Voltage to PWM Converter Module (0-5V/0-10V to 0-100%)

Description

Product Overview

The Voltage to PWM Converter Module is an essential signal conditioning tool designed to bridge the gap between industrial analog control systems and digital microcontrollers. This module performs the reverse function of its counterpart—it takes a standard analog voltage signal (0-5V or 0-10V) and converts it into a proportional 0% to 100% duty cycle PWM (Pulse Width Modulation) signal that can be read by digital devices .

Many industrial sensors, PLCs, and process control systems output analog voltage signals, while modern microcontrollers like Arduino, ESP32, and Raspberry Pi excel at reading digital PWM signals. This module solves that interface problem. By accepting a 0-5V or 0-10V analog input from your industrial equipment, it outputs a clean, linear PWM signal that your microcontroller can easily interpret using simple digital read techniques or input capture interrupts .

This converter is the perfect tool for integrating industrial sensors and controllers into DIY and embedded projects. Its primary applications include:

• Interfacing industrial 0-10V sensors with 5V microcontrollers .

• Reading analog signals from PLCs using Arduino or ESP32 digital inputs .

• Converting legacy analog control voltages for modern digital controllers .

• Creating adjustable PWM signals for motor drivers, LED dimmers, and power supplies using a simple potentiometer .

• Long-distance signal transmission (PWM signals are more noise-immune than analog voltage over long wires) .

With its selectable input range, adjustable output frequency, and compact design, this module provides a professional and reliable solution for translating the analog language of industry into the digital language of modern microcontrollers.

Key Features

• Analog to PWM Conversion: Converts a 0-5V or 0-10V DC analog voltage signal into a proportional 0% to 100% duty cycle PWM digital signal, with excellent linearity and accuracy .

• Selectable Input Range: Features onboard jumper pads or switches to select between 0-5V and 0-10V input ranges, allowing compatibility with a wide variety of industrial sensors and controllers .

• Adjustable Output Frequency: The PWM output frequency can be configured via jumper pads or potentiometer adjustment, typically ranging from 1kHz to 20kHz or even higher on some models, allowing you to match the requirements of your receiving device .

• Wide Power Supply Compatibility: Operates on a DC supply voltage of 5V to 30V (depending on model variant), making it easy to power from existing system rails or from your microcontroller’s power output .

• Dual Output Drive Modes: Many versions provide both PNP (positive) and NPN (open-collector) PWM output options, allowing interface with both sinking and sourcing input circuits .

• Onboard Calibration Potentiometer: Includes a precision trimmer potentiometer that allows you to calibrate the zero and span of the conversion, ensuring accurate mapping between input voltage and output duty cycle .

• Phase Selection (Inverting/Non-Inverting): Some models allow you to select whether the output PWM duty cycle increases with input voltage (positive phase) or decreases (negative phase), providing flexibility for different control system requirements .

• High PWM Resolution: Delivers linear 0% to 100% duty cycle mapping with accuracy typically within 1-5% , suitable for most industrial and hobby applications .

• Compact and Mountable Design: Small PCB footprint with mounting holes for easy integration into control panels, enclosures, or DIN rail systems.

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