(PWM to Voltage Converter Module 0%-100% to 0-10V for PLC MCU Digital to Analog Signal PWM Adjustabl Converter Power Module)

The PWM transfer voltage module LC-LM358-PWM2V converts the PWM digital signals into 0 to 10V analog signals.
It can be used as signal interface switching for PLC or other industrial control boards. The output voltage is regulated by adjusting the duty ratio of the PWM. The modules are small in size and easy to use in different places.

2. Features:

1>. MCU embedded technology

2>. Easy to operate, fine tuned by potentiometer

3>. Select the PWM signal input level range through short-circuit

4>. The module is smaller, easy to carry and use

3. Parameter:

1>. Work Voltage:DC 12V-30V; (> 100MA)

2>. PWM Receiver Frequency:1KHZ-3KHZ

3>. PWM signal input level range:

The peak of 4.5V to 10V level. The short cap install in ‘5V’. This level is used for normal controller or 5V MCU

The peak of 12V to 24V level, so inserted in 24V. The short cap install in ‘24V’. This level is used for normal PLC controller 

4>. Conversion range:0%-100% PWM to 0-10V

5>. Allowable error:5%

4. Hardware Interface:

5. Operation instructions:

After power on, without input signal, the output is 0V, so only input can output.
The first time when the power is on, it is best to do a calibration debugging:Input a 50% duty ratio signal to PWM/GND and adjust the relative amplitude short cap. The frequency is 1KHZ-3KHZ, Measured VOUT and GND with a multimeter and it will display 5V. Adjust potentiometer to make sure display 5.00V on multimeter. This will calibrate your pulse signal to this module.
When the frequency changes, the correspondences may be offset and need to be re calibrated.
The output voltage can be adjusted by adjusting the duty ratio.
The accuracy can be controlled by adjusting the potentiometer.

Voltage to Frequency Module

(Frequency Voltage Converter 0-1KHz To 0-10V Digital To Analog Voltage Signal Conversion Module Frequency Conversion To Voltage)

Overview:
The voltage to frequency module LM331_V2F is a module that can generate different frequencies depending on the input voltage. It is capable of converting 0-10V voltage into a frequency pulse signal of 0-10KHz.

Features:
1. Input voltage, output frequency signal.
2. The output signal can be fine-tuned, and the potentiometer can be adjusted to calibrate the correspondence between voltage and frequency.
3. The output of this module can be supplied to the driver for pulse signal. It must be connected to the driver for common anode connection. The relevant wiring is OC-OUT: PUL- or PUL12-30V connected to the driver: PUL+ or common terminal +5V connected to the driver, ( When powering 12V, it is necessary to string a 330R resistor. When powering 13-24V, it is necessary to string a 2.7K resistor to limit the current)

Technical Parameters:
Working voltage: 13.5V-30V.
Input controllable voltage range: 0-10V.
Output frequency range: 0-10KHz.

Wiring instructions:
VCC: Working power supply.
GND: Power ground.
IN+: Input voltage.
IN-: Input ground.
OCOUT: Signal collector output port (use this output port when equipped with a driver).
FOUT: Frequency output port (common frequency output port).
Two independent outputs, OC-OUT is NPN and FREQ-OUT is IC output. The common cathode end is matched with the negative GND of the power supply. When the common anode wiring is used with the power supply, when the common anode wiring is 13-24V, it is necessary to string a 2.7KR resistor, and the common anode wiring is 12V power supply. To string a 330R resistor.

Instructions:
The frequency pulse signal is connected to F, and there is a corresponding voltage output at the VOUT terminal.
Input and output correspondence:
1V = 1KHz
10V = 10KHz
If there is a deviation in the correspondence when using, you can adjust the potentiometer on the board to calibrate.
