SRAM+E2PROM memory card.
RAM capacity: 512KB.
E2PROM capacity: 512KB. Input: 4 channels.
Platinum resistance (Pt100; JPt100).
Heater disconnection detection function.
Sampling period: 0.5s/4 channel.
18 point terminal table x2.
Can be flexible in various settings, to achieve the best temperature control of the temperature control module Q20UDEHCPU Strctured Programming Manual.
Equipment for high temperature control stability of extrusion molding machine,
The temperature regulating module has the function of preventing overheating and preventing over cooling Q20UDEHCPU
According to the control object device, select the standard control (heating or cooling) or the heating and cooling control (heating and cooling) mode.
In addition, the mixed control mode (combined with the standard control and heating - cooling control) can be selected Q20UDEHCPU Strctured Programming Manual.
Peak current suppression.
Can prevent the simultaneous opening of the output to control the peak current, which is helpful for saving energy and reducing the operation cost.
Heating function at the same time.
The multiple loop can reach the set value at the same time to carry out the uniform temperature control,
Helps to prevent no-load and effective energy saving and reduce operating costs Q20UDEHCPU Strctured Programming Manual.
Automatic adjustment function.
The PID constant can be adjusted automatically in the control process.
Automatic adjustment of cost (time, material and electrical energy) can be reduced. Input and output points: 4096 points.
Input / output data points: 8192 points.
Program capacity: 124k.
Basic command processing speed (LD command) S:0.075.
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 meeasure of how much the user application can store the number of indicators Q20UDEHCPU 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 Q20UDEHCPU Manual. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
