he PWM transfer voltage module LC-LM358-PWM2V converts the PWM digital signals
into 0 to 10V analog signals.
It can be used as signal interface switching for PLC or other industrial control boards. The output voltage is regulated by adjusting the duty ratio of the PWM. The modules are small in size and easy to use in different places.
Using single chip embedded technology;
Peak 4.5v to 10V level, jumper inserted at 5V. This level of signal mainly for conventional industrial control card (such as MACH3 board Card) 5V CPU interface;
Easy to operate, can be fine-tuned by potentiometer;
Select the PWM signal input level range through short cap;
Module is small, easy to carry and use;
Module operating voltage: DC12V-30V (power requirements: greater than 100mA);
PWM signal reception frequency range: 1KHz-3KHz;
Peak 12 to 24V level, jumper inserted in the 24V. This level of signal is mainly aimed at the conventional PLC interface;
Conversion range: 0% -100% PWM to 0-10v voltage;
Allowable error: 5%;

VCC: working power 12-30V
PWM: input PWM signal positive
GND: input voltage ground
VOUT: Output voltage: 0-10V
GND: output ground
After power on, without input signal, the output is 0V, so only input can output.
The first time when the power is on, it is best to do a calibration debugging:Input a 50% duty ratio signal to PWM/GND and adjust the relative amplitude short cap. The frequency is 1KHZ-3KHZ, Measured VOUT and GND with a multimeter and it will display 5V. Adjust potentiometer to make sure display 5.00V on multimeter. This will calibrate your pulse signal to this module.
When the frequency changes, the correspondences may be offset and need to be re calibrated.
The output voltage can be adjusted by adjusting the duty ratio.
The accuracy can be controlled by adjusting the potentiometer.
