Conversion speed: 10ms/ channel.
18 point terminal station.
Isolation between channels.
Power supply to a two wire transmitter.
The possibility of expanding control with intelligent function.
At the same time, the channel isolation analog module realizes high isolation voltage,
Further improve the accuracy of the benchmark.
Provide support for process control using a general purpose programmable controller Q173NCCPU Application Functions Manual Q173NCCPU Strctured Programming Manual.
Flow meter, pressure meter, other sensors can be directly connected to analog input,
Control valve can also be directly connected to analog output.
Hardware and installation costs have been greatly reduced due to the need for an external isolation amplifier.
High insulation strength.
Can isolate electrical interference, such as current and noise, etc Q173NCCPU Application Functions Manual Q173NCCPU Strctured Programming Manual. .
Standard analog input module.
Isolated analog input module.
No external isolation amplifier required.
Without the use of inter channel isolation analog modules.
Using the inter channel isolation analog module.Input and output points: 2048 points.
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.
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 measure of how much the user application can store the number of indicators Q173NCCPU Application Functions Manual Q173NCCPU Strctured Programming 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 Q173NCCPU Application Functions Manual Q173NCCPU Strctured Programming Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
