PC Interface Controller

  • 【One-year after-sale warranty】The PWM to voltage module converts PWM digital signals to 0 to 10V analog signals. It can be used to switch the signal interface of PLC or other industrial control board. Adjust the output voltage by adjusting the PWM duty cycle. The module is small in size and easy to apply in different places.003cbr003e.
  • Using MCU embedded technology. Easy to operate, can be fine-tuned by potentiometer.003cbr003e.
  • Select the PWM signal input level range by short circuit. The module is small, easy to carry and easy to use.003cbr003e.
  • (current greater than 100mA)，PWM signal receiving frequency range: 1KHZ-3KHZ.
  • When power on for the first time, it is best to do a calibration and debugging: find a signal with a 50% duty cycle and connect it to PWM and GND. Jumper caps set the corresponding voltage range. When the frequency is 1KHZ-3KHZ, use a multimeter to measure the two ports of VOUT and GND. At this time, the meter displays about 5V. Adjust the potentiometer on the board so that the multimeter displays 5.00v.003cbr003e.
