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.
