Insulation blocking, makes the contact for there was only light between each circuit, without electrical connection.
In control signal input module part, the current signal of the 0mA to 20mA of outside input is changed through AD654 chips
For frequency signal.This frequency signal has been input in photoelectrical coupler TLP2166A as input signal, the SPEED letters of output
Number it is sent in chip.Schmidt trigger is carried in TLP2166A.Schmidt trigger and common gate circuit only one of which threshold
Threshold voltage voltage is different, and it has two threshold voltages.This circuit is the one kind in threshold switch circuit, can prevent due to
The change of input voltage is so as to causing the change of output voltage.Electricity is exported when input voltage reaches an assigned voltage value
Pressure is undergone mutation, and changes delayed phenomenon so as to there is output voltage, thus it is recognised that Schmidt trigger is especially fitted
For the certain start-up circuit for postponing of that requirement.We generally can be being sent out after transmission from the rectangular pulse that sensor is obtained
Raw distortion.When capacity ratio on transmission line is larger, it has been found that the rising edge of waveform is significantly slowed down[6]；Because pulse signal
Affect to produce noise；When above-mentioned several phenomenons and problem is run into, we can be anti-phase using Schmidt well
Trigger shaping and obtain more satisfactory rectangular pulse waveform.
