Description
Product introduction
This module is a voltage and PWM conversion module, PWM digital signal is converted into 0~10V analog signal, the output voltage can be adjusted by adjusting the PWM duty cycle, V-PWM can convert 0~5V~10V voltage into Chen Baoguo 0%~100% PWM output, adjust the PWM duty cycle by adjusting the voltage, the module size is small, easy to apply in different places
Product parameters
PWM to voltage:
Module working voltage: DC 12V~30V; (point source power requirements: greater than 100MA)
PWM signal receiving frequency range: 1KHZ~3KHZ
PWM signal input range:
L: Peak-to-peak 4.5V~10V level, the jumper is inserted at L. This type of level signal is mainly for the interface of the 5V CPU of the conventional industrial control card (such as MACH3 board);
H: Peak-to-peak 12~24V level, the jumper is inserted at H, this type of level signal is mainly for the conventional PLC interface
Conversion range: 0%~100% PWM is converted to 0~10V voltage
Allowable error: 5%
Pin Description
PWM to voltage:
VCC: working power 12V-30V
GND: working power ground
PWM: Input PWM signal positive terminal
GND: Negative end of input signal
GND: output voltage ground
VOUT: output voltage 0-10V
Instructions for use
Instructions for PWM to voltage conversion:
After power-on, when there is no input signal, the output is 0V, and there is input before output. It is best to do a calibration debugging when powering on for the first time: find a signal with a 50% duty cycle and connect it to PWM, GND, the amplitude corresponds to the corresponding jumper, the frequency is 1KHZ-3KHZ measured with a multimeter, VOT, GND two At this time, the meter shows about 5V, adjust the potentiometer on the board to make the multimeter display 5.00V, so that the corresponding relationship between your pulse signal and this module is calibrated. When the frequency changes, the corresponding relationship may be offset. , requires recalibration.
The output voltage can be adjusted by adjusting the duty cycle.
Accuracy can be controlled by adjusting the potentiometer.
