Product introduction: This module is a module capable of converting voltage and PWM. The PWM digital signal is converted into 0 to 1OV analog signal. The output voltage is adjusted by the duty cycle of the entire PWM. V-PWM can convert 0-5V-10V voltage to 0%-100% PWM output, and adjust the PWM duty cycle by adjusting the voltage. Product parameter: PWM to voltage: Module working voltage: DC 12V-30V: (power power requirement: greater than 100MA) PWM signal receiving frequency range: 1KHZ-3KHZ: PWM signal input level range: Peak 4.5V to 10V level, jumper pin is inserted at 5V. This type of level signal is mainly aimed at the conventional industrial control card (such as MACH3 board) and the interface of 5V CPU; Peak 12 to 24V level, jumper pin inserted at 24V. This type of level signal is mainly aimed at the conventional PLC interface. Conversion range: 0%-1 00%PWM conversion to 0-10V voltage Tolerance: 5%. Voltage to PWM: Module working voltage: DC 5V-12V Output PWM frequency: about 50KHZ PWM amplitude: 5V Conversion range: 0-5V/0-10V Voltage conversion: 0%-100%6PWM Tolerance: 1%-3% Pin description: PWM to voltage: VCC: Working power supply 12V-30V. GND: working power ground. PWM: Input the positive terminal of the PWM signal. GND: Input signal negative terminal. VOUT: output voltage 0-10V GND: output voltage ground. Voltage to PWM: VCC: Working power supply 5V-12V. GND: working power ground VIN: input voltage 0-10V GND: Input signal negative terminal. GND: Output PWM ground. PWM: output PWMInstructions for use: PWM to voltage: After power on, when there is no input signal, the output is 0v, and there is output only when there is input. When powering on for the first time, it is best to do a calibration and debugging: find a 50% duty cycle signal connected to PWM, GND, the amplitude corresponds to the relative jumper. The frequency is between 1KHZ-3KHZ. 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 Correspondence with this module. When the frequency changes, the corresponding relationship may be shifted and need to be recalibrated. The output voltage can be adjusted by adjusting the duty cycle. The accuracy can be controlled by adjusting the potentiometer. Voltage to PWM: Connect the working voltage to VCC and GND. Do not connect them in reverse to avoid damage to the board and devices. Connect a controllable voltage at the VIN terminal. The voltage range is divided into two types: 0-5V and 0-1 0V according to the selected mode. The PWM output is PWM. The duty cycle can be adjusted by adjusting the voltage. The accuracy can be controlled by adjusting the potentiometer
