Input type: DC input, positive public end / negative public end.
Input points: 16 points.
Enter the response time: 10ms the following.
Rated input voltage / current: DC24V/7mA.
External connection: 2 wire.
Type of input and output terminal.
Using 2 pieces of structure of the terminal units, maintenance can be maintained in the same line under the condition of the replacement module AX81-S3 . Multi axis positioning controller
AX81-S3
Program capacity: Max 60K step.
Input / output points: 1920 points.
The length of time required to execute the instruction, the length of the user''s program, the type of instruction, and the speed of the CPU execution are very significant,
Generally, a scanning process, the fault diagnosis time,
Communication time, input sampling and output refresh time is less,
The execution time is accounted for the vast majority of AX81-S3 .
The photoelectric coupler is composed of two luminous two extreme tubes and a photoelectric transistor.
Light emitting diode two: the input of a photo coupler and the change of electrical signal,
The light signal is generated by the light emitting diode, which is the same as the input signal AX81-S3 .
The working process of the input interface circuit: when the switch is closed, the diode light,
The transistor is then guided to the internal circuit and input signal under the irradiation of the light.
When the switch is off, the diode does not emit light, and the transistor is not on the way. Internal circuit input signal.
It is through the input interface circuit to the external switch signal into PLC internal can accept the digital signal.
Photoelectric three levels: in the light of the light signal conduction, the degree of light signal and the intensity of the light signal.
The output signal has a linear relationship with the input signal in the linear operating region of the photoelectric coupler.
User program storage capacity: it is a measurre of how much the user application can store the number of indicators AX81-S3 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 AX81-S3 User's Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
