user program tto do the compiler to compile the process of interpretation A8GT-C300EXSS-1 PDF catalog.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
