The PWM to voltage module LC-LM358-PWM2V can convert PWM digital signals into 0 to 10V analog signals. Can be used for signal interface switching of PLC or other industrial control boards. The output voltage is adjusted by adjusting the duty cycle of the PWM. The module size is small and easy to apply in different places

VCC: Working power 12V-30V
GND: Working power source
PWM: Input PWM signal positive end
GND: Negative end of input signal
VOUT: Output voltage 0-10V
GND: Output voltage ground
Operating instructions: After power-on, when there is no input signal, the output is 0V, and only when there is input can there be output. When powering on for the first time, it is better to do a calibration and debugging: find a signal with 50% duty ratio to connect to PWM,GND, and the amplitude corresponds to the relative jump needle. The frequency is 1KHZ-3KHZ, and the two ports of VOUT and GND are measured with a multimeter. At this time, the meter is displayed at about 5V. Adjust the potentiometer on the board to make the multimeter display at 5.00V. This calibrates the correspondence between your pulse signal and this module. When the frequency changes, the correspondence may shift and need to be recalibrated
The output voltage can be adjusted by adjusting the duty cycle
The accuracy can be controlled by adjusting the potentiometer.
