Functions: 1. Convert 0-100% PWM digital signal into analog signal. 2. The input digital signal can be a 0-100% PWM signal of 5V or 24V level,3. The output analog signal can be 0-10V voltage. 4. P-10V: Input 0-100% PWM signal of 5V or 24V level, and output 0-10V voltage5. Widely used in signal interface switching of PLC, microcontroller or other industrial control boards.parameter: 1. PWM signal receiving frequency range: 100HZ-3KHZ. 1KHZ-3KHZ is recommended. 2. PWM signal input level range: When the -to- value is 4.5V to 10V, the jumper pin is inserted at 5V. This type of level signal is mainly aimed at the interface of conventional industrial control cards (such as MACH3 boards) and 5V CPUs.When the -to- voltage is 12 to 24V, the jumper pin is inserted at 24V. This type of level signal is mainly aimed at conventional PLC interfaces3. Analog voltage output parameters, the following is explained by outputting 0-10V voltageAfter power on, when there is no input signal, the output is 0V, and there is output only when there is input.If it is required to power on for the first time, it is best to do a calibration and debugging: find a signal with a 50% duty cycle and connect it to DIN- and DIN+, and the amplitude corresponds to the corresponding jumper pin. The frequency is recommended to be 1KHZ-3KHZ. Use a multimeter to measure the AO and GND ports. At this time, the meter displays around 5.4V. Adjust the potentiometer on the board so that the multimeter displays 5.4v. This will calibrate your pulse signal and Correspondence of this module. The resolution of this module is 0.1V. Output current capability 10MA. If the relationship between the percentage of duty cycle and the voltage is opposite, you can check (or -check) the checkbox of the corresponding pin of STEP LOW and ACTIVE in the MACH3 softwareto set the PWM output pin.Color: greenMaterial: PCB+plastic+metalPackage Contents:1 x PWM Signal to Voltage ConverterOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
