PWM to Voltage Converter Module 0%-100% to 0-10V Digital to Analog PLC

Description:
The 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.

Features:
MCU embedded technology
Easy to operate, fine tuned by potentiometer
Select the PWM signal input level range through short-circuit
The module is smaller, easy to carry and use

Parameter:
Work Voltage:DC 12V-30V; (> 100MA)
PWM Receiver Frequency:1KHZ-3KHZ
PWM signal input level range:

The peak of 4.5V to 10V level. The short cap install in ‘5V’. This level is used for normal controller or 5V MCU
The peak of 12V to 24V level, so inserted in 24V. The short cap install in ‘24V’. This level is used for normal PLC controller
Conversion range:0%-100% PWM to 0-10V
Allowable error:5%


Hardware Interface:
VCC -> DC 12V-30V
GND -> Ground

PWM -> Positive of PWM input signal
GND -> Negative of input signal

VOUT -> Output Voltage 0-10V
GND -> Output Voltage Ground

Operation instructions:
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.
