PWM to Voltage Converter Module 0%-100% to 0-10V Digital to Analog Signal PWM Adjustable Power Module

Description

Product Overview

The PWM to Voltage Converter Module is an essential signal interface device designed to bridge the gap between digital microcontrollers and analog industrial equipment. This module converts a Pulse Width Modulation (PWM) signal into a proportional, linear 0-10V DC analog voltage, allowing you to control a vast array of industrial devices using simple digital outputs .

Many modern controllers like Arduino, Raspberry Pi, and various MCUs excel at generating PWM signals but cannot directly output a true 0-10V analog signal. This module solves that problem. By accepting a PWM input (0-100% duty cycle) from your controller, it outputs a clean, adjustable 0-10V voltage that can be used to interface with equipment expecting an analog control signal .

This converter is the perfect tool for integrating low-cost microcontrollers into industrial environments. Its primary applications include:

• Controlling the speed of industrial motors and pumps via Variable Frequency Drives (VFDs) .

• Precise dimming of 0-10V dimmable LED drivers and lighting systems .

• Interfacing with PLC (Programmable Logic Controller) analog input modules .

• Controlling valve actuators, dampers, and other industrial automation equipment.

• Providing a stable, adjustable voltage source for testing and laboratory applications.

With its wide input voltage range, selectable logic levels, and onboard calibration, this module provides a professional and reliable solution for translating digital control signals into the analog language of industry .

Key Features

• Digital to Analog Conversion: Converts a 0%-100% duty cycle PWM digital signal into a linear 0-10V DC analog voltage, with a typical allowable error of less than 5% .

• Wide Power Supply Range: Operates on a DC supply voltage of 12V to 30V, making it easy to power from existing industrial power rails or a separate 24V supply .

• Dual Input Logic Level Selection: Features a selectable jumper to match the voltage level of your input PWM signal :

  • 5V Position: For PWM signals from 5V microcontrollers (Arduino) and industrial control cards.

  • 24V Position: For PWM signals from 12V-24V industrial PLCs and controllers.

• Onboard Calibration Potentiometer: Includes a precision trimmer potentiometer that allows you to calibrate the module. By inputting a 50% duty cycle signal, you can adjust the pot to achieve a precise 5.00V output, ensuring accuracy in your specific setup .

• High-Quality Signal Conditioning: Employs embedded MCU technology and an operational amplifier (such as the LM358) for stable and reliable conversion, smoothing the PWM signal into a clean DC voltage .

• Opto-Isolation (Model Dependent): Many versions of this module include an optocoupler (like the PC817) to provide electrical isolation between the input signal and the output circuit, protecting your sensitive controller from electrical noise .

• Compact and Easy-to-Mount Design: Its small PCB footprint (approx. 33mm x 33mm) is ideal for mounting in control panels or enclosures without taking up valuable space .

• Clear Screw Terminal Connections: Features labeled screw terminals for secure and reliable connections to power, input signal, and output voltage.
