#1	05V010V Voltage PWM Converter This module can convert 05V or 010V analog input voltage into 0100 PWM signal
#2	Analog Voltage to PWM Converter PWM signal frequency range is 2KHZ20KHZ maximum is 20KHZ default minimum is 2KHZ
#3	Voltage to PWM Converter Default function is converting 010V into 0100 2KHZ PWM signal output frequency can be set by adjusting potentiometer as needed
#4	2KHZ20KHZ PWM Signal Converter PWM signal and voltage can be direct ratiopositive phase output or inverse ratio negative phase output
#5	Voltage to PWM Signal Module There are two kinds of PWM signal PNPPWM output and NPNPWM outputthe PNPPWM output is only 5V level NPNPWM output is 5V and 24V level
