8 slots.
The main substrate needs to be equipped with CPU and power supply.
Requires 1 power modules.
Used to install Q series modules.
A variety of modules with excellent performance,
Meet the needs of various control from analog to location.
Q series module products include a variety of types of I/O, analog and positioning function module Q172LX PDF.
Can fully meet the switch, sensor, such as the input and output, temperature, weight, flow and motor, drive control,
As well as the requirements of high-precision control of the positioning of the industry, the control needs of various fields Q172LX
Can also be used in combination with the CPU module to achieve appropriate control.Input and output points: 2048 points Q172LX PDF.
Input / output data points: 8192 points.
Program capacity: 92k.
Basic command processing speed (LD command) S:0.15.
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 Q172LX PDF.
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.
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 mmeasure of how much the user application can store the number of indicators Q172LX datasheet.
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 Q172LX datasheet. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
