Rated input voltage / current: DC24V/5mA.
External connection: 1 wire.
A2C shape terminal.
Type of input and output terminal.
Shape and A2C input and output modules are identical (same mounting dimensions),
Machining and installing holes are not required AJ71E71 Manual AJ71E71 User's Manual AJ71E71 Input points: 32 points.

Response time: 10ms.
8 points / a common end.
Negative utility.
38 point terminal station.
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 AJ71E71 Manual AJ71E71 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 AJ71E71 Manual AJ71E71 User's Manual.
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.
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 requirements,
Shouldd consider the best performance to price ratio, a reasonable choice of PLC AJ71E71 Manual AJ71E71 User's Manual.
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 AJ71E71 Manual AJ71E71 User's Manual.
Read only memory. Manufacturers use, content can not be changed, power does not disappear.
