PWM to Analog Converter Module

Features:

• PWM to Analog Converter Module
• Adjust the duty cycle of the PWM signal to change the analog voltage output.
• Input pulse level can be 5V, 12V, 24V
• Analog Voltage Output Range: 0 to 10V DC
• Useful for using a digital pin to control analog devices.
• Screw Terminal Pinout:
  • VCC & GND: Power and ground for the converter module itself (12V to 30V on VCC)
  • VOUT & GND: Output analog voltage and ground (0 to 10V on VOUT)
  • PWM & GND: Input digital PWM signal and ground (connect to your microcontroller such as Arduino, Raspberry Pi, etc)
• Adjustable frequency to voltage ratio via onboard potentiometer
• Input level range of the PWM signal is selected by the onboard jumper
• PWM signal input level ranges:
  • 4.5V-10V (suitable for 5V boards such as Arduino) this is the default jumper position as shown in the images above
  • 12V-24V (suitable for PLC interfaces)
• Conversion range: 0% - 100% PWM duty cycle converted to 0 - 10V voltage
• Allowable error: 5%
• PWM signal receiving frequency range: 1kHz-3kHz
• Input to output ratio: 100Hz to 1V; 1KHz to 10V
• Can be calibrated using a meter to measure the output. The output voltage can be adjusted by adjusting the duty cycle and control accuracy can be controlled by adjusting the potentiometer.
