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.

Features:

MCU embedded technology

Easy to operate, fine tuned by potentiometer

Select the PWM signal input level range through short-circuit

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.
