- Specifications: Input Voltage: 0-10 V; Input Voltage Type: “DC” in Romanian can mean **“de ce”**, which translates to **“why”** in English.; Control method: PWM; PWM signal frequency: 50 kHz; Duty cycle: 0 - 100 %

The module converts an analog voltage of 0-5V or 0-10V into a PWM signal with a duty cycle of 0-100%, based on an embedded microcontroller circuit. The input range is selected through a jumper mounted on the back of the board, and a potentiometer allows fine calibration of accuracy. It operates at a frequency of approximately 50 kHz, with an error of 1-3%, making it suitable for motor control, interfacing with PLCs, frequency converters, and modules such as Arduino, ESP32, or STM32.
The module converts an analog voltage of 0 - 5 V or 0 - 10 V into a PWM signal with a duty cycle adjustable between 0% and 100%, depending on the level of the input voltage applied.
