PWM To 0-10V Converter PLC Digital To Analog PWM To Voltage Conversion

1. Function and function:

1. Convert 0-100% PWM digital signal into analog signal.

2. Input digital signal can be 0-100% PWM signal of 3.3V or 5V or 24V level

3. The output analog signal can be 0-10V voltage or 0-5V voltage.

4. Widely used in PLC; signal interface switching of single chip microcomputer or other industrial control boards.

5. The power supply has the function of preventing reverse connection

2. Parameters:

1. PWM signal receiving frequency range: 100HZ-3KHZ, 1KHZ-3KHZ is recommended.

PWM signals of other frequencies can also be customized.

2. PWM signal input level range:

When the peak value is 4.5V to 10V level, select the product whose input signal is 5V level. This type of level signal is mainly aimed at the interface of the 5V CPU of the conventional industrial control card.

When the peak value is 12 to 24V level, select the product whose input signal is 24V level. This type of level signal is mainly aimed at the conventional PLC interface.

When the peak value is 3.3V level, select the product whose input signal is 24V level. This type of level signal is mainly aimed at the 3.3V level microcontroller interface. 3.3V level is to order.

3. Analog voltage output parameters, the following is to explain the output 0-10V voltage:

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

The conversion correspondence is generally set at the factory.

When powering on for the first time, a calibration debugging can be done:

Find a signal with a 50% duty cycle and connect it to PWM-, PWM+, and the amplitude corresponds to the selected model, 3.3V or 5V or 24V. When the frequency is 1KHZ-3KHZ, use a multimeter to measure the two ports of AO and GND. At this time, the meter displays about 5.4V. Adjust the potentiometer on the board to make the multimeter display 5.40v. In this way, your pulse signal is calibrated with this module correspondence. The resolution of this module is 0.1V. The output current capability is 10MA. If the relationship between the percentage of the duty cycle and the voltage is opposite, you can check (or cross-check) the pin for setting the PWM output in the MACH3 software and click the check box of the corresponding pin of STEP LOW and ACTIVE.

4. The voltage range of the input power supply is 12-30VDC (power requirements: greater than 100MA), and the recommended power supply voltage is 15-24VDC.

At 12V level, the power supply cannot be powered by 12VDC, at least a power supply above 15VDC is required. If you must use a 12V power supply, you can also customize a 12VDC power supply converter.

3. The meaning of the port is as follows:

1. PWM+: PWM signal input is positive.

2. PWM-: PWM signal input is negative.

3. VCC: Positive terminal of power input.

4. GND: power ground wire.

5. GND: Signal ground wire. It is connected with the GND port of the power ground wire

6. OUT: Analog voltage (0-10V or 0-5V) output port.
