The PWM transfer voltage module LC-LM358-PWM2V converts the 0 to 10V analog signals into digital PWM 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 module is manufactured using MCU embedded technology making the module small in size and easy to use.

Features:

• MCU embedded technology
• Easy to operate, fine tuned by potentiometer
• Selection of the PWM signal input level range through short-circuit

Parameters:

• Module working voltage: DC 12V-30V; (current greater than 100mA)
• PWM signal receiving frequency range: 1KHz-3KHz
• PWM signal input level range: The peak-to-peak value is 4.5V to 10V, and the jumper cap is inserted at 5V. This type of level signal is mainly for the conventional industrial control card, 5V CPU interface.
  

  The peak-to-peak value is 12 to 24V, and the jumper cap is inserted at 24V. This type of level signal is mainly for the conventional PLC interface.

• Conversion range: 0%-100% PWM conversion to 0-10V voltage
• Allowable error: 5%

Wiring instructions:

• VCC: Working power supply 12V-30V
• GND: Working power ground
• PWM: Output the positive end of the PWM signal
• GND: Output signal negative terminal
• VOUT: Input voltage 0-10V
• GND: Input voltage ground

Operating Instructions:
After power-on, when there is no input signal, the output is 0V.

For the first power-on, it is best to do a calibration debug: find a 50% duty cycle signal to the PWM, GND, Jumper caps set the corresponding voltage range.. The frequency is 1KHZ-3KHZ. Use a multimeter to measure the two ports VOUT and GND. At this time, the meter is displayed at about 5V. Adjust the potentiometer on the board so that the multimeter is displayed at 5.00v. This will calibrate your pulse signal and this module. the corresponding parameters. When the frequency changes, the corresponding parameters may be offset and need to be recalibrated. The output voltage can be adjusted by adjusting the duty cycle. Accuracy can be controlled by adjusting the potentiometer.
