WOWOONE 1PC PWM to Voltage Module 0%-100% PWM Converted to 0-10V Voltage Suitable for Signal Interface Switching for PLC or Other Industrial Control Boards(PWM-to-Voltage 0-10V)

Parameters

Module working voltage: DC 12V-30V; (current greater than 100mA)

PWM signal receiving frequency range: 1KHZ-3KHZ

PWM signal input level range:

The peak-to-peak value is 4.5V to 10V, and the jumper cap is inserted at 5V. This type of level signal is mainly for the conventional industrial control card, 5V CPU interface;

The peak-to-peak value is 12 to 24V, and the jumper cap is inserted at 24V. This type of level signal is mainly for the conventional PLC interface.

Conversion range: 0%-100% PWM conversion to 0-10V voltage

Allowable error: 5%

Wiring instructions

VCC: Working power supply 12V-30V.

GND: Working power ground.

PWM: Input the positive end of the PWM signal.

GND: Input signal negative terminal.

VOUT: Output voltage 0-10V.

GND: Output voltage ground.

Instructions

1, After power-on, when there is no input signal, the output is 0V.

2, For the first power-on, it is best to do a calibration debug: find a 50% duty cycle signal to the PWM, GND, the amplitude corresponds to the corresponding

 jumper. The frequency is 1KHZ-3KHZ. 

3, Use a multimeter to measure the two ports VOUT and GND. At this time, the meter is displayed at about 5V. Adjust the potentiometer on the board so that the

 multimeter is displayed at 5.00v. This calibrates your pulse signal with this module. 

4, When the frequency changes, the correspondence may be offset and needs to be recalibrated. The output voltage can be adjusted by adjusting the duty cycle.

 Accuracy can be controlled by adjusting the potentiometer.
